R Dixon 1952 Feb. 10 15 mi. W Bastrop, 600 ft., Bastrop Co., Texas OVERCAST throughout morning. Wind generally southerly rather strong. I spent the period from 8:15 - 10:45 in area along stream W of road on Young property completing my map. After 11:00 I worked downstream to main creek also mapping. I returned to camp at 12:50. No Arvica heard during entire morning. During mid-afternoon I ran a 200-foot transect of woody vegetation in area S of road where Arvica of magnitude 2 of 1951 foraged. The elms were more widely spaced than I had recalled earlier. I found the following numbers of individuals in a 200-foot line running E by compass from a hack- berry in shallow brook area: Prosopis /2 Opuntia 8 Berberis trifoliatum 7 Celtis sp. 3 Prickly pear (KD 476) 2 2 ?Diospyros 1 Ulmus crassifolia 1 W || 2 | 4 | 1 | 4 | 12 5 | 3 || 5 | 1 | 1 | 3 | 4 | 9 | 4
