The question was referred to Benjamin H. Latrobe, the most eminent engineer in America, and his report was published approvingly in the Transactions. "A sort of mania," wrote Mr. Latrobe, "had indeed prevailed and not yet entirely subsided, for impelling boats by steam-engines." But his scientific hearers would at once see that there were general objections to it which could not be overcome.
At the present time it is not precious metals solely which should fix the attention of new mining companies; the multiplication of steam-engines renders it indispensable, wherever wood is not abundant or easy of transport, to seek at the same time to discover coal and lignites.
"Our ship is crowded with engineers, and operators, and delegates from the Governments of Russia and France, and the deck is a bewildering mass of machinery, steam-engines, cog-wheels, breaks, boilers, ropes of hemp and ropes of wire, buoys and boys, pulleys and sheaves of wood and iron, cylinders of wood and cylinders of iron, meters of all kinds, anemometers, thermometers, barometers, electrometers, steam-gauges, ships' logs from the common log to Massey's log and Friend's log, to our friend Whitehouse's electro-magnetic log, which I think will prove to be the best of all, with a modification I have suggested.
His whole mental atmosphere was thronged with spectral enginery; wheel within wheel; plans of hugest mechanism; Brobdignagian steam-engines; Niagaras of water-power; wind-mills with "sail-broad vans," like those of Satan in chaos, by the proper application of which every valley was to be exalted and every hill laid low; old forests seized by their shaggy tops and uprooted; old morasses drained; the tropics made cool; the eternal ices melted around the poles; the ocean itself covered with artificial islands, blossoming gardens of the blessed, rocking gently on the bosom of the deep.
This Rolling Mill consists of two combined steam-engines, acting on cranks at right angles, the reversing of the rolls being effected by the link motion. The requisite rolling power is obtained by suitable wheel and pinion gear, so as to be entirely independent of the momentum of a fly-wheel, which is entirely dispensed with. I did not patent the invention.
Boiled cotton-seed is fed to hogs on all plantations, but it is far behind corn in nutritious and fattening qualities. Cotton-seed is packed around the roots of small trees, where it is necessary to give them warmth or furnish a rich soil for their growth. To some extent it is used as fuel for steam-engines, on places where the machinery is run by steam.
Here, closing my eyes on the sloops, lighters, and schooners lying at no great distance, and barring my ears against the cries of busy carmen and wharfingers, and the clanging of steam-engines, I calmly set about surveying in my mind's eye the group which ready imagination conjured up in colours, if not as true, at least as glowing, as the by-gone reality.
Ploughing, except on steep hillsides and in very stony ground, can be cheaply and effectively done by steam. The same agent can propel the harvesters and work the threshing machines. Even farmers who till fields of no great extent find it desirable to do much of their work by steam-engines, for the reason that fuel is less costly than horse feed.
Besides the manufactures we have enumerated and described, there are many others of more or less importance; and new inventions and the spur of enterprise are creating new manufactures in Birmingham every day. There are manufacturers of steam-engines and other machinery, of stoves, grates, and other iron foundry. Pugin. Another executes stained-glass windows.
Try and picture to yourselves that on the east coast of Northumberland and Durham, where all is now black with coal- dust, and grimy with the smoke of furnaces; and where the noise of hammers and steam-engines, and of carts and trucks hurrying to and fro, makes the country re-echo with the sound of labour; there ages ago in the silent swamp shaded with monster trees, one thin layer of plants after another was formed, year after year, to become the coal we now value so much.
