T. Code 1937 Lemnaceae trinervisovatus 10 June - Wainwright, Alaska Soon after we got into the village, none of the kids brought in 3 cans full of live lemmings. They bought 21 of them for the lab at 50¢ each. The rest were in too poor a condition to keep. Earlier Mr. Cowanfield had sent back to Barrow a second batch of 200 dead ones. 11 June - Set out the transects this morning and looked over the general area. Saw half a dozen animals running through tunnel or along some crops. All the high geared - high centric polygons with terraces - is entirely covered by new crop and freshly dug tunnels in the dirt. There is a good deal of willow matting in their vegetation, and the new crop and tunnels are frequently cut through around patches of willow brush. The vegetation - grass and rushes - in the troughs of the polygons is measured down just as at Barrow; after a high, the vegetation or higher grazing - Eriophorum turfs, even willow, shi-ches etc. - is closely cropped in many places, but good regeneration seems to be starting. These animals give the impression that they comprise a comfortable population that will be able to continue increasing through their summer and reach a peak next
