Of one the skin was subsequently lost, leaving the specimen represented by a skull only. The muskrats fre- quented a series of little ponds just above the reach of the tides, where the grasses of the salt marsh gave place to clusters of reeds and thickets of alder and willow. These ponds were connected by well trodden trails through the grass, like large Microtus runways, paths that could be. Fig. W. Marsh at western end of Sergief Island, Alaska. The roeky back- bone of the island, densely covered with spruce, rises abruptly from the sur- rounding swamps. At the base of this slope is a bordering fringe of bushes, mostly alder, red-berry elder and willow, with, underneath, tangles of salmon- berry and devil's club. The marshes farthest inland, as here shown, are mostly of fresh water, with growths of tules and other fresh-water plants. This pond and others nearby were frequented by muskrats. The surface of this pond was in part covered with floating tules that had been recently cut by these mam- mals. Birds seen in such surroundings were green-winged teal, pintail, mallard, pectoral sandpiper, and Wilson snipe. Black swifts were seen almost daily soaring over this marsh.

All along these trails there were signs of muskrat activities, masses of cut reeds floating in the ponds, and piles of coarse grass and other vegetation in the drier places. There were.
