CAISTER.—On the 12th November, at about 11.40 A.M., the brig Lavinia, of Guernsey, bound thence to Sunderland, in ballast, was seen to be between the Scroby and Cross Sands with colours flying union downwards. The Covent Garden Life-boat proceeded to her assistance, and fonnd her riding with both anchors down, but one cable had parted; she had three feet of water in her hold, and her ballast had shifted to the lee side. The Life-boatmen dared not board the vessel while at anchor, the sea being too heavy, they therefore shouted to the crew to slip the cable, and boarded her while under weigh.. The brig was taken between the Scroby and Cross Sands, a steam-tug was engaged, and she was towed into Yarmouth Harbour. She had stranded on the Hasborough Sands on the previous night..
