For some years those interested in such matters almost despaired; but there is a brighter outlook ahead now. The great lake fleet of steamers and sailing vessels has vastly increased. The tonnage passing through the Sault de Ste. Marie is really greater than our whole ocean tonnage of forty years ago: and the improvement in the quantity and size of merchant vessels built during the last few years for ocean service, while not keeping pace with the lake traffic, on account of foreign competition, is still very gratifying.
We have already spoken of the ability shown by Americans, during the last few years, to produce the best armor in the world, guns equal to any, and war-ships of the very first class, in hull and machinery.
This is all a preparation and education for taking our proper place as builders of the very best merchant vessels. Builders could not afford the extensive apparatus and machinery necessary for such construction unless they had been encouraged by government orders in the beginning. Such works as those at Bethlehem, in Pennsylvania, would never have constructed the largest steam-hammer in the world, if it had not been for the encouragement afforded by government orders. Now they are prepared to forge shafts, and other great pieces, for the largest merchant steamers, for the obtaining of which we formerly had to send abroad.
As for plants for iron or steel ship-building, we now have many. Cramps’ establishment, in Philadelphia, is said to be the third largest in the world—and will soon rank higher; there are other great works for merchant vessels on the Lakes and the Mississippi, and at Newport’s News, near Hampton Roads. After these come the works at South Boston and the different establishments at New York. The purely naval building-yards and plants at the New York navy yard, and at Norfolk, are well known; while the Union Iron Works at San Francisco have turned out some of the finest vessels afloat, both men of war and merchantmen. There are also such works in Bath, Maine.
But the least effect of these great plants is shown in their production up to this time. They are not only educational to ship and engine builders, but they foster a number of most valuable trades—such as ship-carpenters, plumbers, copper-smiths, joiners, and many others. Above all come the naval designers or architects. Men so trained are well paid, and are required to turn out the very highest grade of work; and thus we are forming a force, at many points of our great country, fitted, when the time comes (and it must soon come), to build up our sea-going mercantile marine to an equality with the sister service on the Great Lakes, so as to enable it to carry our products abroad, and bring back the returns, without depending upon foreign bottoms for that service. A few years ago there was no place in this country where a young man could go to learn the business of designing and building iron vessels—now there are many such places—and they are constantly increasing in number.
MACHINERY.
Not the least wonder of our day is the improvement in the machinery of steam-vessels of all kinds.
The engineer’s department of a first-class cruiser or battle-ship is a bewildering and wonderful sight to one not accustomed to it. The complicated engines, with their numerous cylinders, which use the steam over and over, seem almost too delicate, and too like a fancy creation, to be capable of driving the propellers at such a rate as they do. Instead of the rude levers of former days, these giant machines are managed by the turning of wheels which look like playthings as compared with the forces which they control so easily.
The boilers not only serve to drive the main engines, but there are others devoted to different uses; among which the principal are the distilling of salt into fresh water, and thus giving an abundant supply of one of the very first necessaries of life, and rendering the vessel and the crew independent of the shore in that respect. It is also most conducive to health; for much of the disease found on ship-board, within even recent times, was due to the character of the water obtained from the shore. Then there are the electric dynamos, and their boilers which must run when the ship is at anchor, as well as when she is under weigh; while her steam steering-gear, when in motion, renders her guidance very easy in the hands of one man, when four or six would be required at the wheels of vessels in the old days.
