. Bird-lore . culty belongs also to several other diving-birds. Trusting extensivelv in its powers of swimming over and under water toescape its enemies, and to procure its food, it nevertheless is a strong flier, although progressing with apparently labored movements, andFlight in calm weather finding great difficulty in rising from the water. It must rise against the wind, so that the pressure of the breezeagainst its narrow pinions may assist in raising its weight from the surface.Once on the wing it may perform long journeys, as it does on its migrations, which take it many miles overland to and from the lake where it makes itshome. On these flights it sometimes sends forth a defiant note, attractingattention to its speeding form far above tree-tops and hills. In flying over theocean, it seems to feel that its true safety is in the water, for a sudden shout orstartling sound will often cause it to drop near the surface. This habit is oftentaken advantage of by gunners, as the bird flies overhead..

Here it finds an abundance of food, and, withhosts of other sea-fowls, rides out the winters fury. With the return of spring, and the warming of its stout heart toward itsmate, it again seeks the lake, and resumes its family cares. Year after year itreturns for a nesting-place to the same tiny islet, floating tussock (or it may beto a muskrat-house), to some sandy beach in a sheltered cove, or perhaps to apoint of land where turf and water meet. Sometimes the nest is fully open toview, sometimes well hidden by bushes, sometimes a mere hollow withoutlining, but it may be slightly or, occasionally, well
