Koford Cynomys ludovicianus May 8,1955 Nr.Ft. Gilling 6lo. set). No troche at any burrow where I taken (nor one or rabbit), In stonining spee. from Olbermon's See. 10, noted 07-07 all about same in molt + tester size, the token our distance of a few hundred yards where vegetation varied same. This indicate sample from a colony not have to be from one small part? Apparently molt started at corner mouth, around eye, & better. eye & can, proceeds behind on belly, then levels on dorsal surface to sacral area + thigh. Tail of sacral area bare or omitted? Some 07-07 had whitish hairs near girtle as if recent molt there. Sexes molt some time? or do 07-07 lag behind? ? May 9,1955. At colony near dump, I took a 07-4 g in traps (c). Then near N. end of colony in burrows 50 yds. apart. Burrows to 100 yds. farther N. showed sign of C.l., use this spring. Occupied burrows on slopes to about 50%, facing S.W., though old burrows on steeper slopes + an opposite slope. || At Dec. 3 horse parture, I shot an adult 07-4 saw 10+ others. Most concentrated on N. slope of 5+%. between day water reservoir & an irrigation ditch in area of about 2 acres (at least 5 in one acre at one time). || On Dec. 4 saw two in wheat field on S. side, where same trapped. I shot a 07-4 a 9 adult on flat tin bottom, unploughed, 30+ yds. from the edge of wheat field. Fair amount Agropyron smithii there, + yellow wildlife, Chrysothamnus. || Warren told me that Buckbee & Bout. gree. weirero production when clipped. Thus, clipping all plants by rodents might increase total production + net of left for cattle buy C.L. as much as otherwise. May 10,1955 Traps held 04 not spring. Took all up. Ground
