E.M.Brock 1957 Journal July 16 Barrow, Northern Alaska "prior activity" all old clippings found loose on the ground not just standing, old clippings. For all other transects prior activity was noted by old droppings and/or cut grass with a shot (1-2cm) dead area at the clipped end. Today (July 16) I checked lines I, II and VII for prior clipping activity and corrected them accordingly on the utilization records. The new litters of lemmings from July 13 was checked and a little data recorded (see "Lemming") July 17 Transect II A + IV B checked once again in morning and evening; nothing has yet been taken in line IV A but another lemming was caught in line IV B. A few lemmings were processed and a ground squirrel skin prepared. Wainright lemmings were processed. July 18 Transects IV A + IV B checked in morning and evening, and still no lemmings have been caught in transect IV A; therefore traps were left out. Lemmings were processed. Heads of 100 traps were smeared to ready traps.
