Journal July 3, (cont') Dane Mullen came in and wanted to take blood samples of healthy lab lemmings of the approximate weight to some stressed animals (lemmings) which had had their blood sampled. After the sampling I helped Mullen process the blood. I worked some more on the colony until dinner and finished the colony after dinner. The weather Today was varied with snow flurries and sunshine. Tonight a fog is settling in but visibility is good for about a half-mile. July 4, 1962, Pt. Barrow; Clear, cool day (40's), slightly overcast but clearing by cate afternoon. I worked on the colony today mostly having a great deal more to do than usual. Holmes & Sullivan checked the traplines EXT. EXT. this morning without finding any catches. In the colony I am fairly sure one female is pregnant due to a vaginal plug and another fairly certain due to a large increase in weight. Mullen is having breeding cages built with movable hinged doors for observation. There are no extra lemmings not in individual cages. After dinner Holmes & I went out, he went on to check the traplines EXT. EXT. and I stopped in the central Marsh to hunt specimens. Holmes returned about an hour later after I had got [illegible] only a Pectoral Sandpiper. Together we cut across central marsh stopping in the middle to shoot a Phalarope and a Red-Back Sandpiper.
