Journal Aug 21, 1962, Pt. Barrow, The winter, about a dozen will be sacrificed upon Dave's return for blood. Aug 22, 1962, Pt. Barrow, Alaska; Started on colony the first thing setting up the different -phases as completely as possible. New breeders were put together; a certain number were put on date, while other are receiving food and water ad libitum. The ones on date (12) will be used for blood and maybe the stomach contents if fed a certain grass. One Microtus sp. was dead in cage but others are doing well. We recorded the first good snowfall; none of it stuck, but the temp. never went above 40°. The evening, comparatively, seemed very mild but was still below 40°. Perhaps I missed it earlier but it was dark last night starting about 2300. I don't know when the sunrise came. Aug 23, 1962, Pt. Barrow, Alaska; Started on colony early morning. Finished most of it by noon. Routine work plus cleaning out some breeding cages. Temp climbed above 40° for most day. A couple of times, there was drizzles and dark clouds are present, but nothing. Aug 24, 1962, Pt. Barrow, Alaska; Finished routine work in colony early and started straightening things around the lab. Went to the Point, or rather toward the Point. I was with Holmes and Dee Shuley, a grad student from USC working for Dr. Moore.
