Peter P. Wright's New Tug. - The new steam tug "H. Perry, Jr." made a short experimental trip yesterday morning, on the Lake. her boiler had been fired up but a few times, and owing to the "foaming" only a small head of steam was raised, not exceeding thirty pounds, and sometimes below that, while her ordinary head when in running order will be about sixty pounds.
The performances of the tug, however, came fully up to expectations, and the engine worked admirably, and will reflect great credit upon its manufacturers, Messrs.. Talcott & Underhill. It works very smoothly, and new as it is, scarcely a jar is felt, and when her "bearings" are set up snug there will be still less. There are some advantages and improvements in the engine and boiler not usually found in those of this class.
The crank shaft is a solid piece of wrought iron, and has but two bearings, thus saving friction and securing simplicity and convenience; the head of the steam chest is set on the side and can be removed in a few moments, rendering any difficulty in the valves readily accessible, and avoiding the loss of time in such emergencies; and a great improvement is the saving in friction at the head of the propeller shaft, which runs on a small pivot the size of a half dollar, and is kept constantly lubricated by an oil cup and a piece of wicking, thus also saving time and trouble in oiling.
The boiler also has several improvements, and is in all respects of very superior make. We think this boiler and engine of the Perry will prove the ability of Messrs. Talcott & Underhill, to turn out as good marine engines as any other establishment in the interior. When the Perry is in good running order, she will show what she can do.
