cease, for the more cessation the less killing in the long run—the end should sanctify the means.
May 8th.—At 1.40 p.m. find both birds off the nest, and I can see, through the glasses, at least two of the white eggs quite distinctly. There was no question of the birds having been alarmed by me, for I was much beyond the limit at which I have ever alarmed them before. It would seem therefore as if the birds did not cover their eggs in leaving when not disturbed. In a minute or two the male makes his leap on to the nest, and sits on the eggs. In coming up to the tree from which I watch, I do not this time disturb him. As usual, I soon lose sight of the female, who has swum right away.
1.40.—The female returns to the nest, swimming quietly up to it. I do not see her till she is there. The male then stands up, gives himself a preen or two with the beak, and takes the water, when the hen with hardly a pause jumps up. She stands a little, and moves the weeds about with her beak before settling down. The male, on leaving, goes to the bank, and (I think without diving) brings from it to the nest a small piece of weed. He then swims twice a little distance out, dives, and, coming up each time with a good beakful, brings them both to the nest, and the female afterwards arranges them upon it with her beak. Thus day by day, while the birds are sitting, the bulk of the nest is added to, and always, so far as I have yet seen, by the male bird.
2.—The male bird has also now gone a good way off, but I still see him on the water.
2.25.—The male back at the nest, and there is now more arranging of the weeds by the two birds together. After this the male swims off again, there being no change on the nest.
2.55.—The female leaves the nest, in alarm, I think, at an approaching boy in charge of a flock of Sheep.
May 17th.—Upon coming here to watch again I find the nest plundered and destroyed.
May 19 th.—Coming again this morning, about 6.30 a.m., I see one bird swimming by itself in the neighbourhood of the destroyed nest, and farther off a pair of them.
After some time the single male bird swims to and meets the female of the other two, she having swum to him, leaving her
