J.R. Alcorn Scapanus latimanus 1/2 mi. E Zephyr Cave, Lake Tahoe, Douglas Co., Nevada. Aug. 27, 1936. Many mole runs "bulges" were seen out through the conifer trees and along the small stream. All those that were out away from the stream were rather old & apparently the moles had been working this, now dry, ground in early spring when it was moist. I set a trap but none were caught. 3 mi. S Mt Rose, 8500 ft., Washoe Co., Nevada. Aug. 27, 1938 No. JRA 185a, 1929 and 188a. These three moles were caught along a small stream. Many other mole runs were seen. Most of the runs noted were very old & were out in the conifer forests where the ground was dry. All fresh runs were in moist ground. 1 mi. S Pyramid Lake, 3950 ft., Washoe Co., Nevada. April 21 1939, Near a small meadow I saw numerous mole runs today. These runs were out among the sagebrush. I did not have a trap or the time to catch any,

I caught this male among the Cottonwood trees near the river. The male runs are numerous along the river at this point. Some runs are in sand, gravel & then into rose bush thickets. ½ mi. S Pyramid lake, 3950 ft., Washoe Co., Nevada. Aug 30 Today I looked for mole runs 31, 1939 where I had been thme in April of this year. No runs were found in the sagebrush or dry part of the meadow but in the very moist part of the meadow mole mounds were seen. I dug into these mounds & found the runways were constructed by the moles were about 2 inches or 3 inches under the surface of the soil. By taking the soil into the hand & squeezing hard, water would drip out. The soil is very clayish in texture & the earth worms are sprehemly abundant in it.

J.R. Alcorn Sorex parustris 3-mi. S Mt. Rose, 8500 ft., Washoe Co., Nevada. Aug. 27, 1938 No. J.R. 186a. One ♀ shrew was caught in a mouse trap baited with a raisen. The trap was set along a small stream and although other traps were set in the vicinity this was the only shrew of this kind caught here. Kingston Creek, 7000 ft., Lander Co., Nevada. May 12, 1939. No. J.R. 283 ♀. As my wife was fishing in the stream, in a pool of clear, motionless water a fish appeared to be swimming along the banks. Back and forth it went in 2 foot circles as though feeding on something. Examining closer she thought it was a shrew so she came to tell me. I picked up the gun (with shot) and going within 10 feet of the water I was unable to determin what or why the shrew was so active. It was swimming rapidly back & forth along the bank and stirring up the water considerably. I took a shot at it and examination revealed that it was a ♀ with mammal developed. She must have had some very young ones somewhere.

These two shrews were caught in traps set along the waters edge + under an over-hanging bank. The traps were baited with "chewed" rolled oats. I believe a number of these shrews could be caught along this stream.

This shrew was caught about 10 or 15 feet from the water under a large tree. A bridge crosses the small stream at this point and the trees with pine needles come clear up to the water as the current is swift & the course of the stream too well defined to permit any grass to grow along it.

Alcorn 1939 Sorex vagrans small brown shrew Aug.10. Kingston Canyon, 7000 ft., Lander Co., Nevada. One & shrew was caught by tail in a trap set among the grass within a foot of the water. Several other traps in the vicinity were sprung and on them droppings that appeared to be shrew feces were found. Another trap set on wet soil under an over hanging bank contained one of these small shrews. As I reached for the trap the shrew freed itself and disappeared among the grass. Apparently it was caught by the end of the tail. The specimen mentioned above is no. 334 b. J.R.A. Baker Creek, 11,100 ft., White Pine Co., Nevada. Aug.15 no J.R.A. 351 and no J.R.A. 352. Aug.16 These two small brown shrews were caught in traps (mouse) set within 1 foot of the waters edge baited with rolled oats that I had chewed so they would stick to the treadle of the trap. Many traps were sprung apparently by these small shrews. Their droppings could be seen on sprung traps and I believe these small shrews are numerous along this stream.

R. Aleorn 1940. Sorex \frac{1}{2} mi. SW Mt. Shasta City, 3400 ft., Siskiyou Co., Calif. May 7, 1940. What appears to be Sorex vagrans were caught in a NE facing wet meadow. They are numerous and active both day and night. Setting 70 mouse traps, about 20 to 10 ft. apart, in runways, I caught 28 shrews in the last 24 hours. 7 shrews were taken today in the middle of the day. The animals are eating the bait and springing the traps on numerous occasions. W.C. Russell & F.H. Test also took about 20 shrews in the same general area. I have never before seen these shrews so numerous. Most of them were taken in moist or wet places where the grass is about 8 to 12 inches high.

This bat was first seen in the barn rafters as its squeaking directed my attention to it. The flies were numerous in the rafters & occassionally these flies would alight & otherwise annoy the bat at which time it would squeek and move slightly thus scaring the flies away.

Myotis 12 mi. E + 1 mi. S Fallon, 3950 ft., Churchill Co., Nevada. December 24, 1939 Today, Mr. Vernon Mills & Mr. W. H. Alcorn accompanied me on a trip along the foothills S + E of Fallon, Nevada. The object of the trip was to inspect all the caves that could be found & determine if possible whether any bats were in these caves. The first cave to be found as we traveled south along the hills directly east of Stillwater was the largest. This cave was over 150 ft in depth. With flashlights my father & I examined the cave for bats while Mr. Mills tracked a Lynx cat for several miles in the snow over the rough rocky hills. We found no bats in this large cave so we continued south for about a mile where we came to a cave with an

Once inside one can stand up with ease. A cross section of this cave is sketched as follows. Side view I entered first and thought I could hear bats squeeling so I summoned for Mr. Mills & my father to "crawl" in. We examined the larger portion of the cave but found nothing. At the place marked + I found a small bat (Myotis subulatus?) It was tucked into a small crevice at a point where the cave was about 4 feet high. Its eyes were open, its dark ears erect, and mouth shut,

I placed one finger on the back of the animal & it made a series of short squeals. It was 55° fahrenheit in the cave to " " outside the cave in the shade. No other bats were seen so Mr. Mills started to crawl out through the small opening when he saw a bat fly past him & out of the cave. When we all reached the outside, examination revealed the bat that flew out had alighted on an old bird's nest marked @ Mr. Mills captured this bat. Both of these bats were active but the first showed more fight than No 2. & I placed my finger on bat No 1 and its mouth was opened and it tried to cute me.

Dec. 24 A stick was put in its mouth + it took hold of the stick and "hung on" which enabled me to pull it from the crevice; at the same time I kept a finger on the animal to prevent it from flying away. The crevice was not over five inches deep nor more than three inches wide at the mouth of the opening. This short crevice was an a 45° angle + the bat was on the bottom of the crevice as illustrated Crevice Bat we continued on southward and examined about 4 or 5 more caves + found nothing. In one cave where in summer months I have often seen Corynorhinus no bats were seen. The temperature in this cave was 70° fahrenheit and between 40°+60° " outside of the cave.

