IMPROVED STEAM CANAL BOAT.

The late experiments in canal steamboats bid fair to be a complete

success. The Baxter steamers were not sufficiently remunerative

to continue the building of that kind of boat. They do not carry a

sufficient load, owing to their build, and that is made necessary by

the form and arrangement of the machinery and propelling power, the

propeller being that form used by the tug in Buffalo. The new style,

which bids to pay handsomely, is as full a bow and stern as the

ordinary first-class canal boat. The propelling power is radically

different from the tug propeller. The wheel is eight feet in diameter

and placed close to the stern; the boiler is upright, with a single

engine, very compact machinery, taking up no more room than the stable

in many boats, and enabling the boat to carry 7,500 bushels of corn

and coal for the trip. With this cargo they run from Buffalo to New

York in seven days on five and a half gross tons of coal, saving river

and harbor towing. One returned from New York to Buffalo in one hour

less than seven days, bringing one hundred and thirty tons of freight.

The outlook now promises to supersede mule and horse towing. The

Belgian system of cable towing will take that large number of boats

now relying on the mule, and deliver them promptly as consigned and in

much less time and cost than can be done by the mule. Both systems are

necessary for rapid movement on the canal, and to cheapen the transfer

from the West to the seaboard. Steam is sure to supersede animal power

on the canal, as everywhere else. The canal steamboats are at last so

far perfected as to insure a handsome profit in running them, and

a large number will soon be at work on the canal. Two are to be

constructed in Lockport as speedily as possible by one of our most

enterprising boat builders, and the machinery is contracted for,

thus opening up a new industry for our numerous and worthy

mechanics.--_Lockport_ (_N. Y._) _Journal_.
