Mustela Jun. 20. Barrow Alaska. At least one of this species was observed in this part of Britton's Area S of South Salt Lagoon. This animal was noticed poking its head above the snow, as Paul trod a lemming and the lemming screamed. The weasel would raise its head like a periscope for several seconds then lower it. The head would appear later perhaps in the same place, perhaps in another. The weasel approached to within about 15 ft. It travelled on top of the snow at some times and under it at others. After it approached to within 15 ft., it turned around and returned to where it was seen about 40 ft. away. It or another weasel then came back to the same place 15 ft. away. This time the weasel carried a dead lemming. It was carried in the mouth and probably weighed more than the weasel. The place where the weasel disappeared, 15 ft. away, was then examined. It appeared to be some sort of feeding area. The ground was covered with fur. Trails which looked to have been made by the weasel radiated in all directions in the snow.
