The line westward from Lancaster crosses one long ridge-like hill after another stretching broadly over the country, and finally comes to the outlying ridge of the Allegheny range, the South Mountain, beyond which is the great Appalachian Valley. One railroad route boldly crosses this mountain through the depressions in the Conewago hills, where the picturesque Conewago Creek, the Indian "long reach," flows down its beautiful gorge to the Susquehanna, and this railroad finally comes out on that river at Middletown below Harrisburg; the other route follows a more easy gradient westward ten miles to Columbia, and this is used by the heavier freight trains. Coming towards it over the hills, the wide Susquehanna lies low in its broad valley, enclosed by the distant ridge of the Kittatinny bounding Cumberland County beyond the river. As it is approached, the thought is uppermost that this is one of the noblest, and yet among the meanest rivers in the country. Rising in Otsego Lake in New York, it flows over four hundred miles down to Chesapeake Bay, receives large tributaries, its West Branch being two hundred miles long, rends all the Allegheny Mountain chains, and takes a great part of the drainage of that region in New York and Pennsylvania, passes through grand valleys, noble gorges and most magnificent scenery, and yet it is so thickly sown with islands, rocks and sand-bars, rapids and shallows, as to defy all attempts to make it satisfactorily navigable excepting by lumber rafts, logs and a few canal boats. Thus the Indians significantly gave its name meaning the island-strewn, broad and shallow river, and it is little more than a gigantic drain for Central Pennsylvania.
