P. M. - To Fair Haven Hill. Miss Caroline Pratt saw the white bobolink yesterday where Channing saw it the day before, in the midst of a large flock. I go by the place this afternoon and see very large flocks of them, certainly several hundreds in all, and one has a little white on his back, but I do not see the white one. Almost every bush along this brook is now alive with these birds. You wonder where they were all hatched, for you may have failed to find a single nest. I know eight or ten active boys who have been searching for these nests the past season quite busily, and they have found but two at most. Surely but a small fraction of these birds will ever return from the South. Have they so many foes there? Hawks must fare well at present. They go off in a straggling flock, and it is a long time before the last loiterer has left the bushes near you.
