PENZANCE. — The brigantine Jeune Hortense, of Nantes, bound from Brest for Fowey, in ballast, dragged her anchors during a heavy ground sea on the 17th May, and drove ashore on the Eastern Green just under the Long Rock. The Dora Life-boat was launched about 5 P.M., and after a hard pull of about a quarter of an hour through heavy broken water, succeeded in getting alongside the vessel, took off three men and a boy, and brought them safely to land.
