Caudatus was thus seemed to be migrating through and not resident. Two Uta lizards, seen running on rocks, temp. 82°F, both were collected and preserved in 10% formalin. Arroyo Seco, 12 mi. S of Palo Verde, Imperial Co., Cal. f. Dec. 19, 1938 Made camp near bottom of Arroyo Seco, at edge brush just below gravelly plain, where creoste bush is dominant plant. Set out 35 traps at foot of creoste bushes on gravelly ground. Visited traps at 9:15 P.M. and took 2 Dipodomys (merriami?) and one Peromyscus maniculatus, which I put up for use. In had one more Dipodomys (merriami?) Dec. 20, 1938 Strained hard for about 20 min., so that water covered the foot of our tent. We hastily packed, starting when the rain started at about 4:45 A.M. Rain stopped soon so after finishing packing we walked south from camp, along edge of brush, to where some bee hives were under a shelter covered with what I think was arrow weed (Pulchra sericea). The bees were scarcely active about 7. On way down saw flock of Gambel Quail, shot at them with a .410 shotgun & 7½th shot, but only knocked feathers out

Departed about noon to look for higher camping spot. Got stuck in a wash because went through too slowly. Before leaving camp found two weevils (Curculionidae) and two beetles (Tenebrionidae) which I collected for Tillotson. Found camping place about 1 miles N of other place, still at foot of Arroyo Seco but further from cottonwoods trees. Set out 35 traps on sandy ground that was quite damp but had not been under water (flooded). Traps were put under creosote bushes, both on sandy and gravelly ground, but most were on damp sandy ground. Attempt was made to cover area thoroughly as it was somewhat isolated. The whole area was about 100 x 200 ft. Dec. 21, 1938 - Caught one Dipodomys (merriami) and one Perognathus. Will leave traps in same places tonight & try peanut butter for bait in place of rolled oats. Shot a mockingbird this morning. Heard coyotes howling last night also numerous great horned owls and some screech owls,

North (copy) epn 4 Arroyo Seco, 12 mi. S of Palo Verde, Imperial Co., Cal. P. Dec. 21/1958 Saw flock of Gambel quail this morning. Temp. 43° F and Koford shot one with 12 gauge shot gun at 6:45 AM. They broke up into pairs after being shot at. There was no rain this morning but a cold S wind is blowing. Mosquitoes were numerous last night. After lunch Koford and I walked down to edge of Colorado River - vegetation was as follows - first, that is nearest to camp was belt of mesquite which gave way to screwbean closer to their river where it seemed to moister, scattered sometimes in the screwbean but usually closer to the river were cottonwood trees, after the screwbeans, and forming a very dense growth close to the river and was arrowweed (Pulchea ericea sericea) and at the edge of the river some willows and many cottonwoods. We found an open space 2 or 3 hundred yards long and about 75 or 100 yds wide that had grass and was flooded. The area was flooded at the time and no attempt was made to identify the grass. We walked upstream along the edge of the bank until opposite the N side of the arroyo and then back in towards it.

North 5 (copy) CPA Arroyo Seco, 12 mi. S of Palo Verde, Imperia Co., Calif. Dec. 21, 1938 All the way to the river, we walked in mud, also all the way back. We talked to a cattle tender or caretaker of the fence off land and he said that it took several men on horseback with the aid of dogs 3 weeks to round about 150 cattle out of the brush we had just come through. He also said that the whole river bottom flooded at every heavy rain which accounted for the extreme muddy & wet conditions we found. This agreed with our experience on Dec. 20, 1938 when a 20 or 30 min. rain put about one foot of water in a wash near our camp. We were told by the cattle tender that the deer stayed in the thick brush but some forced out by water into the gravelly plain that is cut deeply by many ravines or small canyos. The canyos near our camp had many mesquite trees and some Palo Verde trees in them all of which seemed to lean "down stream". Dec. 22, 1938 - Traps in same place as last night. Caught 49° F at one Cerognathus with broken tail, probably 6:45 A.M. one that sprung trap early in evening; nothing else was taken although 4 traps had bait gone. Last night picked