Mills and Kay Beach I went to Yerington, Nev. from Fallon via Walker River Dam. Between Schurz + Yerington I noted several prospect tunnels in the mtn. so we stopped on the highway & walked to them. Near the main tunnel a tobacco can found in a rock monument read as follows: " Amado #2 J.W. Tobert 1/4 mi. S of Schurz road, 1/2 mi from Yerington."

This animal likewise was very inactive & when I dropped it on the floor it was not active enough to fly or move fast. In attempting to remove it from its crevice in the ceiling I noted that it clung to the rock so that some force was needed to pry it loose.

Alcorn Dec. 1939. Bats December 30, 1939. Washoe Co., Nevada. Today in company with Dr. Lundell Chapman & Vernon Mills I inspected two old mines about 3 to 6 mi. NE of Reno, Nev. in search of bats. None were found. The mines were both over 100 ft. in length. (3) Three mine tunnels over 100 ft. in length along the Truckee River Canyon about 4 to 8 miles E of Reno, Washoe Co., Nev. were also inspected for bats. None were found. Although the tunnels appeared to be suitable for bats, and it appeared that few people visited the mines, no bats or evidence of them was found.

Alcorn Oct. 24 (no 11a JRA) This hoary bat was noted just after sundown as it was flying amoung and around the large cotton- wood trees near my fathers house. I shot it and Mr. Stanley Jewett identified it for me. I had never seen any bats like this one before and have never seen any this large flying around here in the evenings.

J.R. Alcorn Corynorhinus rafinesquie 10 mi. SE Fallon, 3900 ft., Churchill Co., Nevada. Aug. 15 1938 In a cave in the foothills about 50 of these big eared bats were seen hanging from the ceiling. Three or four were captured for specimens. JRH Nos 178a, 179a. These bats have been found in this same cave for the past two years. It is interesting to note that they were always found in the far end of the cave where it is very dark as the cave makes a sharp right angle turn to the left which shuts out all light. 1 mi. S.W. Pyramid Lake, 3950 ft., Washoe Co., Nev. April 21 1939 As I was standing under a tree today mid P.M. a large bat (JRH 702 71) was seen flying just above the sagebrush. I shot it. Where it came from I do not know. Possibly it flew from a tree or from a pile of cliffs or rocks over by, " mile to the north. 10 mi. SE Fallon, 3900 ft., Churchill Co., Nevada.

Alcorn 1939. Corynorhinus rafenesque 2 mi. E 2 mi. N Yerington, 4700ft, Lyon Co., Nevada Dec. 27, 1939. In a 26 ft. tunnel made by miners a Corynorhinus was found hanging from the ceiling. The temperature was 50°, the bat was 18 ft. from mouth of tunnel; tragus straight out; ears coiled under wings, which covered the under surface of the bat. A gasoline lantern was placed near the bat and the heat from the lantern apparently caused the animal to move its wings & feet as though it was uncomfortable. All its movements were slow. No other bats were found in this short tunnel & this bat hanging into the air would have gotten cold enough to possibly freeze in colder weather, which is sometimes the below zero in this locality.

We did not find any more bats in this mine which was possibly due to the current of air which was coming through this niche. The bat was hanging downward & as it swung back & fourth slightly, it presented the appearance of a pear hanging on a tree swinging with the wind.

Vernon went into the cave and out flew one bat (adult) and hanging from her under surface were two young bats. I shot and killed the female (adult). I picked her up and struck both the young were hanging on to the Teats. Their teeth were stuck into her Teats so securely, it was with difficulty that I got them loose without pulling the teat off.

They all of these bats apparently were females and many flying out of the cave had from one to two young clinging to their teats of the adult ♀. Some with young would fly around outside of cave for about one to three minutes then return to the cave. Others flew out of cave with young & took a straight course out across the valley toward Carson Lake & to my knowledge did not return while we were at the cave. Several of these bats were shot with the following information: 3 ♀'s with no young clinging to teats as they flew out of cave. 2 ♀'s had 2 young each, as they flew out of cave 3 ♀'s had 1 young each, as they flew out of cave.

June 15 1939. young bats would always have their teeth sunk into the teat when the female was killed and they were not. These bats (Antrozous pallidus) are probably one of the most common bats seen around the edges of the valley along the foothills. I have never seen or collected one out in the floor of the valley but on scores of instances I have seen them in the following locations: Hills Edge of hills about 10 mi.

After spending some time in the vicinity my wife thought she heard a bat so by closer observations we found or rather we could see on favorable occasions a bat or two up in the crevice. I shot shot up into " & several bats fell from to the ground. This location, as I found in previous occasions, was in the foothills & at each time I have found & seen the bats in groups of up to fifty which indicates they are colonial

Two of these bats were found 120 + 138 ft. from the mouth of an old mine. Both were in short erevicies and one was pulled from the hole by a stick which was placed near the bat. As the animal bit the stick I gave a quick pull & before the animal was able to release its hold it was pulled out. Both bats ears were erect, eyes open and they were unable to fly and all movements made by them were slow. And a hissing sound was made as I placed them in a sack. The temperature in the mine was 60° F. I took them home & they became active & crawled about the cage as they became warm.

J.R. Alcorn 1938 Tadarida mexicana City Hall, Fallon, Churchill Co., Nevada. July 16 While waiting for my wife to come out of a beauty parlor I heard a sudden noise that sounded like many bats. I looked in the direction of the City Hall and there were dozens of bats coming out of the crevices in the newly constructed building. I observed these bats on 17 occasions from July 16 to August 18. Mostly about sundown to dark. During the day these bats were rather quiet. on many occasions appeared to be suffering from the heat as their mouths were open, showing their teeth, & they were panting. On each occasion just before dark & after sundown, before flying from the building a squeeking noise was (loudly) heard. After being rather quiet all day they apparently talked over the situations and then many bats took flight amid squeaks from the bats in crevices and those on wing. Within five minutes all bats (about 50 to 100) had left the building amid loud squeaks & then all was quiet until the following evening

No 177a J.H., was caught in this manner. Several dozen of these bats were in this cave. June 15 1939 On this day with Vernon Mills > went to this above location and within 100 yards of the cave where a colony of Antozous pellidus were rearing young a cave with Mexican Free tails was inspected. This cave is same as one "" on Aug 13, 1938 in company with E. Raymond Hall. As on previous occasion free tail American were found.

All embryos were well developed and after being pulled out full length and measured were 52 mm, 55 mm and 60 mm long. One embryo not measured. 2 dead. I noted that these bats occupied crevices just inside the cave instead of going back into the cave further away from the light. Fallon, 4000 ft., Churchill Co., Nevada. August 1939 walking down the street (Main) in Fallon I heard bats. I saw crevices just under the window sill so got a ladder & climbed 15 feet up where I could see into where about 10 or 20 Mexican free tail bats were found. Four window sill cracks contained from 10 to 15 bats. They were on the Southern exposure and looking into the crevice I could see the bats plainly. They could only get 8 to 10 inches into the away from the outer surface of the building.

