than at the rate of two miles an hour--certainly not nearly so fast as we could have walked, so that we had full leisure to contemplate the chasm into which we should have been plunged headlong had the slightest slip of the wheels occurred. How they can ever venture to pass it at night is quite surprising. The curve is like a horse shoe, and goes round the face of a rock which has been cut away to make room for the road. Another superiority in the road we travelled to-day is the much greater height of the surrounding mountains, and the extent of the distant views;--but the greater height of the mountains had the attendant disadvantage of the trees being chiefly pines, instead of the lovely forest trees, of every description, which adorned the hills amongst which we travelled in Maryland and Virginia, by the Baltimore and Ohio railway. I must, however, do justice here to the eastern side of the mountains. For more than 100 miles we closely followed the course of the Juniata, from its source to where it ends its career by falling, quite a magnificent river, into the Susquehanna, about twenty-two miles above this place. After the junction, the noble Susquehanna was our companion for that distance, this town being situated upon it. The source of the Juniata is seen very soon after passing Altamont, and perhaps we were more disposed to do justice to the beauty of the river, from the happy frame of body and mind we were in, owing to the excellent dinner we had just partaken of at that place, consisting of roast beef, roast turkey, apple tart, cranberry preserve, and a most superlative Charlotte Russe--pretty good fare for an hotel in a mountain pass! No wine or stimulants of any kind were allowed, or what the consequence might have been on papa's restless state of mind it would be difficult to say; as it was, I counted that he rose from his seat to look at the view from the other side of the car, thirty times in the space of an hour and a half, making a move, therefore, upon an average, of once in every three minutes; and this he afterwards continued to do as often as the road crossed the river. I foolishly, at first, partook of his locomotive propensities, but my exhausted frame soon gave way, so that he declares I only saw one half of its beauties, namely, the half on the side where I was seated; but this half was ample to satisfy any reasonable mortal. I am at a loss to imagine what our fellow-travellers could have thought of him, as they lounged on their seats, and scarcely ever condescended to look out of window.