Birds seem to be quiet as compared to yesterday, due possibly to rain last night and clouds this morning that have not cleared up by 8:30 AM. Phainopeplas are only ones that are giving call notes & those not very frequently. I shot a ♀ Phainopepla this morning and put up the skin. While turning over boards around camp, which was at the site of an old bee shelter like the one seen at the last camp, I found 4 collected 4 Uta lizards. They were very torpid but could move around, 2 flitted quite rapidly. They seem in good condition and probably are active during the day when the temperature is high enough. One was very pale and seemed spotted rather than striped. The others are quite dark. Two have regenerated tails. There are many small gray birds about the size & appearance of goshawk proteotethers, and a few Kinglets, both frequent mesquite and creosote bush mainly. Coyotes were heard howling in the direction of the river at about 7:45 AM. Broke camp about 3:30 PM with cold N

North 7 (copy) epn Anicoyo Seco, 12 mi. S of Palo Verde, Imperial Co., Calif. Dec. 22, 1938 wind blowing. Birds were quite and sky clouded. Made camp in strong N wind about 1&mi. N of Oglby, Imperial Co., Calif. Ground covered with small rocks, with some soil beneath, vegetation was principally creosote bush with some cactus. Camp was at edge of wash with mesquite and palo verde the main trees in it. Set out 20 snap traps in the dark along a shallow drainage groove where there were a few creosote bushes & some very low, grey bushes. Set traps at foot of brushes. Went to bed at 7:30 pm with cold N wind blowing & sky cloudy. Dec. 23, 1938 Sky cleared up during night but strong cold wind blowing in morning. Caught one Resognethus at foot of dead scrubby tree. Only saw one bird & that was flying over so could not identify it. Broke camp & drove to Oglby then to Yuma, Arizones when stocked up with food. Agriculture inspectors did not inspect us as we were coming right back to California. Drove west along highway U.S. 80 & then branched to Calif. 98, towards Calexico, Imperial Co., Calif. Made camp about 1&mi. E of Calexico about 1:00 pm., on sandy

North 8 (copy) apr 1/2 mi. E of Calexico, Imperial Co., Calif. Dec. 23, 1938 ground with fine gravel in it, with creosote bushes spaced about 30-50 ft apart, the only vegetation. The sand is fine enough to drift. Set out 36 snap traps, near and under creosote bushes and out in the open. Set them about 20 paces apart. Caught a house mouse (Mus musculus) before going to bed. Nearest dwelling is at a group of house trailers of workers of a construction job - 1/2 mile or a mile away. XX Dec. 24, 1938 - Kofford caught a kit fox in a stal 490 F at trap baited with mouse bodies. 6:45 A.M. I walked in rolling sand about 1/2 mile NE of camp & found what looked like Dipodomys tracks but they were not numerous and appeared to wander far so that a few rats could make a lot of tracks. Saw a thrasher, appeared to be (Toxostoma econtei) and some other birds I could not identify - had long tail & relatively short wings, tails carried high when on ground but in air bird look like black- bird in outline. Color was grey with a dark streak on each side of breast. Have identified bird just described as Sage sparrow (Amphispiza nevadensis)

North 9 (Copy) (C.P.A.) Mmi. E of Calexico, Imperial Co., Calif. by one D shot. Dec. 24/1938. Moved camp west on high 98 toward few Calexico about 2 miles where found Dipodomys tracks on sand. I did not set any traps but only took 4 Dipodomys and one Thomomys (gopher) or after putting them up we moved camp about 1 mile west where found many Dipodomys Dec. 25/1938 tracks. I did not set any traps as was too tired. Koford caught on Dipodomys before going to bed. Dec. 26/1938. This camp is on rather rolling ground with hillocks covered with mesquite numerous nearly all of these hillocks have Testoma (woodrat) bones on them. There is some erbsote brush present also many low greybacks about 1-1/2 or 2 ft. high that appear to be a sagebrush and perhaps some (Atriplex?). One of these bushes has every prickly fruit which the rat tracks would indicate that the rats are eating. Nothing else was caught by Koford last night. This morning I found 2 freshly dug kit fox holes where I made a steel trap set beside one of them. One had bird feathers & part of a wing in it and appears to have been a G cache as the feathers were not fresh. Baited trap with

North 10 (copy) spn 14 mi. E of Calexico, Imperial Co., Calif. Dec. 26, 1938 piece of jackrabbit I shot with .22 rifle this morning. Saw two thrashers (T. lecontei) and a mouse I could not identify also many small grey birds that looked like junctatches also juncos. Set 36 snap traps half which I covered partially with sand & rest uncovered, all baited with rolled oats. Also set 6 rat traps on hillocks for woodrats and made another kit for set with steel traps. In evening heard quite a few doves that seemed to be going to roost in the mesquite on the hillocks also saw what I think was a Say phobbe. Dec. 27, 1938 Caught 2 Dipodomys (merriami?) & Lyford cought a jackrabbit (in a steel trap) and a Dipo also later a thrasher (T. lecontei) in steel trap, I took 2 DeSorna & Lyford 3, they were all except one infected with Botwarbles (Cuterbra sp). I shot an immature white-crowned sparrow but it was moulting badly & feathers came out at the slightest touch, so I did not put it up. Broke camp at 3:30 p.m. & went through Calexico where mailed some post cards, and bought some supplies - made camp for night about 14 miles W of Calexico, about directly N of W end of Signal Tnt.

