that the north-eaft is, next to this, the principal wind towards the fea-coaft, and the north-weft is the predominent wind at the mountains. The diiFerence between thefe two winds to fenfation, and in faft, is very great. The north-eaft is loaded with vapour, infomuch, that the fait- makers have found that their cryftals would not fhoot while that blows; it brings a diftreffing chill, and is heavy and oppref- five to the fpirits: the north-weft is dry, cooling, elaftic and animating. The eaft- ern and fouth-eaftern breezes come on generally in the afternoon. They have advanced into the country very fenfibly within the memory of people now living. They formerly did not penetrate far above Williamfburgh. They are now frequent at Richmond, and every now and then reach the mountains. They depofit moft of their moifture hov/ever before they get that far. As the lands become more cleared, it is probable they will extend ftill further weftward.
Going out into the open air, in the temperate, and warm months of the year.
we often meet with bodies of warm air, which paffing by us .in two or three fe- conds, do not afford time to the moft fen- fible thermometor to feize their tempera- ture. Judging from my feelings only, I think they approach the ordinary heat of the human body. Some of them perhaps go a Uttle beyond it. They are of about 20 or 30 feet diameter horizontally. Of their heighth we have no experience, but probably they are globular volunins wafted or rolled along with the wind. But whence taken, where found, or how generated? They are not to be afcribed to volcanos, becaufe we have none. They do not hap- pen in the winter when the farmers kindle large fires in clearing up their grounds. They are not confined to the fpringfeafon, when we have fires which traverfe whole counties, confuming the leaves which have fallen from the trees.
