Journal June 18, 1962, Pt. Barrow, Alaska. Day was overcast with intermittent showers. The tundra was covered by a light haze by the afternoon. Went with the Dove Mullen just south of ARL to collect lemming blood samples. We sampled eleven animals, all caught in the line of barrels nearest to the fresh water lake on the west tside. Finished my work in the animal (lemming) colony just after lunch and helped Mullen process the blood samples for the rest of the afternoon. That evening, I went through a square "cake" set for insects (Hymen). There was some bird activity in the field today even though we were only a small distance out. The water is running off rapidly now. June 19, 1962, Pt. Barrow, Alaska; Strong wind blowing in from NWN. Clear day, temp. about 50°F. Started on lemming colony. Stopped to observe Mullen do an autopsy on some lemmings used for blood samples. Mullen very adept. Continued working on colony until 12:30. Read some yesterday. Rechecked lemming colony twice. June 20, 1962, Pt. Barrow, Alaska; Still windy, morning temp. was high for this, but in afternoon, temp. dropped more. Worked on colony until 13:00. Prepared some extra cages to dispose the numbers of lemmings in the dry cage. Set traps with Sullivan on line 9410 about 14:00. The lines have some water at different points. Doubt if there is much activity in the area for lemmings, were because a jaeger (predator) and a snowy owl [illegible] right beside the lines. Bitelka didn't fly to Umiat
