Geographical Description of Louisiana. Its Climate
Louisiana that part of North America, which is bounded on the south by the Gulf of Mexico; on the east by Carolina, an English colony, and by a part of Canada; on the west by New Mexico; and on the north, in part by Canada; in part it extends, without any assignable bounds, to the Terrae Incognitae, adjoining to Hudson's Bay.[35] Its breadth is about two hundred leagues,[36] extending between the Spanish and English settlements; its length undetermined, as being altogether unknown. However, the source of the Missisippi will afford us some light on this head.
The climate of Louisiana varies in proportion as it extends northward: all that can be said of it in general is, that its southern parts are not so scorching as those of Africa in the same latitude; and that the northern parts are colder than the corresponding parts of Europe. New Orleans, which lies in lat. 30°, as do the more northerly coasts of Barbary and Egypt, enjoys the same temperature of climate as Languedoc. Two degrees higher-up, at the Natchez, where I resided for eight years, the climate is far more mild than at New Orleans, the country lying higher: and at the Illinois, which is between 45° and 46°, the summer is in no respect hotter than at Rochelle; but we find the frosts harder, and a more plentiful fall of snow. This difference of climate from that of Africa and Europe, I ascribe to two causes: the first is, the number of woods, which, though scattered up and down, cover the face of this country: the second, the great number of rivers. The former prevent the sun from warming the earth; and the latter diffuse a great degree of humidity: not to mention the continuity of this country with those to the northward; from which it follows, that the winds blowing from that quarter are much colder than if they traversed the sea in their course. For it is well known that the air is never so hot, and never so cold at sea, as on land.
We ought not therefore to be surprised, if in the southern part of Louisiana, a north wind obliges people in summer to be warmer cloathed; or if in winter a south wind admits of a lighter dress; as naturally owing, at the one time to the dryness of the wind, at the other, to the proximity of the Equator.
Few days pass in Louisiana without seeing the sun. The rain pours down there in sudden heavy showers, which do not last long, but disappear in half an hour, perhaps. The dews are very plentiful, advantageously supplying the place of rain.
