Mr. Brewster, in describing his experience with this species in the Gulf of St. Lawrence, writes: “The first report of our guns brought dozens tumbling from their nests. Their manner of descending from the higher portions of the clifi was peculiar. Launching into the air with beads depressed and wings held stiflly at a sharp angle above their backs, they would shoot down like meteors, checking their speed by an upward turn just before reaching the water. In a few minutes scores had collected about us. They were perfectly silent and very tame, passing and repassing over and by us, often coming within ten or fif- teen yards. On such occasions their flight has a curious resemblance to that of a Woodcock, but when coming in from the fishing grounds they skim close to the waves, and the wings are moved more in the manner of a Duck ” (Proc.

When they finally concluded I was an unsafe neighbor, they lost no time in getting out of sight, diving with surprising suddenness. They usually swam a
