PORT ISAAC, CORNWALL.—On the 26th March, at about 1 P.M., the schooner British Queen, of Wexford, bound from that port to Porthcawl in ballast, was observed to be in distress. The wind was blowing a strong gale from the N.N.W., and there was a heavy sea running. The crew of four men were seen to leave the ship about a mile off the shore in their own boat. The Richard and Sarah Life-boat was at once launched, and after about an hour's pull rescued the crew when they were within a hundred yards of the cliff, where escape would have been impossible..
