Koford 200 Cynomys ludovicianus August August 31/1955 Nr. Cache, Okla. alcohol flat. Main food-over town was a flashy 3" plant, [illegible] like, narrow leaves, rattling at tips. I did not eat any of this to be eaten by C.l. Many mesquite seedlings a few inches high. Tips & leaves of many seemed to have been nibbled, probably by C.l. Now from 1' to 5' tall. C.l. eliminate? - perhaps eat in winter, a eat seed. Other common foods: prostrate Euphorbia (aspid or mammillata?), Oenothera (graecizans?) (especially munda.), Aban dum portulacum (green; some in flower), Phytolacca, Crotan, Amar, Heliotropium (huge, 1/2' across, on mts.), Phleum (pseudocarpi?), Oster [illegible] (possibly called woody Euphorbia or [illegible]), nod [illegible] (slopes species), much Hoffmannseggia Schottiana. Large patches Bla 1/2" tall. Aristida occasionally; not large solid stands. Many ants. No cattle present apparently (Sporobolus, etc., otherwise would be grazed short). Some burrows on naked soil where heavily water washed. Many C.l. seen (6+ /A?). New burrows in nearly pure Sair 4" tall. Some abandoned mts., had much Portulaca, Sair, Euphorbia on them. Many wounds at low mesquite trees so soil round part bare, many holes alongside base trunks. Many trees with 3' deep ditch around base 1/2 to 3/4 of the way, evidently dug by C.l. (dropping?) (for food?). In pure Sair, flow burrows, the grass shot. Apparently favor bare areas for burrows as 8" in one bare spot had two spacing of 4 yds. only. Many handsome symmetrical 4' tall crests. Out of mesquite, above most burrows, they contained up on E. slope (possibly 10 %) where much dead Linum, & Bla, Aristida, Asa, [illegible]. Vegetation in state 30' outside peripheral burrows (Little no wounds); 4/10' farther out is 1 1/2' tall (this uplope side). Soil a
