To me it seemed astonishing, that intelligent men, who knew any thing of the scriptures, could hold the views that had been broadly expressed, and yet suppose that they were not infidels. I was more than ever convinced that men might be learned in science, in law, in medicine, in politics, and yet be profoundly ignorant of the great design and prominent features of the gospel. CHAPTER IV. PITTSBURG AND ITS ENVIRONS. First view of Pittsburg--Its general aspect--Sabbath and its employments--An affecting incident--Orphan children--A Christian father in the midst of his children on the Sabbath. _Saturday Evening, June 17._ About nine o'clock this morning, we passed the Alleghany river just above the point where the Kiskiminetas falls into it; our course thence was along the banks. The scenery on either side of this river, like that of all the other rivers we have traced, is very interesting. Its waters seem clear and transparent, and the banks are beautifully over-hung with trees of a rich dark foliage. It was about three o'clock, P. M., when we caught the first view of Pittsburg. The day was unusually bright and sunny, and the atmosphere uncommonly clear, and our Pittsburgian friends congratulated us upon having so favorable a time in which to take the first view of their city. I was aware that the hills that encompassed this city were filled with bituminous coal, and that one great source of its wealth and prosperity were the factories moved by steam power which could be employed with great effect and cheapness, in consequence of the abundance of this coal. I was also aware that this article constituted the principal fuel which warmed their houses. I therefore expected to see a _smoky city_, but I was not prepared to see what actually, at first sight, burst upon my view--a vast cloud of smoke rolling up in ten thousand dark columns, and forming a dense, murky canopy, that hung in expanded blackness over the whole town. The city seemed in its sooty and blackened houses, and in its columns of everlasting smoke, like one vast and extended group of furnaces or glass-factories. As I continued to gaze upon it, I was reminded of the smoke that went up from the plain of Sodom the morning after the destruction of that city, "when Abraham gat up early and looked over the whole plain." Our nearer approach to the city did not relieve me from my first impression. Every object and scene, every house and building within the purlieus of the town seemed stained, soiled, and tarnished with the sooty vapour that was ceaselessly ascending from its ten thousand chimneys. Like the frogs of Egypt this dreadful smoke came up into their houses, and there was no escape from it. The walls of the most elegant drawing-rooms bore evidence that the discolouring element had found its way there. The atmosphere every where seemed impregnated with it. I raised the window in
