These nuts are round, and after a little exposure become black, except in that part which originally formed the point of attachment to the receptacle, which is an oblong spot three-fourths of an inch in diameter; the whole bearing some resemblance to the eyeball of a deer, or other animal. Hence the name _buck-eye_, which is applied to the tree. The several species of æsculus are confined principally to the western states and territories. In allusion to this circumstance, the indigenous backwoodsman is sometimes called buck-eye, in distinction from the numerous emigrants who are introducing themselves from the eastern states. The opprobrious name of Yankee is applied to these last, who do not always stand high in the estimation of the natives of the south and west. Few of these sectional prejudices are, however, to be discovered in Ohio, the greater part of the population here having been derived from New England. Cincinnati, which in 1810, contained 2500 inhabitants, is now said to number about 12,000.[025] Its plan is regular, and most of the buildings are of {21} brick. The dwellings are neat and capacious, and sometimes elegant. The site of the town was heretofore an aboriginal station, as appears from the numerous remains of ancient works still visible. We forbear to give any account of these interesting monuments, as they have already been repeatedly described.[026] On Tuesday, the 18th, the weather becoming clear and pleasant, Dr. Baldwin thought himself sufficiently recovered to proceed on the voyage; accordingly, having assisted him on board the boat, we left Cincinnati at ten o'clock. During our stay at that place, we had been gratified by the hospitable attentions of the inhabitants of the town. Mr. Glen was unremitting in his exertions to promote the recovery of Dr. Baldwin's health; to him, as well as to Dr. Drake, and several other gentlemen of Cincinnati, all the members of our party were indebted for many friendly attentions. Below Cincinnati the scenery of the Ohio becomes more monotonous than above. The hills recede from the river, and are less elevated. Heavy forests cover the banks on either side, and intercept the view from all distant objects. This is, however, somewhat compensated by the magnificence of the forests themselves. Here the majestic platanus attains its greatest dimensions, and the snowy whiteness of its branches is advantageously contrasted with the deep verdure of the cotton-wood, and other trees which occur in the low grounds.
