The Steam-Boat building at this place, by the proprietors of the Pioneer, is in a state of forwardness.
We learn by Capt. Wilkinson, of the schooner Guerrier, who arrived her on Friday last from Detroit, that on passing a small island called the West Sister, on the 4th instant, his attention was attracted by a signal, and on arriving at the island, he found two men and one woman, who had been there five days and nights, subsisting entirely upon roots and herbs. It appears the schr. Morning Star, Captain Costelo, of Sandusky, ran on a reef of rocks, near the island, about 12 o'clock at night. Apprehensive of danger, all on board took to the boat and safely reached the shore. The next morning, the schooner being in sight, at no great distance, the captain and one of the sailors put off to her for the purpose of obtaining provisions and ascertaining her condition, neither of whom returned, and are supposed to be lost. The schooner has since been discovered, keel upwards, between the islands and Amherstburgh. The three persons left on the island were taken on board the Guerrier, and landed at Sandusky. They succeeded in attracting the attention of Capt. Wilkinson, by raising a shirt on a pole; and their joy at their deliverance can be better conceived than described.
