It was very dark when we reached Fairhaven Cliff and Bolles began hooting like a Barred Owl. I followed with a feeble imitation of the Great-horned Owl which, after a few minutes and to my infinite surprise, was answered by Bubo himself from the tall pines on the west bank of the river. We stopped paddling, of course, and I continued the conversation in the best Owl language that I could command. Bubo was prompt in his responses and presently appeared directly over our heads—a great shadowy bird with broad wings and big head, flapping at first, then sailing as majestically as an Eagle, finally descending in a series of undulations to the low trees on the shore of the Cliff landing. More Owl talk and Bubo soon on his way back to the pines, evidently sorely puzzled and speedily impelled to repeat the flight which he made three times each way, in all, passing over us each time (page 23).

At 2 p.m. we started through the woods for Walden [Pond]. It was a walk to be long remembered. I think I have never before seen oak woods so richly colored as these—painted woods—wine-red the dominant tint. The scarlet oaks were steeped with this color and the undergrowth of huckleberry bushes seemed to reflect it, as the scarlet of the maples along the river was reflected by the water a week or more ago. Of course these huckleberry bushes were really of the same color as the oaks. In places they formed a rich unbroken carpet which covered the ground as far as the eye could reach under the trees. . .

The results of a classic study of the sea breeze, undertaken by the New England Meteorological Society during the summer of 1887 with a network of 130 observers in southeastern New Hampshire and eastern Massachusetts, including two observers (F. M. Holland and N. M. Bush) in Concord, one (Charles W. Jenks) in Bedford, one (Greenwood K. Oliver) at Kendal Green, one (M. Herbert Saunderson) in Waltham, and one (B. F. Howe) in Sudbury. In their concluding remarks (page 257), the authors state that the sea breeze “reaches the shore commonly between eight and eleven o’clock in the forenoon with a velocity of ten or fifteen miles an hour; its velocity rapidly diminishes inland. Its inland advance from the shore-line is made at first at a rate of from three to eight miles and hour, but slower afterwards when approaching its greatest penetration of ten or twenty miles in the late afternoon.” On June 7, “the sea-breeze travelled inland beyond Boston; Waltham was on the dividing line and experienced a calm during the whole afternoon, and west of that station a uniformly southwesterly wind prevailed, both winds being weak. In the same way the records of June 17th show the breeze to have advanced to Waltham, but beyond here the westerly winds were prevalent” (page 242). The sea breeze did not often reach inland as far as Walden Woods.

Endnote 29: The pickerel of Walden, now [1917] nearly, if not quite extinct, who lived in that pure water supplied by springs at the bottom, were quite different from those of the sluggish and more weedy river, with its darker water. The latter seemed of less delicate lines, and were of a dark, more muddy green, while the Walden pickerel were more silvery, and the green, as I recall it, was very pure, light and iridescent.

Hanley quotes the geologist, Joseph Hartshorn, as saying, “Walden Pond could have been a high hill, covered with an earth crust and supporting growing trees. And it could have collapsed into a pond, because the heart of the hill would have been a huge ice pocket left by the glacier. When the ice melted, the thin earth crust would have sunk to become the bottom of Walden Pond.”
