July 30/1955 In general, when now much Bija or slopes less than 15%, if not so flat a lawn or to be low high water table, seems to be excellent terrain for C.l. (proper soil texture, climate). These areas stand out clearly (brown) at this season. // Brier Flats col. any spanned. 100 yds. E. road, running Bgr, butivan Bija, Acm, Sphaerules (four weeks).