North (copy) (cpa) 11 Country is rolling but fairly flat. Sand is white or nearly white. Borobush that I think are a type of sagebrush are the main vegetation with some smoke trees (Parosila) and one mesquite tree in a wash near camp. Set 23 snaptraps and partially covered them with sand. Dec. 28, 1938 Caught 2 Dipodomys and Koford caught a Dipodomys deserti and a kit fox. There are many large flocks of larks present. Set 6 gopher traps in morning and picked them up just before leaving. Caught one gopher. Collected several Tenebrionids for Lilloo. Broke camp and drove westward towards Mt. Springs on this same road which goes west from Mt. Signal (town) across desert few miles N of Mexican border. Tried to find type locality of Peromyscus crinitus stephensi described by Griswoll as "3 miles east of Mt. Spring, Imperial Co., Calif." but that would put you in the middle of the Mts. & not at the lowest water on wagon road near eastern base of Coast range" which is true location as given by describer of species, as it would not

North 12 (copy) epn Dec. 28, 1958 have been possible to take wagon over country 3 miles east of Mt. Spring with any vestige of ease; so that it is my opinion that the wagon road ran through the canyon that Mt. Springs join and that the lowest water, at eastern base of the coast range, is near near the east end of the canyon and in the week dry when we saw it, that is at the bottom of the canyon. This would place the type locality of Peromyscus crinitus stephensi stephensi NE of Mt. Springs and also I think that it would be more than 3 miles from Mt. Springs. This is to be investigated when we return to Berkeley. In our search for possible wagon road we finally wound up sometime near the Petrified forest, south and a little west of Coyote Well, Imperial Co., Calif., and we think in Mexico as we passed a sign that warned people entering the United States to report to customs officials. We went a mile or more passed this sign which was on a road supposedly to the Petrified forest, along the east base of the Coast ranges. We stopped

North 13 (copy) opn 6 mi S and 3 km E of Mt. Springs, in Mexico. Dec. 28, 1938 at a deep wide wash, about 60 ft deep or a little more and several hundred feet across. This wash was just west of a small range of hills and east of the coast ranges. We followed tire tracks in the sand along the east base of the coast ranges until the sand became too soft. This put us at the base of a small hill at the foot of the coast ranges where we directly E or a little NE of our camp, could see, Mt. Signal, (in Mexico), through the low place in a "saddle" made by the small hills east of the coast just described, which was several hundred yards east of our camp. With 8x30 binoculars, we could see a road which we think is probably the road from Mexicali, Mexico to Tecate, Mexico or a branch of that road to Jacumba, Mexico. We walked about 2 or 3 miles towards it but then saw no connection between it and the tire tracks we were following. We made no other attempt to get to this road which would probable have been possible by crossing the wash east of our camp at a place NE of camp. The true location of this camp will be

A low greyish bush is the predominant vegetation with some creosote bush & a few varied cactus. There is also a type of grass that seems to grow in small bunches but does not look like or grow like a typical bunch grass. There are quite a few fresh gopher mounds scattered on the lower part of the slope that comes down from the hill.

Dec. 29, 1938 I did not set any traps last night but Kford set mine in addition to his, and caught took 4 Dipodomys, 3 Perognathus, and 2 Peromyscus that appear to be P erinitius. I set 5 gopher sets this morning and took 3 gophers during the morning, which are quite small compared to those taken east of Calexico, but are about the same color. I put up gopher taken by me yesterday morning 14 mi west of Calexico, 3 Perognathus, and 2 Dips, also a thrasher taken in Kofords steel trap east of Calexico on Dec. 27, 1938. Set out 31 snap traps - lost 5 somewhere - , or top of hill west of camp, on rocky ground. Dec. 30, 1938 Caught 3 Dips and 2 Peromyscus but no more gophers. Kford made two double gopher sets but did not catch anything, although the traps of one set were torn apart and one trap I found about 15 ft. away but other could not be found. Last night was fairly warm in spite of a gentle N wind blowing. Kford took 5 Peromyscus (crinitus ?) on westside hill I trapped on, but down at the bottom of a small canyon.

