Journal 26 June mothers. After coffee, Hank Childs, Dave Mullen and went to the area around the Duck Camp to collect lemmings for the colony. We collected nine and returned at lunchtime. Dr. Schultz left for Berkeley today. I set up data sheets on the nine new animals and then worked on the metabolic cages. A very mild day with a wind from the east until 1300. At this time clouds rolled in along with the constant wind. By 1700 a fog lay over the coast hiding [illegible]. I checked traps at 1800 yielding a 8 Dicrostomus and a 8 Longspur. Wrote notes. 27 June Barrow, Alaska. Checked lines IV+VI. Found one 8 Lemmus and one 3 Longspur. Found nothing in the line traps. While checking the line traps, a 9 adult (pregnant) was caught. Returned and wrote the catches in the trapbook. Started the rest on data and helped Steve Holland on the routine work until noon. After lunch we worked on the metabolic cages and then put six predetermined animals into the cages. These are to be given lab chow for 4 days until a diet of a single species of grass will start. A powder from the Schultz special diet without the binding agent was given with a 8 Adult to see if it will be eaten. A 9 with a letter Z 8 failed all but one and ignored this one so that it was dying. After the movie, about 2100, Hank and I picked up lines IV+VI. No catch was made. Very windy & cold with some fog all day.
