For the ordinary carriage, here useless, was substituted a sledge, driven from behind by an instrument something between a paddle-wheel and a screw, worked, of course, by the usual electric machinery.

Two great, naked paddle-wheels were on the boat, one on each side near the middle.

The screw-propeller vs. the paddle-wheel for marine propulsion.

In 1833, or at the period now under consideration, however, the paddle-wheel was the recognized instrument of marine propulsion.

Some years earlier it appears that some of the objections to the paddle-wheel had become plainly apparent to Ericsson, although, occupied with other matters as he was, there was no immediate result.

He apparently recognized that the slow revolutions possible with the paddle-wheel did not favor the improvement of the steam-engine along the lines which have since been followed, and he saw clearly that for warship purposes the engines employed, exposed above the water-line to destruction from the shell of an enemy, were entirely out of the question.

So far as the screw-propeller was thought of as a means of propulsion, it lay under a suspicion of loss of efficiency due to the oblique nature of its action, and this was supposed to be such as to render it necessarily and essentially less efficient than the paddle-wheel.

A few years later it was recognized as an accepted mode of propulsion and had gained a permanent and definite place in the practice of the day,a place which has continued to grow in importance until its earlier rival, the paddle-wheel, is almost on the brink of relegation to museums of antiquities, except possibly for rare and special shallow-water uses.

The material used was wood, the means of propulsion sails, with some thought of steam-engines and paddle-wheels; the means of offence were cast-iron guns large in number but small in size, the largest being 9 or 11 inches in diameter and throwing a shell of some 75 or 130 pounds weight, while the means of defence consisted solely in the "wooden walls," and modern ideas regarding armor had not even appeared above the horizon.

So the paddle-wheels (at my desire) were lashed fast, and we are to see her opened to-morrow morning.

It was he who first applied steam to propel a vessel and navigated the Hudson for the first time with steam and paddle-wheels and vessel in 1807.

He merely adapted a steam-engine to a vessel armed with paddle-wheels.

They say the paddle-wheels knocked the" "And his wife?" gasped Andy.

The box which covers the paddle-wheel, &c., helps to make a break in this gallery, separating the gentlemen from the ladies.

Subsequently the "Royal William," built at Quebec, after running between that port and Halifax from 1831 to 1833, started in the fall of the latter year for Falmouth; and to her belongs the honour of being the first bonâ fide paddle-wheel steamer that crossed the Atlantic.

The oar, the helix, and the paddle-wheel constitute at present the means of propulsion that are exclusively employed when one has recourse to a motive power for effecting the propulsion of a boat.

The paddle-wheel was seen to be unsuited to such large fighting vessels, and there was no confidence in the screw; while the great majority of naval officers in France, as well as in England, were averse to any decrease in sail spread.

Kermit, Cherrie, and Miller squatted outside the railing on the deck over one paddle-wheel and put the final touches on the jaguar skins.

Paddle-wheel days in California.

Paddle-wheel days in California.

Paddle-wheels churning, the rotund boat swung into the Brooklyn dock.

The plain fact of the situation is that we're being hustled toward an amphibious thing with paddle-wheels named The Skylark, and I haven't said good-bye to you.

'Hashin,' say the paddle-wheels, slowing all of a sudden'MacNeill's Zarebathe 15th Sikhs and another native regimentOsman Digna in great pride and power, and Wady Halfa a frontier town.

It has been pleasant to trace upon the map the great arteries of intercommunication, flowing east and west, churned by countless paddle-wheels, as they force a vast freight of wealth, material, social, intellectual, to and fro, a freshet of fertilizing life to swell every stream.

"And to my intimates, every morning from twelve to two," she added very softly, with a dimpled smile that went straight to my heart, and set it beating like the paddle-wheels of a steamer.