North 16 (copy) CP7 4 mi. N of Warrens Well, San Bernardino Co., Calif. Dec. 30, 1938 Have not seen any birds but heard a thrasher and some other birds that give a call note like the tscep of a white-crowned sparrow. Moved camp - went N through Imperial and Brawley and stopped just off highway U.S. 99 N of Brawley a few miles. Dec. 31, 1938 Visited Salton Sea Beach and saw Willets, Godwits and some unidentified gulls and a sand piper. Made camp about 4 mi. N of Warrens Well, San Bernardino Co., Calif. among large rocks with many junipers and tree yuccas present. There were many low shrubs I could not identify that formed rather a dense cover. Jan. 1, 1939 Caught Dectoma (Dipodaga) Promopus and 2 gophers here. There were quite a few Uta lizards active during the day I could not catch them by hand but Koford shot one "gently" with a .22 revolver. They all showed a bright reddish orange spot just down these eye which showed up very well as the lizards moved around. The soil here was dark and composed of decomposed granite and vegetable matter. The surface soil was light but beneath it was quite dark.

North 17 (copy) epa Jan. 1, 1939 There were many woodrat nest, present with one in nearly every large rock crevice . Saw one Sage sparrow but no other birds. Jan. 2, 1939 Moved camp - went by Old Woman Well and on into Victorville, which was closed as far as stores were concerned. We are out of # 22 wire and 50 some # 18 and # 24. Went SW 5W on highway 66 looking for pinyon pines Dr. Hall said there supposed to be about 10 mi. S of Victorville. Went as far as Cajon Pass but did not find any so took Road to Hesperia which runs from east from about 10 miles SW of Victorville on highway 66. Went through Hesperia which is 9 mi. S of Victorville but did not find any pinyon pines present further on down road to Lake Arrowhead which runs SSE of from Hesperia, and camped at edge of Molare river about 8 mi. SSE of Hesperia, San Bernardino Co. This distance is as the crow flies - we were just barely N of the San Bernardino National Forest. Jan. 3, 1939 Took 10 Dipodonyx (melaensis?) and 26 deg F at 7:00 AM 2 Peromyscus in 50 traps (All South & North). Traps were set among pinyons which were rather thickly scattered in a

North 18 (copy) epn Jan. 3, 1939 low unidentified buck. There are no yuccas on this (S.) side of river but across the river or S facing hillside there are many yucca whipplii growing. The ground is very sandy with some very coarse sand and small gravel. Soil is the darkest we have trapped on and the mammals are also quite dark, the Dipodomys and gophers especially. Jan. 4, 1939 190 F 6:45 A.M. Last night we took 9 Dipodomys and 2 Oxychronyx and 1 Perognathus maniculatus. Shot a pipit on the sand at edge of river yesterday, No. 255 epn catalogue. There are few birds here, saw strike or flock yesterday and Juncos today also heard Great Horned owls at night. Scared a few quail up from foot trees in morning. Saw flock of western bluebirds this morning. Moved camp up road to Lake Arrowhead to place about 4 miles N of lake Arrowhead and camped at a public campground called "Toll Road Public Camp Ground". This was near summit of mts. Koford set 25 traps but I did not as I wanted to hunt some birds in the morning. Camp was among tall ponderosa pines with Ceanothus about 200 ft from camp. Saw Steller jays, a chickadee, a slender billed nuthatch and a

North 19 (copy) epn Jan. 4/1839 Hairy woodpecker - distinguished from downy woodpecker by its call. A large flock of juncos was present in the camp area also. Jan.5/1939 Burke can Koford caught a Dipalomyss (molavensis), 1 Perognathus, 1 Peromyscus (boylii or truei?), 2 Rectoma and a gopher. He set his traps among rocks and at edge of brush. Before leaving while I was packing Koford shot a ? white-headed woodpecker. This morning and yesterday I heard California woodpeckers (Melanerpes formicivorus bairdi) calling but did not see any. A few robins were present in the trees around the camp also. We broke camp as soon as possible due to extremely threatening weather and drove west towards Lake Arrowhead. The road had been scraped clean of snow, but it was still very icy and treacherous in places. We got into fog at Lake Arrowhead and did not get out until nearly at the bottom of the grade down to San Bernardino. We saw numerous coots (mud hens) on Lake Arrowhead as we drove by. Due to heavy rains which we

