ALDEBURGH.—On the morning of the 1st November the coastguard on duty reported that guns were being fired and signal flags shown on board a vessel aground on the Shipwash Sands. A strong N.W. breeze was blowing, theTe was a moderately rough sea, and the weather was hazy. The Life-boat George Hounsfield was launched at 8.40, and on reaching the vessel found her to be the schooner Sensation, of and for Dover, coal laden from the north. The crew of a smack had been engaged to get the vessel off, and the Life-boat remained by her until she floated at high water..
