Koford 205 Cynomys ludovicianus September 3/1955 Canadian, Texas said there seemed to be no more C.L. than before, but that they were spread over a larger area. ] Mesquite favors C.L.? Possibly seedlings +/or seeds are winter food. Cattle are shod, rub at trees, make wallows near, & water stands in wallows. This cattle use seems to shut grass, has ground weeds, & perhaps amount of succulent food for C.L. Nr. Wellington Colorado September 4, 1955 Burney Crawford, game warden, showed me that "Charlie," his pet rat, was reserve at Wellington, had disappeared, & it seemed that many flower locari in area when they had been fed. Spread out? Shot? He said he had trapped an occasional weasel in vicinity; thought possibly one got Charlie. September 7, 1955 Arrived Wellington, presume colony 8:45a.m. N/o overcast, calm, warm.
