Of course the greatest skill is required in driving the engine up what is called the "Mountain Division." We mounted on the locomotive, to have a more perfect view of the ascent. This locomotive is very different to an English one, as the place where the driver sits is enclosed on three sides with glass, so as to shelter him and those with him from the weather. Mr. Tyson thought it necessary to drive a small part of the way himself; but after that, he resigned his position, as will be seen by the following certificate, to one equally qualified for an emergency, though hitherto his peculiar talent in that line had not been developed. "Baltimore and Ohio Railway, Machinery Department. "Baltimore, Oct. 21st, 1858. "This is to certify that Mr. A. T. has occupied the position of 'Locomotive Engineer,' on the _Mountain Division_ (3rd) of the Baltimore and Ohio Railroad. "The term of his occupation has been characterised by a close attention to his duties, and consequent freedom from accidents. (Signed) "HENRY TYSON, "Master of Machinery, "Baltimore and Ohio R. R. Co." Papa, in fact, drove the engine a considerable way up the steepest part of the ascent, and as the driver must command an uninterrupted view of the road before him, he had a capital opportunity of seeing the country. Thrower and I sat on a seat behind him; but he alone had the full view, as the chimney of the engine rather obstructed ours in front, though on each side we saw perfectly. The whistle of the engine, when so close to our ears, was splendid, or perhaps you would have said, terrific. From Altamont to Cranberry Summit, where the descent begins, there is a comparatively level country, called the Glades, which are beautiful natural meadows undulating and well cultivated, with high ranges of mountains, generally at no great distance from the road, but varying a good deal in this respect, so as sometimes to leave a considerable plain between it and the range. From these glades numerous valleys diverge, and, in looking down these, splendid vistas are obtained. The verdure even now is very bright, and the streams, which are everywhere to be seen, are remarkably clear and pure; so that although the interest of the road was less absorbing than when we were ascending the mountains, it was still very great. From Cranberry Summit the distant views to the westward were quite magnificent.
