Koford Cynomys ludovicianus January 29, 1955. Nr. Loveland, Colorado. found about 30 burrows on W. side of a streambed. There formerly level grounds. Cover of Bouteloua gracilis (sparser between four inches to a foot) and much low Chypro- thamnus. Slight slope. Several burrows had been dug out by badgers. Paws appeared to be active - cobble surface mounds; no fresh droppings. I did not visit NE corner 28.19 where mice pained some. || The Jordan ranch showed extreme depletion of forage in area of C.L. burrows. No bedding at all for many years. The active colony way down had no grazing last year. || Some burrows at Jordan's contained mounds of loose shale flakes, about 3/16" thick & up to 1 1/4" long maximum; pure shale, no fine soil mixed. Some other mounds contained rocks up to half-foot size; apparently C.L. dug them up. January 29, 1955. NW Weld Co., Colo. Near Rockport on C.C. Aces Ranch I saw 2 out, about 100 yds. NW of corral, about 11 a.m. Overcast, mod. wind, & about 40°F. This area heavily overgrazed - only widely separated local parts Buchloë in most of area. I searched large town on Brange's Dec. 33 but saw no C.L. Some luck on Dec. 22 in C.P.E. R. This last appears to have been cleared out without knowledge of Jim Lawrence (lessee) or Klipple (by O'neill?). || I looked at burrows & mounds on S. side road 4 mi. W. of Pierce. Saw no C.L. a traler. Man living across road, 10 yr. resident, said this persisted 2 yrs. ago (53?) and no dogs left he thought. This land very heavily overgrazed. Soil silty & dark grey & with
