22 MARINE REVIEW. [April 19, HOLLOW STAYBOLTS, : Officials of the Falls Hollow Staybolt Co., Cuyahoga Falls, O., say that the increase in the use of hollow staybolts among ship builders has been so large of late that it is only a matter of a short time until this kind of bolt will be used almost exclusively in marine prac- tice. Builders of locomotives were ahead of the ship builders in adapting hollow staybolt iron and in that line also there is a very large increase in the amount of it that is being used. It is specified by the railway companies. Rules of the United States steamboat inspection service require that where solid bolts are used they must be drilled at the ends, so that breaking bolts may be de- tected. It was this safeguard for the detection of broken bolts that led to the development of the hollow bolt by the Falls company. They make both solid and hollow bolts but they claim that the latter are better than drilled or punched bolts in every way. The hole is central and-of any size desired, extending clear through the entire length of the bolt, making the strength uniform. The end next to the fire-box may be closed or left open. The best quality of charcoal iron is used. The drilling of tell-tale holes in the ends of solid bolts cer- tainly weakens them and causes them to break at the vital point, while it is claimed that the hollow bolt is even stronger than the solid material and is a self-inspector, a detective. It is more flexible than a solid or VALUE OF STOCKS-LEADING IRON AND STEEL INDUSTRIALS. Quotations furnished by HERBERT WRIGHT & Co., Cleveland, date of April 18. 1900. NAME OF STOCK.

From the far north among ice fields, in a part of the world almost desolate of civilization, with nothing but snow and cold _of the severest kind, comes a letter to the Chicago Pneumatic Tool Co. congratulating them upon work accomplished with their new submarine drill. The writer, Mr. Beliankian, is a constructor in the Russian navy, who is in charge of a gang of men working on the damaged battleship Apraxin. He writes very flatteringly in the Russian language of the hard tests to which the drill has been subjected under water in drilling through granite and other substances. A photograph of his surroundings shows the most undesirable place imaginable. 'Excuse me for writing in Russian," he says. "My secretary is in St. Petersburg and I am here alone, with noth- ing but snow and ice, and the mail reaches me very seldom, as the sea is frozen all around." Andrew D. Cramp, who was at one time the superintendent of the Cramp ship yards, died in Bioston a few days ago. He was forty-three years of age. After leaving the high school he began as an apprentice in the yards and progressed rapidly. He was a son of William Cramp. He had been ill for a number of years.
