Maclean 1968 Journal 4 June) and P. fulicarius were very conspicuous. Collected 2 pectorals and 2 red-backs before coming in. Weather was again comfortably warm without much wind. 5 June Barrow, Alaska Spent the morning in the lab. Checked stomachs of red-backs that Pitelka removed from his plot. 2 ♀♀ has lemming bones and tooth, little else. ♂ has fresh tipula larvae, no lemming material. Once again- if holds. Went out to Drum Area briefly. Decided to use lemming traplines as habitat-snow cover transects. Right after lunch started out and did: IVA-B, III A-B, I + II, IV + VI, VII + VIII, IX + X. This gave 6 x 102 points. I thought of making polygons by joining the ends of each pair of lines, but rejected this because of the inconsistent distances between lines. Managed to do them all in 1 afternoon- partially due to the fact that 5 lines (IVA-B, VIII, VII, and X) are completely snow covered. Found that 90.2% of the total was under snow, which matches my subjective evaluation. This left only 60 stations exposed-not really enough for a good habitat sample,
