and rolling them down the bank. Here she got an angle-worm about w which she was not at all finicky, and bolted it down at once. Evidently these worms are not so bad when one is hungry. She also gobbled a little snail about a quarter of an inch in diameter without breaking its shell. She is unusually abounding in vitality this morning, full of confidence, even talking a little and answering from the bushes. I did not see the change of shift, as I had to go down town. At 10:40 Brown-eyes was on the nest and G.E. very friendly and eager for food. I gave him more worms than he deserved, as I wished to see if he would take one up to his mate as he has done on previous oc- casions, and then change shifts; but he gulped them all himself, finally going away satisfied. I had thought that this was about the right time to change shift, but it seemed not. At 11:20. Went out again and G.E. was just settling himself on the nest. It was about the right time to change. Browneyes was nervous about something and would only dart for worms, snatch them and re- tire into the bushes and dig. 2:40. Green-eyes on duty. Probably there has been a shift in the meantime. B.E. calling: "Scrip, scrip" outside the fence. Mr. Sampson present. B.E. comes through the fence for worms, her ner nervousness of a short time ago having disappeared. She starts for the nest with a worm. S goes up to it to observe the shift. G.E. opens his bill and B.E. hands him the worm, whereupon G.E. promptly departs and B.E. settles on the eggs, of which there are still but 3. This is a standard shift. It looks as if the set is complete. Incubation commenced immediately with the first egg and has proceed- ed continuously ever since; interruptions, as previously noted, being usually only a matter of seconds at each change.
