fasting, in the morning, a glass of brandy, in which was infused a teaspoonfull of Peruvian bark. This mixture is deemed, in the country, one of the most certain preventatives against the disorder, and few that take it, in time, regularly, and avoid the evening dews, suffer from it. Not only the town of Niagara and its vicinity are unhealthy places, but almost every part of Upper Canada, and of the territory of the States bordering upon the lakes, is likewise unhealthy. The sickly season commences about the middle of July, and terminates about the first week of September, as soon as the nights become cold. Intermittent fevers are the most common disorders; but in some parts of the country the inhabitants suffer from continual fevers, of which there are different kinds, peculiar to certain districts. In the country, for instance, bordering upon the Genesee River, which falls into Lake Ontario on the southern side, a fever is common amongst the inhabitants of a malignant nature, vulgarly called the Genesee fever, of which many die annually: and in that bordering upon the Miami River, which falls into Lake Erie, within the north-western territory of the United States, a fever of a different kind, again, is common. It does not appear that the exact nature of these different fevers has ever been accurately ascertained. In the back parts of North America, in general, medical men are rarely to be met with, and indeed if they were, the settlements are so far removed from each other, that they could be of little service. [Sidenote: EMIGRATIONS.] It is very remarkable, that notwithstanding that medical assistance is so rarely to be had in case of sickness in the back country, yet the Americans, when they are about to change their place of abode, seldom or ever consider whether the part of the country to which they are going is healthy or otherwise, at least they are scarcely ever influenced in their choice of a place of residence either by its healthiness or unhealthiness. If the lands in one part of the country are superior to those in another in fertility; if they are in the neighbourhood of a navigable river, or situated conveniently to a good market; if they are cheap, and rising in value, thither the American will gladly emigrate, let the climate be ever so unfriendly to the human system. Not a year passes over, but what numbers of people leave the beautiful and healthy banks of the Susquehannah River for the Genesee country, where nine out of every ten of the inhabitants are regularly seized, during the autumn, with malignant fevers; but the lands bordering upon the Susquehannah are in general poor, whereas those in the Genesee country are in many places so rich, that until reduced by successive crops of Indian corn, wheat, to use the common phrase, “will run wholly to straw:” where it has been sown in the first instance, the stalks have frequently been found fourteen or fifteen feet in length, two thirds of them lying on the ground.
