T. Cole 1957 Lemming twinning 10 June - cent. Spring. Predation does look like it will be less this year, and these animals have much better cover, anyway, than a comparable population at Barrow would have at a similar stage of phenology. The larger and earlier growing reason at their weight also favors the lemmings because of its effect on vegetative regeneration. The virtual lack of owls and the moderate numbers of jaegers present - even if they preyed well, would have little effect on the lemming population. 12 June. Caught 2 mares by scent and saw a couple of others while surveying transects. Dug out some of the tunnels & holes in the trow.

From the looks of the ground, old clefting, etc., the animals must have been common in the dry troughs during winter, and when the melt off came, they had to move up on higher ground. So the high cuttiss are more supporting a population that was occupying a considerably larger total area. This may
