j NEW YORK, July 11. Struck by a tidal wave, which it is supposed was produced by a submarine earthquake, the British tramp steamer Sir Richard Grenville was almost engulfed on Sunday afternoon while 300 miles outside of Sandy Hook. The ship reached the Upper Bay to-day, minus her funnel, which was washed overboard by an enormous wave. Lifebuoys were smashed, ventilators are gone, and the main deck is a complete wreck. One of the strangest features of the wave is that after the water on the deck had subsided a piece of a spar, supposed to be the yard-arm of some wrecked vessel, with many pieces of lumber, was found on the main deck. The only ? explanation of this Captain Jones volunteered to make was that a submarine earthquake released part of a sunken vessel from the bottom of the ocean. Captain JonH rigged a jury funnel of scantling and lumber. ' The improvised funnel was a box-like affair, ! eight feet adroiss, rising ten feet above : the deck. The sparks and flames from the furnao© nearly overpowered the men, and a bucket brigade had to b.e stationed near the funnel to prevent i the ship catching fire. The Sir Richard ' Grenville came from Huelva, in the •' Mediterranean, and brought 3950 toais of iron pyrites.
