In our ascending way up the mountain, we found the scenery altogether of a new, wild, and more rugged cast. Our ascent amid these vast summits,--the wonderful velocity with which we were borne--the ease with which we seemed to move through the gaps of the mountains, and over the tops of these everlasting hills--surrounded at every step by the most picturesque and gigantic elevations, appeared like the effect of enchantment. Then too as we moved upward a change was perceptible in the atmosphere--we felt its invigorating and exhilarating influence--and perhaps the new buoyancy, which our spirits acquired, helped to impart increased effect to the majestic scene that stretched around us, and had laid hold of our every sense and feeling with the power of a giant. Our course was still upward--upward! and all our train of cars still flew upward till we reached the very tops of the mountain wilds and fastnesses that stood in such majestic grandeur around us. It was announced at length that we had attained the summit height of the mountain. Just here the rivulets changed their course. The streams had all flowed eastward to empty themselves into the Atlantic, but now they turned westward and leaped forward, as though eager to find repose in the deep waters of the Mississippi. The Conemaugh, a tributary stream to the Kiskiminetas takes its rise here, and appears as a very little rill at its commencement. It was with peculiar emotions that I stood on the summit of the Alleghanies, and strained my eye to look off towards the vast valley of the Mississippi, whose western boundary is terminated by the Rocky mountains, a distance not less than 2500 miles.

What teeming millions are to be sustained by the products of this soil--are to live and die, and be prepared for heaven or for hell on the broad bosom of this valley! There is nothing but the gospel that can exert a saving influence upon the mass of mind congregating here, and make this far outspreading and fertile region the abode of moral beauty and the home of civil freedom. The gospel planting her foot here, and stretching her arms over the whole extent of this western valley, must wake up holy affections, and songs of praise to the sin-conquering Lamb, all along the banks of these thousand streams, or the blight of desolation will fall here--and the fairest portion of God's earth will be withered by the scorching fire of human passion--and bathed,
