SUFFERINGS AT SEA.

Particulars have been received at Liverpool ■with respect to the wreck of the barque Ysusquiza. She left Baltimore for JTewry, Ireland, oa February 13, -with a cargo of grain, and manned by a crow of 12 hands, all told. At midnight on the 20th, the wind blew with hurricane force, accompanied by very heavy ksz, which threw the vessel on her beam-ends and caused the cargo to shift. The seas broke over her continually, smashing the longboat, and doing considerable damage. Two of the deck planks were torn up, and the water rushed into the hold in'large quantities. The foremist was cut awaj; to right her, and a spar put GTflr the side, which somewhat eased her. On the following day there wag no abatement in the wind, and the seas again made clean breaches over the vessel, carrying away every movable thing. The crew kept at the pumps until tho 22nd, but were unable to free her, and on that date tho stern of the vessel commenced to break up. The pumps became choked, and the crew in tho evening abandoned their vessel. With the greatest difficulty two of the boats were cleared and launched, the larger one containing the captain and six of the crew, and the smaller one, tinder the command of the mnte, having Ave occupants. So dangerous was the sea that bundles of clothes and bread-bags attached to lines were put over the stem in order to make the boats ride head on to the sea. The, weather moderated slightly, and the two boats kept by the wreck until the night of the 23rd, intending to board the vessel on the following day to get a fresh supply of provision! and water. A gale of great violence, however, sprang up during the night, and* the captain orderod all the clothes, prorigions, and water, in the larger boat to be thrown overboard to prevent the boat itself being swamped. Aa the morning of the 24th dawned nothing could be seen of the small boat, containing the mate and four of the seamen, and it was ooncluded that all had perished. The 25th waa a day of intense suffering—the ■urvivors not having the slightest quantity of bread or freßh water to satisfy their extreme hunger and thirst, and they all gave up hope of witnessing- the appearance 5f the morning. During the night the weather

became somewhat calmer, and, as the morning broke, a barque was descried on the horizon, and she bore down'to their assistance. She proved to be the Italian vessel Armonia, and sue rescued the seven survivors, but not before the Ynusquiza had almost sunk. The shipwrecked men were on board the Armenia several days, and were landed at New York. —Times*

A DIFFERENTIAL COUNTER FOR STEAMSHIPS. j There has recently been introduced on board ' the vessels of the French naval squadron in the , Mediterranean a differential counter, designed ! by Captain Valessie, to regulate the rate of i speed of steamships. It has been highly appreI ciated by the commanders. By means of it the ship can bo kept, much better than previously, at the speed assigned to it among the other ships of the squadron, and, by simple observation of the instrument, an indication is had of the means of regaining the proper po3t, by advancing or falling back, when the vessel may have lost that post through momentary defioit or exi cess in the engine's velocity. The apparatus I consists, firstly, of a watch or timekeeper, the ' hand of which, beating seconds, makes the circuit of the face in one minute. This watch is fixed on a rota.ting-boss, which is centred with the same axis as the hand, and to which the engine of the ship imparts a movoment of rotation in an opposite direction to that of the hand. By means of gearing for variablo multiplication of the speed, the engineer establishes for each rate of going of the engine such a relation between the number of turnt of this engine and that of the boss which carries the watch, that this lattor makes precisely one turn per minute for the desired speed-rate of the engine. The hand of the watch then remains motionless opposite a fixed mark on tho case of the instrument so ong as the engine is kept at the speed commanded. If the speed gets quicker, the hand goes back from the fixed mark ; if slower, forward. The arrangement thus gives a very sensitive indication, enabling the engineer to keep the engine at the rate commanded. Further, if tho hand be a few seconds behind or before, it indicates the number of turns made in excess or deficit, and the attendant has merely to accelerate or retard the pace till the hand comes opposite its mark, in order to bring tho ship to its proper post again. This imvention has recently received the Plumey prize in the French Academy.—Times. REMOYAL OF WRECKS BY TORPEDOES. The Bordeaux newspaper La G-ironde reports that Messrs. Xewton Brothers, of Hull, have been employed to remove, by means of their torpedoes, the sunken wreck of the steamer Louisiane, which since December, 1875, has interfered with the navigation of the river Gironde. So serious was this obstruction that the French Government decided last January to apportion 80,000f. for the speedy removal of the wreck, and ultimately entered into an engagement with the English firm above mentioned, who despatched from Hull to Bordeaux their salvage sloop Rising Sun, with a crew of divers and torpedofixers, her cargo, consisting of charged torpedoes, being admitted into France free of duty. On the 17th instant a large party comprising Government officials, the Prefect of the Gironde, the Mayor of Bordeaux, and a party of ladies and gentlemen, assembled on board the steamer Patriote and witnessed several explosions, which were conducted under the superintendence of Mr. Cr. B. Newton. The effects of a 651b. torpedo were very remarkable. The Louisiane appeared to be forced out of the water and shattered in all directions.
