LIGHT HOUSE.--Mr. Warren, of Rochester, N.Y., who contracted to build the Light House at Fort Gratiot, immediately at the outlet of Lake Huron, has completed that work, and on the evening of the 8th inst. it was, for the first time, lighted up. The light is represented as being very good. The danger of approaching in the night the entrance of the River St. Clair, from Lake Huron, particularly in a high wind, has always been represented as being very great, in consequence of the many bars, and of the difficulty of discovering the proper point at which to enter the river. Mr. Rufus Hatch has been appointed keeper of the Light House.
HORSE BOAT.--The Horse Boat, recently built at Cleaveland, O. by Capt. John Burtis, arrived here last Friday evening. She is about 50 feet in length and 32 in width, firmly built, and is represented to us as being very well calculated as a ferry boat. We learn that the boat was built for the purpose of ferrying on our river at this place, but that the owner will remove her, unless sufficient encouragement should be given to pay him in a measure for his expenses. It is to be hoped that some steps will be taken by the citizens of Detroit to retain this boat here. The necessity for a ferry oat, such as this is represented to be, is great and has long been felt.
We have been requested to inform the citizens of Detroit that a meeting will be held at Woodworth's on Saturday next, at four o'clock, P.M. to take into consideration the above subject.
***The above Boat will leave Berthelet's wharf at 4 o'clock, each afternoon, to accommodate sailing, parties. She has a well furnished bar, and many conveniences to accommodate parties.