J.R. Alcorn August 1939, Tadarida mexicana [4] Fallon, 4000 ft, Churchill Co, Nevada. It was the Sagebrush Cafet bar which is a two story structure. I watched the bats for 10 or 15 minutes and captured one with the aid of a stick. All the bats I looked at had their mouths open and were panting indicating the heat was warmer than to be comfortable for them. I observed these bats on several occasions in Aug. & on most all occasions they were panting with mouths open as though they were suffering from the heat yet they did not move to another location at least during my observation of them which lasted over a 27 day period.

Today as I walked up a stream to a high pass where I had set (yesterday) a coyote trap, I noted large bear tracks following up the trail along the stream. This bear apparently was traveling and not hunting. Going up hill N W up and beyond the head of the stream the bear tracks continued to go in the general direction of the trap which was baited with a Citellus lateralis. As I approached the pass, I also was tracking the bear, I noted that the bear tracks went directly over the pass within 15 feet of the trap & apparently the bear did not know the trap was there or the bait was not to his liking because judging from the tracks the Bear paid no attention to it.

I followed the tracks of the animal for about one half a mile but was never able to see the bear although fresh feces were noted and on one occasion I could hear something run through the brush and it was possibly the bear or some other large animal. This bear had been feeding in the vicinity because old & fresh tracks were plentiful & I noted several places where a bear had dug a few small holes & turned a log over.

Ursus Head Hunters Cr., 1/2 mi. S W Hunters Lake, 8000', Washoe Co., Nevada Today Vernon & Laura E Mills & I hunted bear in this region. We drove to Hunters Lake & from there walked two or three miles SW to a large meadow. We found bear tracks in many places and especially on this one location where they had been bedding down and both fresh & old signs (beds, feces, etc.) were seen in a dense thicket. We then walked north from the meadow for about a mile & there in the mud near a pool of water was very large bear tracks that were made within the past several days. We did not see any bear but so many tracks kept our courage up. We walked back to the car & returned to Fallon

Dec. 28. Yerington, Lyon Co., Nevada. Walker River Today I saw four Raccoon skins that were owned by Mr. Pearl Dun. Mr. Dun told me that he had caught & killed them on the East Fork of the Walker river at the Morgan ranch. He stated that one was killed in the day time this fall (nov.) as it was seen eating apples in an orchard near the house. 3 of the skins appeared to be of juvenile animals & one skin of an adult. He stated that the skeletons were thrown into the chickens. I went to the Morgan ranch (lower ranch) & the "hired help" said they had seen the skeletons about the buildings or orchard but a search by me & employees of the ranch failed to produce the skeletons.

Alearm 1939 Procyon lotor East Fork Walker River, Upper Morgan Ranch, Mineral Co., Nev. Dec. 28. Today I saw a large raccoon skin owned by Mr. W. E. Lewis. Mr. Lewis said he had caught three raccoon the past two months and had turned one loose & had sold the fur of another. He stated that the skeleton to the large skin was thrown into the brush along with a coyote carcass. The wolfed down to the river where the remains were thrown but the raccoon carcass was not found & the coyote remains were half eaten. Hogs were in this field & possibly they ate or carried the raccoon away. Mr. Lewis said he had caught a few raccoon in this vicinity every year.

J.R. Alcorn 1939 Spilogal gracilis March 5 West Walker River, Wilson Canyon, 4900 ft., Lyon Co., Nevada (no. 239 & JRL) within four feet of the water of the river among many rocks and willows a trap was set and baited with a small bird and this spotted sburb was caught. I approached it slowly, untied the trap from its object of a log and carried the spotted sburb to water where I put it into the water & held onto the chain to keep the trap & animal from going down with the current. The animal soon drowned and after I was sure it was dead it!! I took it out of the river. At no time did it emit any odor but as I approached, it would stamp its feet, and aim its back muzzle at me but after I was quiet a few minutes it would settle down so I could handle it. One must go very carey & slow to kill them in this way but it is worth it as they do not usually strike.

Going to the Wilson Ranch one of the hired men gave me a dead skunk & said another spotted " was in the cement & rock house which was used for food supplies etc. On entering the building I was told to be careful not to let the animal bite me or I would get "hydrophobia". The skunk was not in sight so I opened a cabinet & it was sitting on the 2nd shelf. It stayed watched me for a few seconds & then with the activity of a cat it jumped to the floor & ran under the cabinet. I took a sack & tried to place it over the animal but it was too active for me to catch. I then took a short piece of 4 inch pipe & ran the spotted skunk

Tajidea tatus On Pole Line Road, about 10 mi. N.E. of Hayen, Churchill Co., Nev. December 26, 1939. Today in company with Mr. Vernon Mills & Dr. Wendell Chapman I found where a badger had thrown fresh dirt out onto the three or four inches of snow which fell last night and yesterday. The hole about 8 or 10 inches in diameter was open & clean down for 2 1/2 feet at which point it was partially plugged. Only an inch or two clearance for was left from the roof of the tunnel to the top of the "plugging". This clearly showed that the badger was in this hole as all tracks lead into the hole & the plugged hole indicated that a badger inhabited it. Three traps were set at the mouth of the hole & a daily watch is to be undertaken to determine when the badger.

This desert fox was caught in a large trap(no.?) that broke its leg and the animal was dead when found. The trap was set in a small wash and baited with coyote scent. Prior to this date I have caught twenty or thirty of these animals in Churchill, Pershing- and Humboldt Counties[1]. Many times they die soon after being caught. On one occasion I caught one of these foxes in a trap and the Coyotes tore the animal to pieces,[according to tracks as evidence], and all I could find was the tail, some back fur and the coyote tracks covered every foot of ground 2 mi.

By burying the carcass and leaving only a little of the meat stick out of the ground the odor becomes very strong which attracts other Coyotes. If the carcass is left on top of the ground and not buried it dries out to fast, even so often coyotes will come and take the carcass away. On one occasion the coyotes had drug another coyote carcas away from the trap and I followed the trail left in the sand for about 1/4 mile but the coyotes were still going with the old dead carcass

This Sea Lion could swim very good. We could not get within 25 yards of the animal without it submerging so Dr. Jensen took several shots which injured the animals in the nasal region.

About 10 a.m.- in camp, my attention was attracted by a chatter of what I saw was a C. lateralis pursued by a long-tailed weasel, full grown, about 2 feet behind the Citellus. When Longhurst and I leaped for our guns the two animals were frightened; the weasel and squirrel ran in opposite directions and we saw neither again. The weasel had a white spot patch on its forehead. One Citellus lateralis was shot (not prepared) about 200 yds above camp.

J.R. Alcorn 1938 Citellus leucurus leucurus 5 mi. N+W Nixon, 4000 ft., Washoe Co., Nevada Mar.25 Today I was on a tufa point ½ mi. E of the Truckee River on the Pyramid Lake Indian reservation and while resting part way up the hill I noted 15 or 20 Antelope Squirrels running around in the tufa & rocks below me. They were close to one another and some were chasing each other. Two ran 20 ft from me and I killed both of them in one shot with the 41/0 gauge pistol. I shot 2 others from the same bunch and to my surprise all 4 were males as follows.

