To successfully steam a vessel up those streams against the remarkably swift currents, high-pressure engines had to be adopted generally. In that year, however, there were still a number of boats on the Mississippi and Ohio which, like the Champion, had low-pressure engines and the grotesque walking-beams.
It is a bewildering scene, with all these derricks thickly scattered around, engines noisily puffing, walking-beams forever rearing and plunging, the country cobwebbed with tumbling-rods and pipe lines, the shanties of the operatives with their rude lamp-posts, and the face of Nature so besmeared with the crude output of the wells that every twig and leaf is thick with grease.
Huge iron machines had their region, and trophies of cobweb lace theirs; while "walking-beams" clanked and shuttles flew, working wonders before amazed and enchanted-eyes. Especially never had there been seen, such modern triumphs in carved woodwork, in moulded iron, zinc, and bronze, in goldsmiths' work, in stoneware and porcelain, in designs for damasks in silk and linen.
The world was all ready to move, and only waited for a fresh supply of wheels, cranks, side-levers, walking-beams, and other such muscular creatures of iron, to push and tug and swing and revolve and set Progress a-going. Dunderbunk was to have its full share in supplying the demand. It was well understood by this time that the iron Wade made was as stanch as the man who made it.
A modern Samson, dumb as well as blind, its massive limbs of shining steel moved with voiceless grace and utmost apparent ease, driving the miles of shafting and the thousands of connected machines. The cylinders were forty inches in diameter; the piston stroke, ten feet. The great walking-beams, nine feet wide in the centre, weighed eleven tons each.
