greater velocity at that side than it does at the other, as the rapids above the precipice are strongest there. It is from the center of the Horse-shoe Fall that arises that prodigious cloud of mist which may be seen so far off. The extent of the Horse-shoe Fall can only be ascertained by the eye; the general opinion of those who have most frequently viewed it is, that it is not less than six hundred yards in circumference. The island which separates it from the next fall is supposed to be about three hundred and fifty yards wide; the second fall is about five yards wide; the next island about thirty yards; and the third, commonly called the Fort Schloper Fall, from being situated towards the side of the river on which that fort stands, is judged to admeasure at least as much as the large island. The whole extent of the precipice, therefore, including the islands, is, according to this computation, thirteen hundred and thirty-five yards. This is certainly not an exaggerated statement. Some have supposed, that the line of the falls altogether exceeds an English mile. The quantity of water carried down the falls is prodigious. It will be found to amount to 670,255 tons per minute, though calculated simply from the following data, which ought to be correct, as coming from an experienced commander of one of the King’s ships on Lake Erie, well acquainted in every respect with that body of water, viz. that where Lake Erie, towards its eastern extremity, is two miles and a half wide, the water is six feet deep, and the current runs at the rate of two knots in an hour; but Niagara River, between this part of Lake Erie and the falls, receives the waters of several large creeks, the quantity carried down the falls must therefore be greater than the foregoing computation makes it to be; if we say that six hundred and seventy-two thousand tons of water are precipitated down the falls every minute, the quantity will not probably be much overrated.