(1) March 20 I am writing to you in my new job, for the transfer from the previous place. The restaurant needs help. Let me tell you: you are very patient and learning quickly! On Mar. 21 we were able to get it all. In hours and days we got a good meal. Then we came close to each other. We tried hard, but I was so much of a stranger and I didn't know you at all. But then you took me in your arms. And I really felt like I belonged. I was singing for the first time. In my heart as well.

"Citellus townsendii" 3 mi. W and 1 mi. N Kennewick, 375 ft., Benton Co., Washington May 16, 1940. A colony of these Ground Squirrels are in a 10 acre field near the river. The ground is a level piece with a few scattered rose wild rose bushes growing on it, and some grass. The rancher nearby grazes his sheep on the area and keeps the grass rather short. When the colony was first seen about eight or nine squirrels were seen standing up near their burrows. after trapping, with rat traps, about 20 of these animals, none were seen standing in the field. The squirrels taken were very fat and I believe the adults were ready for aestivation. Some of the burrows appeared to be inactive and possibly some of the adults have already hibernated. Some of the area all squirrels seen on this side of the river are in this colony. We have covered a good deal of country setting Laphor traps but no squirrels take burrows were noted except in this one locality.

J.R. Alcorn 1940 Citellus townsendii mollis limi. SW Fallon, 4000 ft, Churchill Co., Nevada. June 20, 1940. Today in company with Laura E. Mills, we saw a Piute Ground Squirrel up in the tops of a buck brush tree. It was apparently feeding on the berries that it were ripening on this tree. Shot it and found that it was young and her stomach contained about ½ green vegetation and ½ Buck brush berries, by volume. It was 10 feet high when shot and was out on the amount the small branches of the tree. Its stomach was full and apparently all the berry was eaten because the seeds & skin of these berries were found in the stomach.

J. R. Alcorn 1936 Citellus townsendi mollis Feb. 13. 1936 4 to 8 mi. W of Fallon 4,000 ft., Churchill County, Nevada The Uinte Ground Squirrel appeared above ground today for the first time this year. May 19 1936 During the past two weeks I have ob- served a number of wet squirrels along the canal banks. I find these squirrels seem to want to move to different ground and a number of them deliberately swim across these canals which are running full of water. Some are 40 feet across which is quite a swim for a squirrel that likes dry land. Around the alfalfa fields these squirrels are getting very fat now and the young ones are growing very fast. These squirrels are very plentiful in the valley (Fallon, Nev.) and in the sagebrush and low hills. Like the Pocket Gophers here those around and in the alfalfa fields are larger than those in the sagebrush in the hills. Some of the ranchers while irrigating report killing 8 or 10 in one hole by drowning them out. Today I saw two blackbirds attack a Turkey Vulture that was flying about overhead. Vulture vomited twice losing. Copied from original notes by Mrs. J.R.A.

J.R. Alcorn 1936 1937 Citellus townsendi mollis May 19 1936 4 to 8 mi. W Fallon, 4000 ft., Churchill County, Nevada several ground squirrels that fell near me. A crow then came to the fight and took several feathers out of the Vulture. The Vulture did not attempt to fight back, but tried to get away. The Piute Squirrels are being killed by the ranchers in this district during irrigation. These squirrels are left flying out in the alfalfa fields. The Turkey Vultures are eating these squirrels and are having considerable trouble as they eat too many and the blackbirds and kingbirds attack the Vulture in the air and Mr. Buzzard vomits to enlighten his load and fly better. July 1936 The Piute Ground Squirrels have hibernated by the tousands. There are a few left where they were the thickest this spring. July 8 1936 There are very few Piute Ground Squirrels left that haven't hibernated at this date. Those left are very fat. Feb. 21 1937 The Piute Ground Squirrels appeared above ground today for the first time today this year. March 31 1937 4 mi.

April 8 1937 I dug into a squirrel hole today and the hole took a 45° angle until it was 3 1/2 feet deep then it leveled off for several feet and there in a side chamber 6 or 8 inches in diameter was a nest of dry grass. We were poisoning in this section several days ago. Close to the nest was one dead female. In the nest was 15 blind naked young squirrels. April 12 1937 I weighed several Pinte Ground Squirrels and weights as follows: 5 males; one 5 ounces, one 5 1/2 ounces. 4 females; one ovaries normal 4 ounces. one being suckled 7 ounces one being suckled 7 ounces one being suckled 5 ounces Feb. 14 1938 4 to 8 mi.

I was about to give up when five miles west of Fallon, Nevada I saw a drain ditch bank that had a squirrel or two on it. This ditch ran North and South. I stayed around this bank which was 1/2 mile long, for about three hours and managed to kill 8 squirrels. Information collected as follows: Squirrel No. Total Length Tail H.

Apparently this was a nice warm place for them, as they are not so thick yet any place else in the valley. All squirrels except Nos. 3 and 6 had very full stomachs. Nos. 3 and 6 were empty. Nos. 3 and 6 were very fat, having a complete layer of fat up toward the squirrel head as the lungs or stomach. All the squirrels had some fat. No. 1 had only a small amount back toward its rectum. Feb. 17 1938 The squirrels may be seen scattered all over the valley. All of them haven't come out of hibernation yet.

J.R. Alcorn Citellus townsendi mollis 20 Nevada: Churchill County. A number of these squirrels were collected in Churchill Co. and their numbers are as follows J.R.Alcorn no's. 1, 7, 35, 57, 62, 150, 164, 245, 246, 247, 248, 249, 250, 251, 252, 253, 254, 255, 259, 261, 262, 263, 273, 274, 275, 276, 277, 278, 279, 280, 281, 282, 290. For information on these see Catalog and original note books on Citellus t. mollis. A number of the above specimens are very light (almost pure white) in color. All light colored ones are in M.V.Z. A few of the natural colored ones were given to the U.S. Bureau of Biological Survey.

Alcorn 1939. Eutamias Aug. 13. Baker Creek, 11,100 ft., White Pine Co., Nevada. Lyson returning to a cabin (that is our camp location) after being gone all day a mouse trap set at the outside corner of the cabin contained one of Eutamias (no. 343). No others were seen during our entire stay at the cabin in the immediate vicinity. About 1/2 mi. above the cabin I saw several of these animals and above Treasury Lake at 12,200 ft., several were seen. One at this point became very curious and as I sat on a rock in the open the animal came to the edge of a low tree and there spent considerable time looking me over. I sat as motionless as possible and the animal approached within ten feet and carefully looked me over. I moved and it ran to a tree and disappeared.

J.R. Alcorn Sciurus douglasii Aug.30, 1/4 mi. E Zephyr Cove, 6300 ft., Douglas Co., Nevada. 1936 One (no 81a JRL) was shot today as it started to cross a small meadow. They are numerous in this section and are usually seen running up a tree. 1/2 mi. E Zephyr Cove, 6500 ft., Douglas Co., Nevada. July, 4, 1938 One (no 168a JRL) squirrel was caught in a trap that was baited with several raisins on the treadle of a rat trap. These squirrels are numerous in this section. I saw seven in a one mile walk up the mountain. 2 mi. E Incline, 7700 ft., Washoe Co., Nevada. Aug.28, 1938. (no 193a JRL) was shot as it ran up a tree. I set traps near several holes along Incline Creek and caught one of these squirrels. I also caught 7 squirrels out of 25 traps set for flying squirrels along this stream in the heavy timber so they must be fairly common.

