NEW STEAMBOAT. - A little steamboat, named the GEM, built at Newport, during the past winter, by Messrs. J.E & W.C. Dixon, for Mr. W.P. Campbell, of Detroit was towed into Detroit yesterday. Her dimensions are, length of keel, 60 feet; breadth of beam, 15 feet; depth of hold, 5 feet 8 inches. Her engine will be put in immediately, and she will commence her trips in about four weeks. She is to be commanded by Capt. John B. Goodsell, and will run between Detroit and Grosse Isle, touching at Wyandotte. Her model is much praised by the "knowing ones." - Detroit Free Press
