Koford 149 Cynomys ludovicianus June 21, 1935 Wmd Cave N.P., S. Dakota growth is taken. Or at another site watched on field. It pulled up stalks of A. am, pulling out of sheath, took a bitton two at succulent basal tip, + discarded the stalk. This repeated for many, so many cut but not eaten except at tip. Our pet "Herman" usually does not eat leaves of them, but relishes a little or two for tender white tip. // On Ward A I counted 8 grown, 4 groups, 6x1 juv. It: is probable that juv. from littin 50's to 5, when I stopped a parous 9 yesterday. These 5 (no.) juvs. with adult. Juvs. attach to sad, not mother, when she is lost? (only 10 before?) In principal expansion area 5W of Ward A I counted 13 grown, 4 now one litter of 6 at our burrow (300' W. of Ward A). May litter size has seems to be 6. // In area 2, in bottom, 3 grown + 4 juvs. (together), as before. At E. end Ward D I omit ted them in plot; 9 no. juvs. (Possibly 2 juvs. one site thin.) Two more in patch of solid Chenopodium album. // In bottom near creek led to S. of E. and Ward D, a conspicuous crater in area of Bromus japonicus with odd 2 juvs. Near us. A. am., Kappella, Corolla, Sphaerolcea, Cheno. album, Solanum, Amaranthus (Comes.). Within 10 yds. 2 other weed-appearing burrows, 4 several old burrs. in grass to N.W. At least 20 yds. of solid Bromus japonicus dominans, 1-1/2' high, separated from nearest area shelter group A. am. Photographed this! Droppings found atop 1 1/2' high boulder in open. // Are next burrows always with well-dug. mss.? // Ward A, new digging at some old burrows or reopening old wounds when burrow weathered mostly closed. At SE edge of Ward D, much death canas cut (photod). In area 50x20 yds., nearly all of about 100 seed stalks, 12-16" high, cut. // Under 1' high boulder (1 1/4" x 2') a burrow dug 6" inches deep. // Another old burrow found plugged freely. Opening (upper, old) had been about 1 1/2' diam. Nearest used burrow 50' distant. // Head of slope (N. side) Ward D had few burrows on slopes 7-15%, & more currently used above this level. Farther uphill much A. am. + Andropogon. // On Ward G, rocky area with period uphills
