"In the fall," says Thoreau, "the Loon came, as usual, to moult and bathe in the pond, making the woods ring with his wild laughter before I had risen. At rumor of his arrival all the mill-dam sportsmen are on the alert, in gigs and on foot, two by two and three by three, with patent rifles and conical balls and spy glasses. They come rustling through the woods like autumn leaves, at least ten men to one loon. Some station themselves on this side of the pond, some on that for the poor bird cannot be omnipresent; if he dive here he must come up there. But now the kind October wind raises, rustling the surface of the water, so that no loon can be heard or seen. The waves generously rise and dash angrily, taking sides with all water-fowl, and our sportsman must beat a retreat to town and shop and unfinished jobs. But they were too often successful. As I was paddling along the north shore one very calm October afternoon, for such days especially they settle on the lakes, like the milkweed down, a Loon, suddenly sailing out from the shore toward the middle a few rods in front of me, set up his wild laugh and betrayed himself. I pursued with a paddle and he dived, but when he came up I was nearer than before. He dived again, but I miscalculated the direction he would take, and we were fifty rods apart when he came to surface this time, for I had helped to widen the interval; and again he laughed long and loud, and with more reason than before. He maneuvered so cunningly that I could not get within half a dozen rods of him. Each time, when he came to the surface, turning his head this way and that, he coolly surveyed the water and the land, and apparently chose his course so that he might come up where there was the widest expanse of water and at the greatest distance from the boat. It was surprising how quickly he made up his mind and put his resolve into execution. He led me at once to the widest part of the pond, and could not be driven from it. While he was thinking one thing, I was endeavoring to divine his thought. It was a pretty game, played on the smooth surface of the pond, man against a Loon. Some times he would come up unexpectedly on the other side of me, having apparently passed directly under the boat. So long-winded was he and so unweariable, that when he had swum farthest he would immediately plunge again, nevertheless; and then no wit could divine where in the deep pond he might be speeding his way like a fish, for he had time and ability to visit the bottom of the pond in its deepest part. It is said Loons have been caught in the New York lakes eighty feet beneath the surface, with hooks set for trout. I found that it was as well for me to rest on my oars and wait his reappearing; for again and again, when I was straining my eyes over the surface one way, I would be startled by his unearthly laugh behind me. He was indeed a silly Loon, I thought, for why, after displaying so
