Langdon's Patent Horse Power Machinery.--We think it both just and proper to state the following facts, respecting the Machinery of Mr. Langdon, in order to induce persons needing the Horse Power, (which can be applied equally easy to almost any description of mills,)--to apply to Mr. Langdon; inasmuch, as Mr. L. has recently met with a most severe and discouraging misfortune, in having his works destroyed by fire, at Troy. With a spirit unbroken by that calamity, he immediately renewed his establishment, and is now or very soon will be, in readiness to execute orders.
The horse-ferry boat Cossack, the machinery for which was made by Mr. Langdon, has been in operation, for more than two months, and performs to the entire satisfaction of her proprietors and the public. She is moved by the power of four horses, and crosses from our pier to the wharf of Col. Warren at Waterloo, the distance of 3-4ths of a mile, across a current of 6 miles an hour, in the short space of four minutes!
Quick Trip.--The Steam Boat Niagara, capt. Pease, left this port for Detroit, on Thursday evening last, and returned on Tuesday morning, touching at all the ports on her passage up: and at all on her passage down, excepting Cleaveland and Dunkirk; thus accomplishing her trip both ways in 4 days and 13 hours, including her stay at Detroit, which was 21 h'rs. This we believe is the quickest trip ever made on lake Erie.
The Niagara proves to be a most admirable sea vessel and in point of speed ranks with the swiftest boats on these waters. We have heretofore spoken of her as being the handsomest both in model and finish. Her engine is of superior workmanship, and for its dimensions is one of great power. It was made by Mr. Langdon, who is noticed in the above article.