J.R. Aleorn 1940 Thomomys ? Yellowstone River, 5 mi. W Forsyth, 2750 ft, Rosebud Co., Montana. June 8, 1940. In a grassy field near camp many Gopher mounds were seen. Traps were set and a few Gophers were taken. In setting the traps I noted that the lateral varied in length from about 1 1/2 to 2 feet and the both the lateral and main burrow were large for the size of the Gopher. I could stick my arm down many of the burrows. Most of the Pocket Gophers taken were F's and they apparently were lactating or had already weaned their young. The soil is heavy and without rocks. The mounds made by the Gophers are large, some 1 1/2 to 2 feet across.

Alcorn 1936. Thomomys batiae canus Feb. 20. 4 mi. W. Fallon, 4000 ft, Churchill Co., Nevada: The pocket gophers in this area are quite numerous and many mounds may be seen in the fields. The soil is moist and there is not any frost in the ground which possibly is the cause for much activity at this time. On one 20 acre field of alfalfa I walked completely across it by stepping only on the mounds of earth thrown out by pocket gophers. Several were caught and the lice were crawling all over the animals: I left the[illegible]gophers in the sun a few minutes and hundreds of these lice began to crawl about [illegible] on each animal. August 19. I caught one female Gopher in a trap today at entrance of burrow were 2 young gophers, apparently started out of the nest and went in search of their mother. Both small gophers were approximately the same size. Measurements of

Far Aug 5 One female weasel caught in gopher trap measured 13 3/8 4 7/8 1 1/2 1/2. Dec. 1 On Dec. 1, 1937 I made some experiments on poisoned bait for Pocket gophers. I took sweet potatoes and cut six baits 3 1/2 in. long and 1/2 in. square making an oblong piece of sweet potatoe. In making them so long and big I planned on having them too large for the gophers to carry and they would then have to eat them or cut them at the place the bait was put into the tunnel thus killing the gopher at that point. I placed three of these baits into a group of about Ten (10) mounds at four o'clock in the afternoon. The following afternoon, I examined all three baits and found no trace of two of them and one was untouched. I started digging and after following the tunnel for some distance across an alfalfa field at a depth of about six or eight inches came the way. It came to a high piece of sandy soil. Digging descended to a depth of some 3 1/2 feet. In the tunnel a male gopher was found dead. Following the tunnel three feet farther a newly constructed nest was found made of cut pieces of dry grass. In this nest several small pieces of alfalfa roots were found and one piece of the sweet potatoe. What happened to the other piece of potatoe I do not know. However, this gopher had 3 1/2 inch piece of bait (covered with strychnine)

I have ran other experiments with other smaller lengths of bait and have found that the gophers usually prefer to take the bait to the nest. and apparently eat them there. We are now using sweet potatoes cut 2 inches long and 1/2 inch square, put them in a dishpan and sprinkle 1/4 ounce of strychnine Alkaloid over one gallon of cut sweet potatoes and are getting very good results. Jan. 6 1938 4 mi. S Fallon, 4000 ft., Churchill County, Nevada I set gopher traps and found the following information. Measurements were taken and ovaries examined.

It is important to note the scarcity of males found in this field. The females had no embryos in them, which indicates the males must be present in considerable numbers to produce a maximum of young. In other words if the males are continually after the females the weaker sex gives in. Feb. 9 1938 On February 9, 1938, I placed two or three poisoned (Strychnine alkaloid) Carrot baits 2 in. long by ½ in. square into a gopher tunnel in different places. On Feb. 10, 1938, I dug this tunnel system out and found the following: At no place did this tunnel go more than one and one-half (1½) feet deep. The nest, made of dry cut pieces of grass, was found. About four or five pieces of alfalfa roots 1½ inches

The end of the carrot had been eaten away. The nest was 1 1/2 feet under ground and was in a cavity in the dirt 10 inches in diameter. Two feet from the nest was a cavity five inches in diameter filled with gopher "droppings" or stools, and seven pieces of alfalfa roots about 1/4 by 1 1/4 inch long with all the bark eaten off. This rubbish or waste had been tightly packed into this cavity. Four feet from the nest another cavity of the same size was found with 87 pieces of alfalfa roots the same as in the cavity two feet from the nest. Five feet from the nest was another cavity with 40 pieces of alfalfa roots with bark peeled off. All the three above cavities were apparently garbage rooms for the gopher and all were tightly packed with droppings plus what roots were mentioned. Thirty feet from the nest a food storage chamber was found which contained 876 pieces of alfalfa roots. 100 feet from the nest another food storage chamber was found containing 1561 pieces of alfalfa roots. 115 feet from the nest a third storage chamber was

J.R. ALCORN 1938 Thomomys battae canus Feb. 9 4 mi E Fallon, 4000 ft, Churchill County, Nevada was found which contained 336 pieces of dry hard cut pieces of alfalfa roots. Apparently this third chamber had been forgotten or else the gopher had cut more food than he could eat and it had died out on him. The third chamber was on a high knoll in dry soil which contributed to the shortness of time it took for these roots to dry out. I have noticed when I dug these roots out and get them into the dry air they dry out in a day or so and get as hard as wood. A gopher usually stores these roots far enough under ground so that they keep moist thus keeping them from drying out and getting hard. The roots mentioned, in the third storage cavity these roots were dry and hard while those in the cavities were in moist ground which kept them soft and edible for some time, as for as the gopher is concerned. There were one hundred fifteen (115) yards or 345 feet of tunneling system that was in this gopher's house. The male gopher, a good size one, was found dead about thirty (30) feet from the nest. This gopher and all the contents of the tunnel were photographed.

It is interesting to note the difference between these last two lists. 35% of the above females were pregnant while on the first list where the males were scarce 100% of the females were free from embryo. Yet the gophers were more con- centrated than on the first list. These two fields were about 1/2 miles apart.

J.P. Alcorn 1938 Thomomys bottae canus (17) Feb. 18 1938 2 mi N S R Alcorn Ranch Fallon, 400 off?, Churchill Co., Nevada. On Feb. 18, 1938 a gopher was dug out in the Soda Lake District 2 mi. North of the J.P. Alcorn ranch. Poison carres had been placed in the tunnel several places on Feb. 17, 1938. The distance, in feet measured between comparatively new looking mounds in feet, as follows, from end to end. 10, 20, 12, 12, 8, 17, 11, 11, 7, 10, 10, 18, 12, 4, 2, 8, 12, 2, 12, 9, 13, 4, 12, 4, 4, 3, 5, 10, 13, 17, 4, 5, 7, 7, 8, 6, 6, 12, 10, 9, 18, 9, 2 4, 11, 7, 11, 9, 8, 10, making a total distance of 477 feet. The male gopher was found dead from eating the poison in the tunnel. There was no nest or storage chambers of any kind found in this tunnel system. Either he didn't have one or else we missed them. Above was in an alfalfa field and 45 crowns were found that were cut off (and thereby killed) about five inches below the surface of the ground The depth of the tunnel varied twenty-four inches up to four inches in depth, however, eight inches is a fair average. The normal gopher tunnel system at this time is 200 feet of tunnel / 5 mounds, one nest 10 inches in diameter located to 1 1/2 or 2 feet underground, and on a more storage chamber.