North (copy) epn (Jan. 5, 1939 copy) epn (Jan 20, 1939 original) epn Jan. 5, 1939 had to drive in from San Bernardino to Los Angeles, the road was flooded in many places at one time reaching the running boards of the car. Jan. 20, 1939 I have looked up data on the type locality of Peromyscus crinitus stephensi that we looked for, Dec. 28, '38, without finding. The type specimen was taken, May 8, 1894 - quote, "among granite boulders at the first water in the canyon through which the wagon road crosses the Coast Range Mountains by way of Mountain Spring, in San Diego County, California, at the east base of the mountains," unquote. The for. giving description is taken from "Smithsonian Institution, United States National Museum," bulletin 56 of the year 1907 and written by Edgar Alexander Mearns, M.D. Major and Surgeon, U.S. Army. In giving his itinerary and [illegible] description of flora, he states, p. 131, that from May 7 to 9, 1894 his party was camped at station No. 84, which was quote "Eastern base of the Coast Range Mountains, San Diego County, California. This station was

North 21 (original) copy Jan. 29/1939 at the lowest water in the canyon through which the San Diego wagon road passes about 8 kilometers (5 miles) north of Monument No. 230, 129 kilometers (81 miles) west of the Colorado River, and 98 kilometers (60 miles) east of the Pacific Ocean. Altitude, 560 meters (1,837 feet);" my note. Station No. 83 was at Coyote Well which was, I think, the present site of the present Coyote Wells, Imperial Co., Calif. since he gives that location as: "13 kilometers (8 miles) north of Monument No. 229, 127 kilometers (79 miles) west of the Colorado River and 100 kilometers (66 miles) east of the Pacific Ocean. Altitude 100 meters (328 feet)." By checking on maps that show monuments I decided that this agreed with the present Coyote Wells. From Station No. 84, Mearns says that they moved "up the slope to Mt Spring"; from this I judged the two camps to be in the same canyon. Checking on maps having monuments showed Mearns' Mt. Spring to be the site of the present Mt. Springs, Imperial Co., Calif. By drawing triangles and using

North 22 (original) opn Jan 29,18 distances from monuments given by Mearns that I have calculated that the type locality of Peromyscus erinitus speatophani should X is 3.6 miles NE of Mt. Springs, Imperial Co., Calif., or about 4.2 miles SW of Coyote Wells,Imperial Co., California and at an altitude of 1,837 ft. These distances" as the crow flies). At the time I was looking for the type locality, there was no water in the wash however a search might have found some and since I was driving a car, I could not look for water. I did not have this description with me either. I believe this type locality to be near the mouth of the canyon and when looking for this place, I suggest that distances should be measured "as the crow flies," and not along the road by automobile speeds speedometer. I checked distance between the present site of Coyote Wells and Mt. Springs, at a Shell Oil Co."road map and found it to be roughly 8 miles this agrees with the distances as computed from Mearns' data. I also suggest

North 23 (original) epn Jan 29, 1939. that persons looking for this type locality, if possible, take with them an altimeter as the land slopes gently at first and then takes a sharper grade, but the bottom of the canyon which [illegible] was in at the time has a gradual slope. If further data is wanted concerning the above material I refer you to "Mammals of the Mexican Boundary" Bulletin #56 of Smithsonian Institute, United States National Museum" by Edgar Alexander [illegible].

North (copy) CPN Uta stansburiana Dec. 19, 1938- Two were seen sunning on rocks. Were very active. Temperature was 82° F. They were caught and preserved in 10% formalin. This was at our camp in the Palo Verde Mts. about 8 mi. S of Palo Verde, Imperial Co., Calif. Dec. 22, 1938- Arroyo Seco, 1/2 mi S of Palo Verde Imperial Co., Calif. - Four were found, and collected, under boards. They were on gravelly ground above flood point. Creosote Bush was main vegetation, with mesquite and Palo Verde nearby in the washes. There were a few larger rocks around but no boulders. Two of them had regenerated tails. All were very torpid but could run quite rapidly if given the opportunity and stimulus. They were preserved in 10% formalin. Jan. 1, 1939- 4 mi N of Warrens Well, San Bernardino Co., Calif. - There are quite a few Utas present here but I have not been able to catch any due to the great amount of small shrubs present. All the Utas here seem to have a bright reddish-orange spot over the eye. This shows up very well on the live lizards. Koford shot a Uta "gently" with a .22 revolver to day - # No. 262 CPA catalogue.

