Childs 1955 Lemmings July 16 Wainwright, Alaska Caref where there were runways + in areas where runways had not developed as yet. The top of the polygons have been mowed clean and all tussocks are shaggy several inches of new growth with no last years growth remaining. Hahn told me that all last winter there was grass showing thru the snow in this area and that the snow was not more than 3" on the top of the polygons. Prevailing wind is from the East. There may be as much as 5" grass growth on the Caref in the troughs between the polygons where the lemmings are now found. July 18 Caught a ♀ in runway. It did not run last freeze and I only just happened to look down at it. Maybe we miss more of them, because of this behavior. July 19 Caught a ♀ in T3 by hind foot. She gave birth to 6 young after dragging the trap some distance. The future of any T4 is not producing when it is essentially in the same habitat at T3 is not clear. There is more recently filled in low polygon centers with sparse vegeta- than in T3. July 22 Have not seen the extensive scatoria in runways as I noted at the Meade. In trapping south of the village in the marsh I got several double catches of adult lemmings in
