tice with nurserymen who raise this species from seed, the plants, by autumn,with careful treatment, will be 2 ft. or 3 ft. in height.

Statistics. Recorded Trees. On a little island in the Ohio, 15 miles above the mouth of theMuskingum, the eider Michaux measured a button-wood tree, which, at 5 ft. from the ground, was40 ft. 4s in in circumference. Twenty years before, General Washington had measured the same tree,and found it to be nearly the same size. In 1802, the younger Michaux found, on the right bank ofthe same river (the Ohio), about 36 miles from Manitta, a plane tree, the base of which was swollenin an extraordinary manner; and which, at 4 ft. from the ground, measured 47 ft. in circumference.This tree, which exhibited the most vigorous vegetation, began to ramify at 20 ft. from the ground; butMichaux saw several trees which had not a single branch till they had attained the height of 60 ft.or 70 ft. In the notes to Hunter’s Evelyn, an Occidental plane at Shadwell Lodge is recorded asremarkable for its speedy growth. When planted, in April, 1744, it was 8 ft. high ; and, when mea-sured in 1775, 31 years afterwards, it was 65ft. 9in. high, with a clear trunk of 20ft.; which,at 6 in. from the ground, measured 7 ft. 9 in. in circumference ; and at 20 ft., 4 ft. 6 in. At Biel, inEast Lothian, there was, in 1812, an Occidental plane near a fishpond, 45 ft. high, with a trunk 7 ft.

1 in. in circumference at 4 ft. from the ground. Another tree, near the same pond, measured 8 ft.5 in. in circumference. {Plant. Kal., p. 568.)
