16. Journal 28 June Barrow, Alaska Today is overcast with the cold wind still blowing from the east. Some mist started in the evening from a heavy fog which cut visibility to 500 yds. I worked in the lemming colony until noon weighing the animals, adding queso to the pregnant ones and mothers, charging the ones in the metabolic cages. Steve Holland suggested a practical change in the wire gauge of the metabolic cages. By his method, the feces may be completely eliminated from mixing with the urine. All metabolic animals survived but are losing weight (small.) The animal eating the Schultz diet without the binding agent is doing fair. Difficult to tell whether any significant changes are evident. After lunch > talked with Dave Mullen about some problems in the colony, Hank Childs, Pitelka and I set lines III A,B & IV A,B. A Red-backed vole with 4 eggs was found and staked near 0.0 on III A. A pectoral vole between III A,B but wasn't located. A Golden Plover nest is on III B. IV A,B are as well drained as they ever will be. Returned about 17:43. Hank is not feeling well because of his leg... Mrs. Won. Steve came today.. 29 June Barrow, Alaska Checked traplines III A,B & IV A,B. Only one lemming was taken. Clear day with wind from east but not as cold as yesterday. Returned to help Steve Holland with the rest of the colony work. Efficient methods