Alcorn 1939. Perognathus parvus Aug. 10. Kingston Canyon, 7000 ft., Lander Co., Nevada. In a stream about three feet wide a small rock stuck out of the water about four inches. On this rock I set one mouse trap and looking for the trap in the early morning I found it had washed down stream 4 or 8 feet and in it (no.329) was the Perognathus. Apparently, in crossing the stream the rock was used to lessen the distance the animal would have to jump without getting wet. Dense vegetation lined both sides of the stream at this point. Mostly willows and birch trees.

I counted the kernels from the two outside pouches of one of these and found 29 kernels in the left pouch and 24 kernels in the right pouch total 53 kernels of strychnine coated rolled oats in the pouches of one Dipodomys merriami. This aroused my curiosity as to the effect of this much poison in the stomach of one coyote. The coyote tracks are numerous in favorable localities and in several places I followed these tracks across the sand and could plainly see where the coyotes were apparently picking up the dead kangaroo rats.

Alcoro 1938 Dipodomys merriami merriami and they must have eaten them for food. Will this this much poison kill a coyote? On several occasions I noted where the coyotes or rather one coyote had picked up three kangaroo rats for food. The rats when poisoned sometimes many times leave their tracks & tail marks very plainly on the sand and one is clearly able to see where they have died and where the coyotes have come along & taken them. I took a pointer dog and gave (by force) it 50 kernels of this same poison rolled oats and in 15 minutes the animal was apparently not affected. In 20 minutes the animal acted as though it was drunk. In 29 minutes the animal was dead. This dogs stomach was empty to begin with and therefore the poison should have been more effective than if it was full or part full. If 50 kernels

Alcorn 1938 Dipodomys merriami merriami will kill a pointer dog what effect will kangaroo rats, whose pouches hold fifty or more kernels, have on the coyotes in the vicinity? I am not sure it will kill the coyote because I was unable to locate a dead coyote but I did not trail any one coyote more than one fourth to one half mile. and I do believe where a coyote eats several rats with full pouches the effect is many times fatal. 5 mi.

Considerable Russian thistle was growing among the sagebrush in the area. Mostly all of the animals had their pouches filled with poisoned rolled oats that was distributed for ground squirrels. One male whose pouches were full of strychnine coated rolled oats was picked up and the kernels counted. A total of 31 kernels of rolled oats were counted from the two pouches of this male. On examination of the uterus horns the tubes were of some females were greatly enlarged and flabby also reddish in color. This indicated that the young female had recently given birth to young and the tubes or uterus had not had sufficient time to contract to their normal size.

J.R.Alcorn 1940 Castor canadensis Yellowstone River,5 mi.W Forsyth,2750 ft,Rosebud Co., Montana. June 4, 1940. I was standing on the bank of a small branch of the river when I looked downstream and saw a Beaver swimming toward me. I sat down and the animal approached to within 30 ft. of me then dove and re-appeared about 50 ft. upstream. It swam close to the bank and much of the time it was almost out of sight because of the overhanging willows. When about 150 ft. away I stood up and the animal gave a number of "splashes" which made a noise like someone throwing a 10 lb. rock into the water. This noise was apparently made by slapping the water with the tail. June 5, 1940. In this same general vicinity today I saw a number of Cottonwood trees that had apparently been "fallen" by beavers. Some of these trees were 14 inches in diameter. As I walked up the river (N bank) I could see many beaver tracks in the mud and one beaver house was built in the edge of the water. I noted that both

Many willows are growing along the bank of the river and many of these have been cut by beaver about 6 to 10 inches above ground and the willows in turn have sprouted out and kept growing.

The nest consists of sticks, cactus, leaves or any other loose material that is available close to the tree. The nest, being up in the tree, is dry and when the river comes up and floods the ground it does not get wet. At a distance the nests look like magpie nests. At first glance their rats look like squirrels as they run up into the tree when one disturbs their nest. They jump from limb to limb with ease and I believe much of their life is spent in the trees. The water had been up around some of the trees with nests for several weeks making it difficult for the rats to reach dry land. They would have to swim from 30 to 60 feet to get from the tree to land. Greese wood (Sarcobatus) sticks had been used to make part of the nest & I noted much of the barks had been eaten off these sticks

J.R. Alcorn 1938. Jan. 25 Neotoma cinerea 1 mi. E Weeks, Carson River, Lyon Co., Nevada a small nest 1 1/2 feet in diameter was noted 20 feet above the main nest. By probing into this nest (main nest) a rat ran up the tree into the small nest. Many droppings were noted as I ascended the tree. Droppings were in the main nest, the small nest and in the crevices of the tree. Apparently rats had occupied this tree for a long time from the amount of droppings. I ran the rat all over the tree and never caught it because it was too clever to get where I could shake it out of the tree and the tree was too large to corner it. In this same area a small clump of Buck (bull) Brush about 20 ft. wide x 40 ft. long was growing. In this clump I noted a rats nest on the ground and built up around a (Sarcilbatus) brush.

Jan 26. Dear Mr. Furlong, By sending into the car two men for a wood that was to be cut off of the land, but all I saw left to do is to let them know it should be split and piled up so they can get back with their trucks for lumber. This would have been quite possible if there had not been an attempt made by someone else to return before we could see him. I am sure that no one has any idea of what to do next, but I think we should try to get the job done as soon as possible. We have tried our best to make sure the work is completed on time and with quality. If anything goes wrong, please let us know so we can fix it up for you before the trees are cut. I will try to call you at 10:30 a.m. tomorrow if possible. Please feel free to call me back anytime after that hour. Sincerely yours, Mr. Furlong

Many runs were noted in the Lesino Clover but in Meadow Fescue (a grass) were few runs, yet both were growing side by side. The Strawberry Clover was growing in a plot next to the Lesino Clover and both clovers contained approximately an equal amount of runways. The Meadow Fescue, Lesino Clover, Strawberry Clover were all in long narrow strips (30 ft.) adjoining each other.

The traps were baited with chewed Rolled Oats & traps placed across way of the runways. As mice were caught accross the end of the trap instead of pointing into the trap I gather that these mice have no special taste for the oats. I also noted where these mice had partly covered several traps with dirt by their tunneling activities but did not touch the bait.

