FALMOUTH, CORNWALL.—At 8 P.M. on the 4th February the Life-boat Sob Newbon was launched, intelligence having been received from the coastguard that a vessel was aground on the Black Rock. A moderate wind was blowing from E.N.E., and there was a moderate sea. On reaching the vessel she was found to be the schooner Snaefell, of Ramsey, Isle of Man, bound from Portmadoc for Ipswich, with a cargo of slates. It appeared that in entering the harbour she had to alter her course in order to avoid collision with another vessel and ran on the rock. When the tide served she was taken by a steam-tug to a safe anchorage, the Life-boat standing by her until all danger was over..
