TRIAL TRIP OP THE NARVAL SOME WONDERFUL THINGS ACCOMPLISHED BY FRANCE'S NEW SUBMARINE TORPEDO BOAT. Paris, June 20. Conflicting reports have appeared in regard to the recent severe trial to which the French torpedo boat Narval has been subjected, but the opinion in naval circles is that this vessel, which is the latest type of her class, and which has been selected as the model for four torpedo boats now under construction, has proved successful. There are two distinct types of submarine vessels in the French navy. The Gymnbte, the Gustave ZCd6, the Morse and twenty-six other submarine boats 11 build depend exclusively upon electricity for their motive power, and this greatly restricts their radius of action.

On the other hand, the Narval, which is considered by the French experts "the most perfect type of submarine vessel yet constructed," i supplied with both steam and electric motors, which enable her to attain a radius of action of miles. The Narval is propelled by steam when navigating on the surface, and by an electric motor with accumulators when navigating under water. The great advantage of this double system is that with her steam power she can re- charge her electric accumulators, which, to borrow the French expression, makes her "autonomous." Steam is generated by the Seigle tubular boiler. The fuel is petroleum The Narva! is 112 feet long, and her displacement is lit) tons when on the surface, and 200 tons when submerged. She is provided with four torpedo tubes, capable of discharging four torpedoes feet in length.

Last autumn the Narval was tested satisfactorily for submersion and submarine Steering, and the trial to which she was subjected on May 22 was to ascertain her capacity for endurance or "autonomy." The Minister of Marine ordered the Narval to make a cruise of forty consecutive hours. She left Cherbourg at 1 o'clock in the afternoon of May 22 in a very heavy sea, caused by a northeasterly gale. The torpedo destroy Zouave accompanied her. The orders we to return to Cherbourg on Saturday morning. May 21.

Under stress of bad weather she put Into St. Ifalo at o'clock on Saturday morning, and, owing to an accident her pumps on the return voyage from St. Ifalo to Cherbourg. klp- was towed for thirty miles daring three boars by the Zouave. This was the Bole departure from the programme.

The Narval covered 350 miles at an average speed of six and one-half knots ii hour in a very rough sea. On the trip she remained below the surface for several hours at a urn-, and twice recharged her accumulators. On May St. Maio without taking in fre3fa provisi-nis or fuel, and on arrival Cherbourg she excellent practice with her four torpedoes, thereby showing that the torpedo mechanism, regulated five days previously, had not been put out of order the trial.

and crew of the Naival suffered greatly from the discomforts of the trial trip, and that before fresh trials are undertaken this must be remedied. On the whole, the endurance trial of the Narva) is considered very satisfactory, and, according to French experts, proves the Narval to be much more formidable than the submarine vessels of the Holland type. According to the French official reports the Holland's best endurance test was made in fine weather, and lasted forty-eight hours, during which the vessel accomplished 145 miles at a speed of live SINKING A CAISSON FOR THE FOUNDATION OF THE NEW STOCK KXCHYXCiE. site the old building, in Broad-st. and six-tentha knots.

The French reports also say that tin- Holland during her endurance dial trip navigated only the surface, without making any dives, and not discharge any torpedoes.
