CAISTER.— At 9 P.M. on the 13th October, the No. 2 Life-boat Godsend was launched during a strong gale from the N. and a very heavy sea, signals of distress having been shown by the schooner Emperor, of Banff, and the three-masted schooner Girl of Devon, of Plymouth, which had been in collision in the north part of Yarmouth roads. The Life-boat went first to the Emperor, the master of which stated that he required assistance, but as his vessel was not sinking, he requested the Life-boat men to go to the other vessel, which, they did, and at the master's request, assisted to clear away the wreckage, remaining by her all through the night. At midnight a tug arrived from Yarmouth, and was hailed by the coxswain of the Life-boat, and sent to the assistance of the Emperor, which she towed into harbour. In the morning the weather moderated, and the Life-boat took the master of the Girl of Devon ashore to telegraph to the owner of the vessel for instructions..
