MONTROSE, N.B..—On the llth April, at 2 P.M., when blowing hard from the N.E., the schooner Charm, of Montrose, bound from that port to Hartlepool, got ashore at the entrance of the river, and subsequently became a total wreck. The Lifeboat Mincing Lane at once proceeded to her assistance, and removed the crew of 3 men. The master, after the Life-boat had stood by the wreck for half an hour, resolved to stay by her, and subsequently escaped at great personal risk by swimming and climbing over the rocks..
