GRIMSBY-.—On the 6th March, at 2.30 P.M., the schooner Mary Coad, of Port Isaac, Cornwall, bound from Antwerp to Middlesbrough, was observed flying a signal of distress in the main rigging. She was riding in the Humber about half-amile N.N.W. of the Bull Buoy. The Lifeboat Manchester Unity was launched and proceeded to her assistance. With some difficulty, three of the crew of the Lifeboat boarded the vessel and found the captain and crew 'of four men in an exhausted condition. A steam-tug at this juncture endeavoured to tow the schooner up the river but failed to do so in consequence of the tow-rope parting. Three more of the Life-boatmen then boarded the vessel, got two tow-ropes out to the tug, and set the reefed stay and boom fore sails, these being the only two available sails. The schooner was thus got under weigh and taken to Grimsby Docks..
