Koford 307 Cynomys leidovicius October 18/1955 CPER, Weld Co., Colo. On an arm, over knoll just N. of town (another Mr. Carr as eagle now probable predator on C.L.). At 4:15 I saw a Cotteler lying stretched on ground 10' from burrow near 6W25. It was 36" long, stomach empty. At 4 p.m. I shot one (188) near 185 1 W (quadrat A1). At 4:20 shot another (189), 10 yds NE of of 18W85 (mid). Green Verbena bract. common in bottom. Solanum rotot. seen in seed then but apparently not eaten. October 19/1955 Terry Ranch, NW Weld Co., Colo. Spent 2½ hours with Mr. Murphy of Warner Live Stock Co. looking at present & former C.L. town sites. Range used by cattle summer, sheep winter. Dominant grass blue grass, the same Bda in bottoms, 4 conspicuous Asa or Stipa comata some riter (Stipa seeda weak into sheep meat; undesirable on sheep range, but excellent early feed for sheep & cattle). Range in general in fair con- dition, I judged, 4 greener than CPER. // One site invaded & about 12 burrows dug in 1953. This near a sheep conal (100 yds.) on gentle slope where much Big turf & much Opuntia (NW¼ of Sec. 26, T 12R67W). This was pounded '53. Site 2 miles from a large town 3 mi. N. of Carr, mainly in Sec. 3 (T11R67W). Visited site of this Town, about 2 sections in extent. Only one C.L. seen. Pounded for last 3 years by Crouch. Vegetation generally Bigrass than & Asa On gentle long slope going out to S. from Hills. Burrows widely spaced. Formerly many deep & little vegetation left (drought '52 to '54). Opuntia some