For several nights I was unable to trap any of these animals near this location. Yesterday I noted many runs of some small mammal among the dry, E. sloping, grassy land about 100 feet from the nearest water. Some large timbers (12x12) were loosely scattered about over a 50 foot square area. It was in near these timbers that most runs were seen. Droppings in the runs did not look fresh and I noted that grass was starting to grow in the runs in many places. These facts lead me to believe that the mice, for the most part, had abandoned the location or possibly some were killed by

This was in the bottom of a E running small canyon and the grass was shaded most of the day by the growth of conifer trees. It is rather a dry location and no water is within 150 yards of the runs. I am unable to explain why these mice apparently favor the dry grassey areas to the wet " " along the small stream. Traps which I set last night were baited with "chewed" rolled oats and set about 4 ft apart over an area of 40 feet square.

Ondatra J.R. Alcorn 1940 Canvasback Gun Club, 5 1/2 mi. N Stillwater, Churchill co., Nev. Aug. 25. Mr. L.R. Emerson of Stillwater, Nev., has lived on the Canvasback Gun Club hunting grounds about 10 yrs and relative to Muskrats Mr. Emerson says, If the rats are able to burrow into a bank and get above water level or high water, they do so, otherwise they build a house of dead tiles and there make a nest. This house has from 2 to 5 openings all under water. The house averages about 4 ft. above water line. House is about 5 feet in diameter at water line, depending of number of rats using the house. ?th winter, 15 to 30 rats use one house. The colder the weather the more rats to be found in one nest. The more rats to a house, the greater diameter at water line that house is stays about the same height.

Rats in this area live almost entirely on the roots of cattail and tule. The lower (in) [illegible] of the stalk is also eaten. The cat tail is preferred by them. Fresh water mussels are also eaten in winter. No evidence of mussel eating is noted about feeding stations in the summer. All feeding is done away from the nest. Occasionally a half eaten carp is seen at feeding station. Matted down tule [illegible] consist make up the feeding station. The rats often make these stations and these "platforms"

Big ones are in sheltered places and many rats use these large "platforms". In real cold winter the rats (about 75%) of them leave the sloughs and lakes and migrate up into the sloughs and drain ditches. Rats are most active just before and after sundown. Young found in nest average about 7 to nest. Has attempted to move nest from "blinds" into a safe place but rats always desert. Often dead rats are found in early summer. One ♀ found dead on ditch bank had 6 young in radius of 6 ft. of ♂, Young were about starved but were alive and had their eyes open. Young were size of field mouse. Live rats in traps are often attacked and partly eaten by marsh hawks.

Andatra z. mergans 6 mi N Stillwater, 3900 ft, Churchill Co., Nevada. August 25, 1940 Today, in company with [illegible] J. Mills, we were riding in a small motor boat and out in a lake we observed a muskrat. The nearest land was several hundred feet but tules were growing all around." I shot at the animal and wounded it but it "came to life" and escaped into the tules before one could get it. He observed the animal several times swimming from out in the lake into the tules before I shot. It was not a cloudy a clear day, with some wind. Observed animal at 3:30 PM.

J.R. Alcorn 1939. Ondatra zibethica S.W. Corner Walker Lake, 20 mi. S Schurz, Mineral Co., Nev. April 16. (No's JAL. & 257, & 258.) While going along the highway with Vernon Mills today we saw what appeared to be a grebe swimming low in the water. We were a considerable distance away but a shot from a 22 Rifle & the animal dove. We approached closer & could see the muskrat was not a bird so we shot it. Going farther to the south we stopped on some high cliffs & there below us was another muskrat swimming along in the water next to the cliffs. I crawled down near the water & as the muskrat started to swim by me I shot it with the 410 pistol. There is not any plants of any kind growing in or near the water so I don't see what these rats live on unless it is algae.

Alcorn 1939 Mus musculus 2 1/2 mi. W Hazen, Truckee Canal, Lyon Co., Nevada. Nov. 12. In the weeds along the Truckee canal many runs may be seen & in these runs the House mouse was caught. The grass is nice & green on southern exposure and it has grown up 4 to 6 inches because the exposure & the water help to keep the grass from freezing in these cold nights. On two occasions these mice were caught in traps that were set 6 to 10 inches from where Reithrodontomys were caught and apparently these 2 species of mice were living in the same habitat and both thriving nicely.

J.R.Alcorn 1940 Odocoileus hemionus yellowstone river,5 mi.W Forsyth,275ft, Rosebuds., Montana. June 2,1940. A small deer (mule tail ?) was seen this afternoon. We were all in camp when the animal was seen to come within 40 yards of camp. It was not wild and we watched it for several minutes before it disappeared into the timber up the river. Its tail+rump were white+ tail had a blue tip. It apparently was a mule tail deer. Several ranchers in this vicinity have told me that a few deer inhabited the river bottom in this section.

J.R. Alcorn 1940 Lepus californicus W slope Granite Range, 6000 ft, 13 mi. N and 6 mi. W. Deephole, Washoe Co., Nevada. Aug. 30, 1940 In this location, the edge of a valley, where a few antelope [illegible] and horses water at a small spring, I was leaning against the bank of the wash. Being in the shade of the bank, and making no movement I was apparently not noticed by a Jackrabbit that appeared on the opposite bank of the wash not more than 50 feet from me. This jackrabbit "zig zagged" down the 10 ft. slope of the wash by short gentle hops, and it appeared to be in no hurry. When it approached the edge of the water it stretched its neck out, apparently as far into the spring as possible, and drank for a minute or so, then it turned and with great speed ran up onto the bank where it stopped and looked about then leisurely hopped out into the sagebrush. I do not believe this Jackrabbit was aware of my presence. It was 7:05 A.M by my watch.

J.R.Alcorn 1940 Antilocapra W Slope Granite Range, 6000 ft., 13 mi. N and 6 mi. W Deephole, washoe Co., Nevada. August 30, 1940 This morning I got up early, circled the floor of the valley looking for Antelope and as I was returning to the small spring I saw what appeared to be Antelope coming down the gentle WNW sloping hill. I jumped into a deep wash and was making my way up hill when I met my father who had just been over on the ridge to the N. We looked about for the Antelope and saw them, to my surprise, below us. There was five in this one bunch and the sun was shining on them as they stood broad side. I slipped back into the wash and ran down hill to - within 350 yds. of the animals and they were still standing broad side in the same place. My automobile was near the spring and these antelope were apparently standing in this place looking at the car. They stood out conspicuously from where we were. To see us they had to look directly toward the sun.

J.R. Alcorn Antilocapra 13-mi.N and 6mi.W Deep Hole, Washoe Co., 6000ft., Nevada. Aug. 30. We were unable to approach closer so a quick examination showed One buck (O) Two large F and two half grown lambs. Shooting several times, a leg was broken on one F. They ran over the hill and my father trailed as I scouted around. On passing over the crest of a large hill we came upon the whole herd. The crippled animal from 150 to 200 yds. was plainly visible and a shot or two fell the animal as it ran through the brush. The udder of this animal contained milk. We easily milked out several squirts. She weighed 105 1/2 pounds. Most of the vegetation is Artemisia (sagebrush). There is a scattering of bitterbrush and judging from tracks these animals appear to be feeding on this plant. It was remarkable how this animal went up and over this mtn. with one hind leg broken. It could have easily gone down hill but chose to go up with the rest of the herd. We carried the animal to the car and left 10:00 AM, for home. Traveling across the small

One was a buck, one a large female and one, one half grown lamb. There was a spring within 200 yds. where we first saw these animals with Artemesia (black sage), and Bitterbrush to main vegetation growing in this immediate section. No trees are within several miles from here. Wild horses and many Cattle are in this section. Three mustangs, three gentle horses and over 50 "white face" cattle were seen by us around this small valley, in this mornings, walks and last night activities. Coyotes were heard howling much of last night and several "poor well" birds were heard calling.

