The sensations of my climb into this fish-hawk's nest of the marsh are vivid even now. Going up was comparatively easy. When I reached the forks holding the nest, I found I was under a bulk of sticks and corn-stalks which was about the size of an ordinary haycock or an unusually large wash-tub. By pulling out, pushing aside, and breaking off the sticks, I worked a precarious way through the four feet or more of debris and scrambled over the edge. There were two eggs. Taking them in my hands, so as not to crush them, I rose carefully to my feet. Upright in a hawk's nest! Sixty feet in the air, on the top of a gaunt old white oak, high above the highest leaf, with the screaming hawks about my head, with marsh and river and bay lying far around! It was a moment of exultation; and the thrill of it has been transmitted through the years. My body has been drawn to higher places since; but my soul has never quite touched that altitude again, for I was a boy then. Nor has it ever shot swifter, deeper into the abyss of mortal terror than followed with my turning to descend. I looked down into empty air. Feet foremost I backed over the rim, clutching the loose sticks and feeling for a foothold. They snapped with the least pressure; slipped and fell if I pushed them, or stuck out into my clothing. Suddenly the sticks in my hands pulled out, my feet broke through under me, and for an instant I hung at the side of the nest in the air, impaled on a stub that caught my blouse as I slipped. There is a special Providence busy with the boy. This huge nest of the fish-hawks was more than a nest; it was a castle in very truth, in the sheltering crevices of whose uneven walls a small community of purple grackles lived. Wedged in among the protruding sticks was nest above nest, plastering the great pile over, making it almost grassy with their loose flying ends. I remember that I counted more than twenty of these crow-blacks' nests the time I climbed the tree, and that I destroyed several in breaking my way up the face of the structure. Do the blackbirds nest here for the protection afforded by the presence of the hawks? Do they come for the crumbs which fall from these great people's table? Or is it the excellent opportunity for social life offered by this convenient apartment-house that attracts? The purple grackles are a garrulous, gossipy set, as every one knows. They are able-bodied, not particularly fond of fish, and inclined to seek the neighborhood of man, rather than to come out here away from him. They make very good American rooks. So I am led to think it is their love of "neighboring" that brings them about the hawk's nest. If this surmise is correct, then the presence of two families of English sparrows among them might account for there being only eight nests now, where a decade ago there were twenty.
