Mr. Weld observes that it is possible not merely to pass to the very foot of the great fall; but even to proceed behind the tremendous sheet of water which comes pouring down from the top of the precipice; for the water falls from the edge of a projecting rock, and, by its violent ebullition, caverns of considerable size have been hollowed out of the rocks at the bottom, and extend some way beneath the bed of the upper part of the river. Mr. Weld advanced within about six yards of the edge of the sheet of water, just far enough for him to peep into the caverns behind it. But here his breath was nearly taken away by the violent whirlwind, that always rages at the bottom of the cataract, occasioned by the concussion of such a vast body of water against the rocks. Indeed Mr. Weld had no inclination either to go further, or to explore the dreary confines of these caverns, where death seemed to await any one who should be daring enough to enter their threatening jaws. No words, he says, can convey an adequate idea of the awful grandeur of the scene, at this place. The senses are appalled by the sight of the immense body of water that comes pouring from the top of the precipice; and by the thundering sound of the billows dashing against the rocky sides of the cavern below. He trembled with reverential fear, when he considered that a blast of the whirlwind might have swept him from off the slippery rocks on which he stood, and have precipitated him into the dreadful gulph beneath; whence all the power of man could not have extricated him. He here felt what an insignificant being man is in the creation; and his mind was forcibly impressed with an awful idea of the power of that mighty Existence, who commanded the waters to flow.] Fourth Day's Instruction. UNITED STATES CONTINUED. _Narrative of Lieutenant_ HALL'S _Journey from Niagara to Philadelphia._ Mr. Hall crossed the river from _Fort Erie_, and proceeded to _Buffalo_, one of the frontier villages which had been burnt during the great American war. Not a house had been left standing; yet, when Mr. Hall was there, it was not merely a flourishing village, but a considerable town, with good shops and hotels. The celerity with which Buffalo had risen from its ashes, indicates the juvenile spirit of life and increase, which so eminently distinguishes the American population. As Mr. Hall proceeded on his journey, he found the country thickly settled, but dull and uniform in feature; being an entire flat. The autumn had been dry, and water was, in many places, extremely scarce. This is an evil not uncommon in newly-settled districts. Draining follows clearing; the creeks, no longer fed by the swamps, disencumbered also of fallen trunks of trees, and other substances, by which their waters were, in a great degree, stayed, easily run dry in summer, and soon fail altogether.
