Valuation of the several towns and cities in the State as returned by the town and city clerks to the Secretary of State, October, 1875. The Corliss Engine AT THE INTERNATIONAL EXPOSITION. THIS engine was furnished by George H. Corliss, of Providence, Rhode Island, and was especially designed for supplying motive power at the International Exposition of 1876. This engine is of fourteen hundred horse-power, but is capable of doing the work of twenty-five hundred horses if necessary. With its appurtenances it weighs over seven hundred tons, and furnishes power to all the machinery in the building, Miles of shafting lead away from it along the aisles from end to end. Of these are eight main lines of shafting, four on each side of the central transept where the engine stands, extending lengthwise. Seven have a speed of one hundred and twenty revolutions, and one a speed of two hundred and forty revolutions a minute. A line of shafting is also provided for carrying power into the pump annex, and counter shafts are introduced into the aisles at different points. The power is transmitted by the spur-gear fly-wheel, thirty feet in diameter, weighing fifty-six tons; the jack-wheel ten feet in diameter on the main shafting, which being run under the floors to the pulleys, the power is transmitted thence to the eight main lines of shafting above the floor, aggregating more than a mile in length, from which the machinery of the Exposition derives its power. The engine makes thirty-six revolutions per minute, and for driving them there are twenty Corliss boilers capable of developing fourteen hundred horse-power, and of standing a pressure of one hundred pounds to the square inch. The platform on which the engine stands is breast high. From this, on either side, a long iron staircase mounts to the top of the A frames, where narrow walks with brass railings lead about among the moving masses aloft in the air. It is five times a man's height from the platform to the top of the walking-beam. It is a tamed monster with unresistable power. To see a man walk calmly around among the great beams and cranks is a sight to make one shiver. He caresses a polished crank of steel that would crush him to bits if he should stop in its path. He pats the ends of the beams as they fly up and down past him, and touches the joints with his oiler. Aside from the fact that the engine is one of the largest of its kind, it is so unique in construction and form that it is all new to beholders. It is a model of simplicity and picturesqueness.
