He stated that in the fields surrounding our headquarters there had been 90 acres of alfalfa, and that gophers (Thomomys) were known to have occurred here then. He spoke of ringtail cats (Bassariscus) as occurring on the Arizona side of the River, but not on the Nevada side. Most of his observations seemed sound and logical to me, but I doubted his assertion that ringtail cats quite frequently killed young pigs. Jan. 15, 1934. Cooked and washed dishes. When Dr. Benora and Fitch left for Middles in the truck I rode up with them to the farther end of my trap- line. On leaving the car, I jumped a jack- rabbit (Lepus californicus) at the lower border of the creosote brush, shot at it and missed. At my first trap I found a grey fox (Urocyon inebargentus) in the trap. I shot it with the .410 ga., and went to look at my other traps in the near vicinity. In one I found a bobcat (Lynx rufus). It was quite large, by com- parison with thirty or more which I have observed in similar situations, and was almost lacking in black markings. I shot it with the .410 ga. It did not expire, so I shot it again from a distance of 15 feet.
