LAUNCH OF THE NEW PROPELLER A. C. VAN RAALTE YESTERDAY AFTERNOON - We witnessed the launch yesterday afternoon of a new and handsome little propeller of 200 tons burthen, at the yard of Messrs. Hitchcock & Gibson, foot of Erie street. Promptly at 3 o'clock, the hour announced for the launch to take place, the new vessel, with flying colors, was "let slide," and away she went into the water, as smoothly and gracefully as a duck. On a white flag, with red letters, was the name of the new steamer - A. C. Van Raalte. About two hundred persons were present to witness the launch. This neat and rakish-looking little craft was built for John T. Edwards, Esq., of St. Joseph, Mich., and is to ply between Holland, St. Joseph and Chicago. She is of comely proportions, and she has the new concave guards, instead of the old square ones. Her engine was built by Messrs. Farrar, Trefft & Knight, is high pressure, and 20 x 21. She has 95 feet length of keel, 23 feet breadth of beam, and 9 feet depth of hold. Her cost is $20,000. It is confidently expected by her builders that she will make fourteen knots an hour (sic) easily, and it is calculated that she will be second to none in point of speed. She was named after the founder of a colony of Hollanders - A. C. Van Raalte - in Michigan. This propeller reflects credit on her builders, who laid her keel on the 1st of September last, being just two months and a half in completing her. When launched, she had everything on board except her smoke-stack. The Van Raalte will leave on Monday for her destination. This makes the third propeller the builders have contracted for the same parties since the opening of navigation. - [Buffalo Commercial Advertiser.
