Koford 194 Cynomys ludovicianus July 29, 1955 Wind Cave M.P., S. Dak. In Ward C there is area of batten about 100 yds. long of B.ja; then about 2 A. of green with C.L. (6 grown counted) at S. end (edge colony). This batten thin in spots, not a strong barrier to C.L. At 8:30 a.m., 9/10 overcast, 5 in 1948 Ward A area, but 3 grown just W. of it, + 2 jüns. 50 yds. to S. In area S. & W. of old Ward A I counted 23, approx. 1/2 being jüns. (These areas, old Ward A, & 1950 expansion area, are separately mapped). Litt. Brown A. sm. tall (18") in Opuntia dumosa; due to protection from elements rather than C.L.? // Two caucuses on ground in colony, Ward A, + a dove. // At edge B.ja., much of it cut. Old burrows opened in edge of B.ja. nearly covered with cut stalks. // In the 3 apparent burrow wallows on Ward A, Dips. pappus now main cover. // Some wounds that King mapped 1948 now still rather small, about 6" thick. Some in 1950 invasion area now equally large. Ward B mts. are about 1 ft. thick + 6' drain. (larger area). // An old (mapped) burrow NE part of quadrat I & (King, 1955, p.56) freshly dug out as if by Badger. // In area X, where 160' transit line laid by Albert Koford, much cut B.ja. scattered, 4 reeds stripped from standing stalks (isolated plants). Also, also cut, + many culms pulled from skitho. Much Sphaeroclea cut in W. extension of Ward A. // No survivor, Area W. // Tash Chita photo, 35 mm., on Wards A+B. July 25, 1955 at 6 a.m. warm, still, 2/10 overcast. Counted loops on King's 1948 Ward A. Decided 8 grown loops there. In quadrat I & C, about 5 jüns., + some visited edge of Ward A. Another grp. of 3 jüns. in Tb, S. of Ward A. There seemed only jüns. E. of line G/H (King map, p.56). The rest of King 1950 invasion area (King, 1955, p.58), 11 grown + 3 jüns. (doubtless not all out) counted. In area S. of Ward A, about 4 + 3 grown. So, S. of Ward A 3 grown + 8 jüns., in all invasion area (S+SW+W), 17 grown + [illegible]
