Mr. Chamberlin told me that there was no corporation in Worcester except the banks (which I suspect may not be literally true), and hence their freedom and independence. I think it likely there is a gas company to light the streets at least. John Mactaggart finds the ice thickest not in the largest lakes in Canada, nor in the smallest, where the surrounding forests melt it. He says that the surveyor of the boundary-line between England and United States on the Columbia River saw pine trees which would require sixteen feet in the blade to a cross-cut saw to do anything with them. I examined to-day a large swamp white oak in Hubbard’s meadow, which was blown down by the same storm which destroyed the lighthouse. At five feet from the ground it was nine and three fourths feet in circumference; the first branch at eleven and a half feet from ground; and it held its size up to twenty-three feet from the ground. Its whole height, measured on the ground, was eighty feet, and its breadth about sixty-six feet. The roots on one side were turned up with the soil on them, making an object very conspicuous a great distance off, the highest root being eighteen feet from the ground and fourteen feet above centre of trunk. The roots, which were small and thickly interlaced, were from three to nine inches beneath the surface (in other trees I saw them level with the surface) and thence extended fifteen to eighteen inches in depth (_i. e._ to this depth they occupied the ground). They were broken off at about eleven feet from the centre of the trunk and were there on an average one inch in diameter, the largest being three inches in diameter. The longest root was broken off at twenty feet from the centre, and was there three quarters of an inch in diameter. The tree was rotten within. The lower side of the soil (what was originally the lower), which clothed the roots for nine feet from the centre of the tree, was white and clayey to appearance, and a sparrow was sitting on three eggs within the mass. Directly under where the massive trunk had stood, and within a foot of the surface, you could apparently strike in a spade and meet with no obstruction to a free cultivation. There was no taproot to be seen. The roots were encircled with dark, nubby rings. The tree, which still had a portion of its roots in the ground and held to them by a sliver on the leeward side, was alive and had leaved out, though on many branches the leaves were shrivelled again. _Quercus bicolor_ of Bigelow, _Q. Prinus discolor_ Mx. f. [Illustration] I observed the grass waving to-day for the first time,—the swift Camilla on it. It might have been noticed before. You might have seen it now for a week past on grain-fields. Clover has blossomed.
