Koford 325 Cynomys ludovicianus December 21, 1955 Nr. Ft. Collins, Colo. about 1 p.m. visited Spring Canyon Dam colony. Saw 3 dogs out. One 07 (190) in trap 17. No others spring & no sign of use burrow since yesterday. Set 4 new traps no 14 total out. Apparently Verbascum and Xanthium seem to have grown little this year, the used or food here last winter. Outside of dog area many dry sudstella Bgr, the few inside. Restining of cut-off dry shea still in place - does sitting a browsing it prevent blaring? Not improbable, thinks Don Harvey of canyon dept., if so even cutting shea economical as compared to repairing fences, 11/7/90 judged free. dry tooth wear (more worn than youngest tho), & wore fat; no scrotal pigment; 950 gms.; about half stem. eat. gum pulviment leaves of fall a browse; only 25% green, including Beta stolane, old day. December 22, 1955. At same colony took 07/191 from traps no. 5 and line transit (Parker) at 1 p.m. Another trap (#14) spring. Pullled off foot of dog in trap near at pass near 5.and colony. It held so hard lost foot rather than grips. 11 set 1 additional trap. No activity at most holes when traps set, so prob- ably all not out every good warm day. Only 07/191 out? Tiny falls, mostly Sphaeralea(? & Ceniza ?) about 1/8 to 1/2" tall, common, but < 1% of vegetation. Apparently Sphaeralea main food in 07/90, the grew gross present. Buttercup & Chrysothamnus both have green herbage, but latter got browsed short by cattle. Set 1 was trap no 15 set (left 2 p.m.). 11 07/191 stomach full, 60 gms., & contained 50% dry grass, probably Beta & stolane, but about 25% green falls, apparently Sphaeralea. No odor,
