Koford 308 Cynomyx ludovicianus October 19, 1955 NW Weld G, 6lo. Bod of Bgr this yr. (Murphy has seen 1940-1919. Range about same now another, but poor in drought of 1930's & drought of last few years). Murphy had never seen or heard of a black-footed ferret. // Another invaded area was a bottom only 100 yds. wide where Bgr main vegetation. This paired this year for first time, but at least 10 c.l. remain. Small colony. Perhaps 3A uptown canyon, bordered by steeper slope. // Another invaded area, on a 2-5% slope where Bgr dominant. Many burrows, but paired (1953 invasion too). This 300 yds. from a wind- will, about 1/2 mile E. of Bleara on U.P. railroad. // One of invaded areas in NE¼ of Sec. 12, T 12 N R 67 W, in Wyop- ing, 4½ miles from main large town W. of Carr. // 2 areas had new towns 1953, about 2 mi. from Carr colony (most probable source). // To west of highway 07, 3 towns at sheep camps. About 1 mi. from road remnants of a few dozen holes on 10% slope where thin Bgr roam (30% ground cover), 100 yds. from sheep shed, 200 yds. from edge reservoir. A similar one said to be at another sheep camp, close to buildings & bedding ground. At one still active at Brown Plow (T 12 N, R 68 W, S 28), the second there times. Another at Lower Jack camp, near Tony Romanos place; 4 near Bulge Camp (T 10 N, R 68 W). // In general few dogs left & repeated poisoning eliminating these. Total extermination is the goal. // Another town, new, paired this year, in SW¼ of Sec. 18, T 11 N, R 67 W. I visited this one. About 50 burrows in 4A. No sign of dogs now pre-
