Urinator imber. Lake Umbagog, Maine. 1898. I awoke at daybreak this morning and the first sound Aug.24. that I heard was a rapid whuff-whuff-whuff closely resembling the puffing of a steam engine and passing directly over the tent. I knew at once that it was made by the wings of some large bird and a moment later the prolonged, quavering laugh of a Loon proclaimed the particular species. Loons often fly over PinePoint in the early morning but seldom or never by day.
