SWANAGE.—On the, 7th January, a messenger arrived from Studland stating that a vessel was in distress near the entrance to Poole Harbour. The Life-boat Charlotte Mary was at once launched and proceeded to the spot, when it was found that the ketch Effort, of Portsmouth, had parted from her anchors and gone ashore, the sea making a complete breach over her. The Life-boat, with great difficulty and danger, succeeded in rescuing the crew of 2 men and landed them at Poole..