(copy) cpn Dipodomys (merriami?) Dec. 30, 1938 - that seemed too large for merriami I think they were deserti because many four traps would be drag several ft when set. All of the Dipo tracks seemed to concentrate on the lee side of sand dunes, on the lee side of small grey bushes that had a very prickly fruit. This concentrate of tracks on the lee side I think may have been due to wind blowing the fruits towards the lee side where I could usually find small pills of the burrs. These fruits had much the same appearance of star thistle fruits (Centarea) except that the spines were not as long and much broader at the base. There were many small holes an inch or two deep, some of them with Dipo tracks around them. I dug at some places where the soil was disturbed, as if a beetle had dug in, and found a small brown beetle at the bottom. I collected several of these and have given them to Mr. R.F. Lillston. Other places of soil disturbance proved to be places where small plants were breaking through the surface

North (copy) epn 3. Dipodomys (Gmeriani?) Dec. 30, 1938 - so that the Dipodomys may have been digging either for the recently germinate seed or for the beetles. In several of the Dipods I found fruits of the small grey bush & so am sure that this is used for food. I also have noted that no tracks ever found or Dipodomys caught when this bush was not present. At our camp 16 mi. E of Calipico, there were many rather large holes dug in mounds at the foot of creosot bush and a, green shrub that had no leaves and had somewhat the appearance of Scotch broom. I dug into one of these and found many burrs, of the low grey bush, in the burrow passage, they may have been blown in by the wind but I think were carried in by Dipodomys. Here, at our camp SSE of Mt. Springs, Imperial Co., the Dipodomys are the palset we have caught yet, the sand is also the lightest color we have stopped on to date. Here I have taken slipodomys on sandy and rocky ground but nearly always,

Here N of Warrens Well, San Bernardino Co., I took 2 Dipodomys among low shrubs, with many junipers and tree yuccas present. Soil is rather coarse and composed of decomposed granite and mold from leaves of the rather dense vegetation, which was never more than 10 or 15 ft. between bushes.

North (copy) EPN Perognathus Arroyo Seco, Imperial Co., Calif. Dec. 21, 1938 One taken on sandy ground just above flooding level, with creosote bush the only vegetation. Dec. 22, 1938 - One taken on sandy ground in same area as last night. Dec. 23, 1938 - One taken on ground covered with small rocks and some dark soil beneath. This ground appeared to be volcanic. Dec. 29, 1938 - 3 taken on rocky slope and on flat at top of slope. Only vegetation is a low grey bush - possibly (Artemisia) and another low bush with many spines, some creosote bush was present also. All vegetation was well scattered. Jan. 5, 1939 - Koford took one at our camp 4 mi. N of Lake Arrowhead, San Bernardino Co., Calif.

North (original) epn Neotoma Arrow Seco, 12 mi. S of Palo Verde, Imperial Co., Calif. Dec. 27, 1938 - Koford took a young Neotoma under a mesquite tree near a wash. I have not seen any neos probably because I don't know where to look. Koford saw a small animal that he said was either a woodrat or a ground squirrel. 14 mi. E of Calipco, Imperial Co., California. Dec. 26, 1938 - There are many woodrat droppings outside. Just at appear to be old nest under mesquite on hillocks that rise up to 10 ft. in some cases more. I have set 6 rat traps when I found the freshest droppings or freshly cut mesquite leaves. I have not seen any tracks that I thought were Neotoma out on the sand away from the hillocks. Dec. 27, 1938 - I took two rats & lost a trap (carried away) and Koford caught 3 rats. All of Kofords are infected with one or two bot warbles (Cuterebra) either under the neck or on the chest. Mine of mine had a very small warble that had not broken through to the outside surface, and the other was clean. The rats did not

North 2 (original) epx Neotoma 14 mi. E of Calexico, Imperial Co., California. Dec. 27, 1938 - seem to be in poor condition physically due to the hot winters. Jan. 1, 1939 - 4 mi. N of Warrens Well, San Bernardino Co., Calif. - Here there are many large granite rocks and piles of granite, which have cavities and crevices in them. Nearly all of such places are occupied by woodrats as evidenced by droppings and trapping. The rats here seem to be eating juniper berries to a great extent. The Peromyscus taken seem to be somewhat connected with Neotomas as they are caught nearly always, close to Neotoma nests. Jan. 3, 1939 - 8 mi. SSE of Hesperia, San Bernardino Co., Calif. Here there are piles of sticks & freshly cut juniper at the foot of many of the juniper trees that I are woodrat nests but we have only been able to catch one Neotoma.
