Henry and others speak of a rock of pure copper, from which the former out off 100 lbs. weight. W. Schoolcraft examined the remainder of the mass in 1820, and found it of irregular shape; in its greatest length three feet eight inches, greatest breadth three feet four inches, making about eleven cubic feet, and containing, of metallic matter, about 2200 lbs.; but there were many marks of chisels and axes upon it, as if a great deal had been carried off. The surface of the block, unlike most metals which have suffered a long exposure to the atmosphere, presents a metallic brilliancy.—Martin's History of Canada, p. 175.

Weld mentions having seen in the possession of a gentleman at Niagara a lump of copper, of several ounces weight, apparently as pure as if it had passed through the fire, which had been struck off with a chisel from a piece equally pure, growing on one of the islands in Lake Superior. Rich veins of copper are visible in almost all the rocks on these islands near the shore; and copper ore, resembling copperas, is likewise found in deep beds near the water.—Weld, p. 346.

In Charlevoix's time (1720), "on trouvoit sur les bords du Lac Supérieur et autour de certains isles, de grosses pièces de cuivre qui sont l'objet de cette superstition des sauvages; ils les regardent avec vénération comme un présent des Dieux qui habitent sous les eaux; ils en ramassent les plus petits fragmens et les conservent avec soin, mais ils n'en font aucune usage. J'ai connu un de nos frères lequel étoit orfévre de son métier, et qui, pendant qu'il étoit dans la mission du Sault Sainte Marie, en étoit allé chercher là, et en avoit fait des chandeliers, des croix, et des encensoirs, car ce cuivre est souvent presque tout pur."—Tom. v., p. 415.

Kalm says that the copper found is so pure that it does not require melting over again, but is fit for working immediately.—Kalm in Pinkerton, vol. xiii., p. 691 (1748).

"Before saying good-by to Lake Superior, let me add, that since the date of my visit, the barren rocks which we passed have become an object of intense interest, promising to rival, in point of mineral wealth, the Altai chain and the Uralian Mountains. Iron had long been known to abound on the northern shore, two mines having been at one time worked and abandoned, chiefly on account of temporary obstacles, which the gradual advance of agriculture and civilization was sure to remove; and, more recently, the southern shore, though of a much less favorable character in that respect, was found to possess rich veins of copper and silver. Under these circumstances, various enterprising persons in Canada have prosecuted investigations which appear to have satisfactorily proved that, in addition to their iron, the forbidding wastes of the northern shore contain inexhaustible treasures, both of the precious and of the useful metals, of gold and of silver, of copper and tin, and already have associations been formed to reap the teeming harvest."—Sir G. Simpson's Journey round the World, vol. i., p. 35 (1841).

The following extract is from a Quebec newspaper, bearing date 25th June, 1848:

"The Copper Region: Singular Discovery.—A correspondent of the Buffalo Express, writing under date June 14, from Ontonagon, Lake Superior, says:

"'Mr. Knapp, of the Vulcan Mining Company, has lately made some very singular discoveries here in working one of the veins which he lately found. He worked into an old cave which has been excavated centuries ago. This led them to look for other works of the same sort, and they have found a number of sinks in the earth which they have traced a long distance. By digging into those sinks they find them to have been made by the hand of man. It appears that the ancient miners went on a different principle from what they do at the present time. The greatest depth yet found in these holes is thirty feet: after getting down to a certain depth, they drifted along the vein, making an open cut. These cuts have been filled nearly to a level by the accumulation of soil; and we find trees of the largest growth standing in this gutter, and also find that trees of a very large growth have grown up and died, and decayed many years since; in the same places there are now standing trees of over three hundred years' growth. Last week they dug down into a new place, and about twelve feet below the surface found a mass of copper that will weigh from eight to ten tons. This mass was buried in ashes, and it appears they could not handle it, and had no means of cutting it, and probably built fire to melt or separate the rock from it, which might be done by heating, and then dashing on cold water. This piece of copper is as pure and clean as a new cent; the upper surface has been pounded clear and smooth. It appears that this mass of copper was taken from the bottom of a shaft, at the depth of about thirty feet. In sinking this shaft from where the mass now lies, they followed the course of the vein, which pitches considerably: this enabled them to raise it as far as the hole came up with a slant. At the bottom of a shaft they found skids of black oak, from eight to twelve inches in diameter: these sticks were charred through, as if burned: they found large wooden wedges in the same situation. In this shaft they found a miner's gad and a narrow chisel made of copper. I do not know whether these copper tools are tempered or not, but their make displays good workmanship. They have taken out more than a ton of cobble-stones, which have been used as mallets. These stones were nearly round, with a score cut around the tenter, and look as if this score was cut for the purpose of putting a withe round for a handle. The Chippewa Indians all say that this work was never done by Indians. This discovery will lead to a new method of finding veins in this country, and may be of great benefit to some. I suppose they will keep finding new wonders for some time yet, as it is but a short time since they first found the old mine. There is copper here in abundance, and I think people will begin to dig it in a few years. Mr. Knapp has found considerable silver during the past winter.'"

Acosta is the first philosopher who endeavored to account for the different degrees of heat in the Old and New Continents by the agency of the winds which blow in each, (Hist. Moral., lib. ii. and iii.) M. de Buffon adopted the same theory, and illustrated it with many new observations. "The prevailing winds, both in Upper and Lower Canada, are the northeast, northwest, and southwest, which all have a considerable influence on the temperature of the atmosphere and the state of the weather. The southwest wind is the most prevalent, but it is generally moderate, and accompanied by clear skies; and the northeast and easterly winds usually bring with them continued rain in summer, and snow in winter; the northwest is remarkable for its dryness and elasticity, and, from its gathering an intense degree of frigor as it sweeps over the frozen plains and ice-bound hills in that quarter of the continent, invariably brings with it a perceptible degree of cold. Winds from due north, south, or west are not frequent. At Quebec, the direction of the wind often changes with the tide, which is felt for nearly sixty miles higher up the stream of the St. Lawrence."—Bonchette, vol. i., p. 343.

"The northwest wind is uncommonly dry, and brings with it fresh animation and vigor to every living thing. Although this wind is so very piercing in winter, yet the people never complain so much of cold as when the northeast wind blows. The northeast wind is also cold, but it renders the air raw and damp. That from the southeast is damp, but warm. Rain or snow usually falls when the wind comes from any point toward the east. The northwest wind, from coming over such an immense tract of land, must necessarily be dry; and, coming from regions eternally covered
