Brode 1937 June 29 In the early morning check on the old portion of the trapline (13 traps) only one Peromyscus maniculatus was found. The extension of the line (set last night) yielded [illegible], one at about 7450 ft elevation and one at 7600 ft. elevation, 1 Dipodomys lucogenys and nine Peromyscus maniculatus half of these were immature. Total traps set out 52; traps with specimens 12; Traps springing 5: Traps not springing but with bait missing 5. Large numbers of ants were along the trail and on some specimens there were red and black (large) ants and on some specimens there was a smaller ant that was a uniform light amber color- 1 AT 4 PM went by car with Hall and Palmer by road northward west into Mason Valley. The first collecting station was in an area at Mason Valley 12 mi. E of Wellington, Lyon Co., New Mexico, 5000 ft. Here I set out 48 traps in Atriplex, Sarcobatus, and a species of Chrysostemmus. I took a horned toad while setting trap and whip tailed lizard was seen.
