ON Friday evening, the 29th of November, 1830, the St. George, a first-class steamer, commanded by Lieut. TUDOR, R.N., arrived at Douglas, Isle of Man, with the mail from Liverpool, and anchored in the bay. The night was stormy, with heavy gusts of wind from the S.W., which towards morning came round to the S.K., blowing direct in, and soon increased to a tremendous storm.

About 5 A.M. the chain cable of the St. George gave way, when she began to drive in between the Pollock and St. Mary's (or Conister), two equally dangerous rocks under her lee.

The steam had been, kept up all night, with the men at their stations; but the vessel was so near to the rocks, and the force of the waves so overwhelming, that in attempting to back her out she struck violently upon St. Mary's, immediately filled, and settled down forward, with her head to the land, lying nearly broadside to the most rugged part of that fatal rock, from which few vessels that once strike ever escape.

Lieut. TUDOR immediately ordered the foremast to be cut away, with the view of forming a raft, by means of which the people might gain the rock, and from thence, though covered at high water, he hoped when the day dawned they might be rescued off the lee-side by boats from the shore; but this was found impracticable. Signals of distress were also made.

Sir WM. HILLARY, receiving speedy intimation of her danger, proceeded to the pier, and immediately put off in the life-boat, accompanied by Lieut. ROBERT ROBINSON, R.N., Mr. WM. CORLETT, agent to the St. George's Company, his coxswain ISAAC VONDY, and a volunteer crew of 14 boatmen.

On approaching the St. George the anchor of the life-boat was let go to windward, and by veering down upon the wreck, an attempt was made to take off the people from the weather quarter; but the surf was Found to be so violent as to render that plan xj, racticable. It was therefore resolved, at -a., hazards, to back the boat in between the St George and the rocks, when Lieut.

TUDOR, with the self-devotedness of a British seaman, entreated of them not to attempt his rescue by means which he found would be attended with inevitable destruction.

It was, however, persevered in, and with great difficulty accomplished; but the sea inside rolled so heavily, that the boat was in danger of being instantly demolished.

Her rudder was beaten off, 6 out of her 10 oars broken or lost, some of her air-tight cases and her upper works much injured, and Sir WM. HILLARY, Mr. CORLETT, and two boatmen washed overboard. Mr. COR- LETT and the two men were fortunately soon got into the boat; but Sir WM. HILLARY, being unable to swim, providentially seized a rope which hung from the vessel's side, by which he supported himself in the waves until Lieut. TUDOR, assisted by Lieut. Roam-SON, who had gained the wreck with much difficulty, got him also on board, considerably bruised and hurt.

From the disabled state of the boat and the loss of the oars, it became impossible to take off the people and extricate themselves, by hauling up to her anchor to windward, as was originally intended. All passage to leeward was obstructed by the rigging of the mast, which had now been cut away.

Thus hemmed in between the wreck and St. Mary's rock, on which the surf broke tremendously, the situation of the crews of the St. George, and of the life-boat alongside, remained for nearly two hours equally critical and perilous.

At length, by much labour and hazard to the men employed, the rigging of the fallen mast was cut away by means of knives, and an axe which fortunately was in the boat.

As the tide rose the sea increased, and every* wave now swept the decks of the St. George, and nearly buried the life-boat; it therefore became requisite to make a last effort to extricate themselves from a situation, where longer to have remained must have proved fatal to all. The crew of the St.

George consisted of 22 persons ; that of the life-boat of 18. They were all got into the boat. The water was baled out by buckets obtained from the vessel; the remaining oars manned. The boat was then cast off, and the cable veered away; but she struck violently on the low ridge of rock, filled, and striking again, was at length, by the violence of the breakers, washed over the reef, the people holding on by ropes. The cable was then cut, and the sea coming round the bow of the St. George, drove the boat broadside on upon the sheltered side of St. Mary's, being thus, through a merciful providence, delivered from the awful situation in which they had been so long placed.

They then proceeded for the shore, about a quarter of a mile distant. They were met by two boats, which had put off and approached them under shelter of the lee of the rock, one boat relieving them, from some of the people; the other, brought out by Lieut. SLEIGH, E.N., promptly gave a tow- line to the life-boat, and assisted her in making the beach, which she reached in a shattered condition, but saving all her crew.

The steamer went to pieces where she struck, a loss to the owners of 12,OOOZ. The Shipwreck Institution awarded for this gallant service a gold medal each to Sir WM. HILLARY and to Lieut. ROBINSON ; a silver medal each to Mr. CORLETT and ISAAC VONDY, coxswain; and 212. to the boat's crew. The St. George's Packet Company also gave the crew 5QL for their praiseworthy exertions on this occasion.
