The specimen of Uria troile drawn with a white line round the eye was a female; the one without this line was a young bird. I have drawn seventeen and a half hours this day, and my poor head aches badly enough. One of Captain Billings' mates told me of the Procellarias breeding in great numbers in and about Mount Desert Island rocks, in the months of June and July; there they deposit their one white egg in the deepest fissures of the rocks, and sit upon it only during the night. When approached whilst on the egg, they open their wings and bill, and offer to defend themselves from the approach of intruders.
