I. Cade 1958 Xema sabini 18 June - east of Barrac - On the flight with Mahw and 5 thanks, many julet were flying around and over the larger lakes and off shore around the Plover Islands. Over 100 were seen. Common in this area also last year. 26 June Coal Mine, Maple River - On an island in a lake ca 1 mi's or 5/10 of camp I spotted a pair of these gulls. One was active and kept chasing after flocks of red phalaropes in the area and occasionally, also, after terns. The other kept sitting in the same spot. Oc- casionally the active one would land near by. Quest was indicated. On the S.E. side of the lake the water was shallace, so that by removing my boots I was able to wade out. The nest held 3 eggs. It was a depression in a mound of myon ca 7 ft square which was just barely above water level. A scattering of ridges was growing on the mound. Also a lot of dead, coarse grass had formed a shift lip on the side nearest the nest. The next scrape was lined with dead grass. The mound was completely surrounded by an inundated area of ridges at the center
