They must have been particularly sooty this morning. One plunge apiece, so far from sufficing, seemed hardly a beginning. They kept diving in over and over, continuing so long that finally I grew curious to know how many dips they were taking, and so, in order to count his dives, I singled one out, after most of the flock had done and gone off to hawk. How many he had taken before I marked him, and how many more he took after I lost him among the other birds, I cannot say; but, standing up in the skiff, I followed him around and around until he made his nineteenth splash,--in less than half as many minutes,--when I got so groggy that his twentieth splash I came near taking with him. The pond narrows toward the head, and just before it becomes a creek again the channel turns abruptly through the docks in against the right shore, where the current curls and dimples darkly under the drooping branches of great red maple; then it horseshoes into the middle, coming down through small bush-islands and tangled brush which deepen into an extensive swamp. June seemed a little tardy here, but the elder, the rose, and the panicled cornel were almost ready, the button-bushes were showing ivory, while the arrow-wood, fully open, was glistening snowily everywhere, its tiny flower crowns falling and floating in patches down-stream, its over-sweet breath hanging heavy in the morning mist. My nose was in the air all the way for magnolias and water-lilies, yet never a whiff from either shore, so particular, so unaccountably notional are some of the high-caste flowers with regard to their homes. The skiff edged slowly past the first of the islands, a mere hummock about a yard square, and was turning a sharp bend farther up, when I thought I had a glimpse of yellowish wings, a mere guess of a bird shadow, dropping among the dense maple saplings and elder of the islet. Had I seen or simply imagined something? If I had seen wings, then they were not those of the thrasher,--the first bird that came to mind,--for they slipped, sank, dropped through the bushes, with just a hint of dodging in their movement, not exactly as a thrasher would have moved. Drifting noiselessly back, I searched the tangle and must have been looking directly at the bird several seconds before cutting it out from the stalks and branches. It was a least bittern, a female. She was clinging to a perpendicular stem of elder, hand over hand, wren fashion, her long neck thrust straight into the air, absolutely stiff and statuesque.
