74 with this little case during the past year or so. One case which was thrown overboard from the steamer - C. H. Starke on Lake Michigan was discovered nine days later. A mes- sage from the steamer Western States was floated on Lake Erie on Oct. 27, 1909, and found on Nov. 13, 1909. A message from the City of Mackinac thrown off near Point Au Barques, Lake Huron, on Oct. 26, 1909, was picked up six days later about sixty miles east northeast from the point where it was cast adrift. One mes- sage from the steamer C. W. Kotcher was found 167 days after it had been cast adrift, having been thrown upon Outer Duck island, which is uninhab- ited during the winter. The case is cylindrical in form with handles, at either end so that it may readily be grasped by a boat hook. The handles together with the casings and cap, are burnished to catch the sunlight. The cork lining makes the case unsinkable even if it should accidently become filled with water. It would seem as though there ought to be a place aboard every vessel for the simple little device.. Sulphur Dioxide Fumigator The Fumigating & Fire Extinguish- ing Co. of America, 29 Broadway, New York, has acquired the United States patents granted to Paul H. Grimm for apparatus to manufacture sulphur dioxide and is prepared to furnish plans and estimates for the work and to complete equipment of vessels. The company has built and equipped a barge with two furnaces of the largest size yet made with ample power and blower sets for operation anywhere in water adjacent to New York for the fumigation of ships. for vermin as well as the prompt ex- tinguishing of fire on board without damage to cargo. The apparatus consists of two parts, namely a furnace (which may be lo- cated in a deck house) for making the gas from sulphur under pressure, and an air compressing plant consist- ing of an air pump and a tank for storing the air which may be located in any convenient location, but pref- erably the engine room. The air is carried from the tank through a pipe to the sulphur-burning furnace, the tank being kept. charged with air continually so that all which needs to be done at the furnace is to light the fire and turn on the air after the discharge pipe from the furnace has been connected to the compart- ment on fire. As soon as gas is generated from the burning sulphur THE MARINE REVIEW it is driven by its own elastic force from the furnace to any desired point. The mechanical advantage of pump- ing air as against pumping gas is ob- vious. An apparatus for pumping air can be kept in very, good condition at small cost, whereas the apparatus for pumping gas is short lived. Marine Glue L. W. Ferdinand & Co., 201 South street, Boston, Mass., are the manu- facturers of a marine glue which has met with much success aboard ship. This glue is extremely flexible, allow- ing the timbers to contract and ex- pand and at the same time retain its wonderful adhesive powers. It does not stick to the feet in hot weather. It should be used at a heat of from 250 to 300 degrees Fahr., at which temperature it is perfectly liquid. About 14 lb. of Jeffery's ex- tra quality marine yacht glue will run from 200 to 250 ft. of seam 3%-in. deep by %-in. wide. If properly used it will last from four to six years in a seam and has been known to last from 10 to 12 years. When care- fully applied to a dry deck it will never leave the sides of the seam. The manufacturers will send full di- rections for using this glue to any- one interested. Automatic Storm Oil Device The use of oil to still troubled wa- ters has been known since _ biblical times, but notwithstanding its dem- onstrated efficacy it is but little prac- ticed. During the past few. years, however, the Hydrographic office has brought it pertinently to the atten- tion of American mariners and it is coming into more general use. On the lakes it is generally permitted to drip from bags suspended from the bow of the vessel. Loveridge Ltd., Cardiff, Wales, are now marketing an automatic wave subduer. It is a compact little ma- chine of cylindrical form intended to be installed in the forepeak of a ship with two small pipes leading for- ward and passing through the bow plate on each side of the stem. Each pipe has its own tap, so that the flow can 'be regulated according to the direction of the wind and sea. A heavy piston working in the cylinder attached to a tubular rod and acting by a spring in addition to its own weight, ejects the oil onto the wa- ter. The reservoir and cylinder to- gether hold about twelve gallons and the discharge is about one-third of a gallon per hour, according to density. tional Tube "with 'available floor space is February, 1912 A great many testimonials have been received as to the reliability of the device. N. T.C. Regrinding Valves -- Bulletin No. 7, issued by the Na- Co., Pittsburgh, deals regrinding valves which are made by this company. The bulletin says that the question as to how long an N. T. C. regrinding valve will last has recently been answered. The, N. T. C. regrinding valve is made at the same works as the "Ke- wanee" union, which is tested to 125 lb. compressed air under wa- ter. The test of Kewanee unions is conducted on a special =ma- chine whose construction necessitates the use of a valve. The valve was opened and closed every time a Ke- wanee union was tested. One of the testing machines was selected as the medium to answer the question how long will an N. T. C. regrinding valve last in continuous _ serivice.. Several %4-in. N. T. C. regrinding valves were taken from _ stock, no effort being made to select the valves, and placed on the air lines of four testing machines. One of the N. T. C. regrinding valves was opened and closed 327,094 times be- fore it began to leak. It was then reground and again put on the line, At the present time this valve is still working satisfactorily under 125 Ib. air pressure. The regrinding of the N. T. C. regrinding valve is one of the most prominent features of its construction. The ease and speed with which it can be reground commends it to all engineers. The Pittsburgh branch of the H. W. Johns-Manville Co. now occupies the entire eight-story stone, reinforced con- crete and steel building at the northeast corner of Wood and First avenues. The building which is one of the most substantial structures in the downtown section of Pittsburgh, has been leased by the company for a term of years. This building is 31 x 96 ft, and the approximately 23,808 sq. ft. The Streckfus Steamboat Line, St. Louis, Mo., operates the steamer Quincy between St. Louis and New Orleans. The Quincy is a wooden sidewheel steamer 265 ft. long, 42 ft. beam and 7 ft. deep. Her engine is 23 in. cylinder diameter by 8 ft. stroke, supplied from four Scotch boilers, 44 in. diameter and 26 ft. long, allowed 175 lbs. steam pressure. She has sleeping quarters for. 300 passengers and is quite popular on the. route.