J.R. Alcorn 1940 Antilocapra americana (1) Wslope, Granite Range, 4000 ft., 13 mi. N and 6 mi. W Deephole, Washoe Co., Nevada. Aug. 30, 1940 About 8:30 A.M. my father noted an antelope to the NW of a small hill where we were standing. A small short spring ran for about about 1 mi. 100 yards below the hill. The antelope was first noted walking toward the spring. As the animal approached from the floor of the sagebrush covered valley it was noted that it did not come in a straight course, instead it zig-zagged back and fourth, stopping every 100 to 200 yards to look about. The “kid” behind a large lava rock and I do not think the animal was aware of our presence. It walked up the lower end of the water where cow filled tracks afforded it drinking water. Before drinking it looked about for some time as it stood motionless, then it drank it- the for several seconds then raised his head and looked about then walked.

I took my white handkerchief and placing it on my gun barrel, waved it frantically attempting to "get the animals attention" as it started walking from the spring. It apparently did not see the handkerchief so I issued a very short whistle. The antelope immediately stopped, turned broad side and looked for several minutes at the white handkerchief that was "hoisted" from 1 1/2 to 2 feet above the rock. I then started moving the handkerchief from side to side (radius of inches) but after as looking at it for several seconds it started walking toward the valley again. Another short whistle and the antelope again stopped and looked at the handkerchief for several

After another attempt to attract the antelope closer by "the handkerchief method" I sat up high enough so that my head and shoulders protruded above the rock and issued a short whistle. The antelope stopped took a good look at me then walked several feet and broke into a trot then into a high rate of speed as I sat on the rock. After running for 1/4 mile it stopped to look about again and then disappeared into the valley. We were not over 100 yds. from the animal while it was drinking and we were located on a small hill (about 20 ft. high) that was to the east of the place where the antelope was drinking. His horns were visible but it was not a large ♂.

J.R. Alcorn 1939. Antilocapra americana Americana antelocarpa 5 mi. S. Nyala, 4600 ft., Nye Co., Nevada. Aug.22. Two antelope ran across the road at this point. The desert is very flat with low brush and one is able to see an animal of this size for many hundreds of yards. I shot one of these Antelope and Wm Longhurst prepared it as a specimen. We took the following information Weight 105 lbs. ♀ 1270-80-440-155; Stomach contents chewed beyond field recognition except four or five parts of Cottonwood tree leaves were distinguishable. Correction = leaves of some tree, probably Cottonwood, as these trees were growing along Big Creek and in other places where water is available and probably these green leaves were found and eaten when the animal went for water. Above animal is original number 480 w/m Longhurst. Museum of Vert. Zool. Number 88135 Skull + skin and skeleton. This ♀ apparently did not bear young this year.

J.R. Alcorn 1939. Ovis Aug. 13. Baxter Cr., 11,100 ft., White Pine Co., Nevada. Wm Longhurst and I arrived at this location (via horses) today and set up a camp in an old prospector's Cabin. Ralph Kauffman of Baker, Nev. and several of his associates say that Mt. Sheep are in this vicinity and Ralph K. says he shot at one near here this spring. He said it was too far to tell whether it had horns. These people give one the impression that a person should be able to kill a Mt. Sheep with little difficulty and thus know where the sheep range but were unable to go with us to hunt for them. I am inclined to dis believe they know much about it and doubt if Kauffman ever shot at a Mt. Sheep. I think they are sorta spreading it.

Mr Taylor said he had not seen a sheep in this vicinity since 1917 which is about 22 years ago. Dr Taylor lives near Baker, Nev. and has known Kauffman for some time. Aug. 17. Wm Forghurst and I have hunted over a large part of the territory around Treasury Lake and we have hunted south from Wheeler Peak for 6 or 8 miles. We followed the main divide of the Snake range as we hunted south. No sign of Mt. Sheep was seen. We hunted north of Wheeler Peak, for about 2 to 4 miles as well as up on Wheeler Mt. itself. I picked up one Mt. Sheep (Ram) skull about 5 mi. S. Wheeler peak, and one Mt. Sheep (Ewe) skull 1 or 2 mi. S. Wheeler peak and one Mt Sheep (Ram) skull (mostly horns) on the NW slope of Wheeler Peak. Yesterday Mr. Briggs the Forest supervisor for Eastern Nevada.

J.R. Alcorn 1939. Ovis. Aug 17 1939. Cleve Cr, 5000ft, White Pine Co., Nevada, said the forest service did not believe any sheep to be in the Mt. Wheeler region. He did say there possibly may [illegible] be some in the Shell Creek range and to see Mr. Alex Kolcheck who lived in [illegible] at the base of the range, we contacted Mr. Kolcheck who said he took Major Goldman who represents some museum into the Shell Cr. range & Major Goldman & party saw about 20 or more head but were unable to kill any although at reasonably close range. This was years ago, he said, and although he had not been into the back country for some years he thought there was a possibility that Mt. Sheep may still be in the area. From his cabin on Cleve Creek he pointed out the country we should go to. So we walked into an isolated spring where we found about a dozen domestic sheep (rams) but no sign of Wild Mt. Sheep.

Mr. Calloway had a mt. sheep head mounted in his house that he killed about 2 to 4 miles East of his ranch during the past five years. This mounted head was very dark in color except the nose which was much lighter. The horns were massive. It looked to me like typical Ovis canadensis and not like Ovis nelsoni from the south. At Nyala in one ranch house we saw one Mt. Sheep mounted that had been killed in the vicinity and it was pale in color & looked like Ovis nelsoni from the south. Nyala Calloway ranch are not more than 20 miles apart. We hunted the Troy Crb vicinity up to the headwaters then on up to the main divide but no mt. sheep or signs were seen. We did not stay long enough to hunt it out.

Rattlesnakes come here to hole up for the winter and before leaving in the spring to go onto the desert they stay about with parts of their body exposed to the light & seen. Perhaps they do this to become accustomed to the light after their period of hibernation. I counted thirty of them but did not kill or collect any. October 1936. On Lincoln Highway, 35 mi.

At first I thought something at a distance was making the noise, but looking down near the waters edge I saw a leopard frog that was being swallowed by a water snake. The frogs posterior end was in the garter snakes mouth and with the frog half eaten it was (the frog) uttering a pitiful sound (possibly for help) with its mouth that was sticking out of the snakes mouth.
