The Dobbie- McInnes system of deep sea sounding in- troduces a highly perfect- ed means of obtaining accurate soundings at any normal depth or speed. It dispenses with the use of glass tubes with their ob- vious disadvantages and employs an improved me- chanical depth gage with-- out springs or other de- rangeable parts. The working of the instru- . ment is based on the pressure of the water, the depth gage having a very small hole through which the water is forced against the air pressure as the lead is lowered. On being brought to the surface the depth gage is it measured by a _ small ebony gage. As. the working of the instru- , ment depends entirely {- upon the pressure of the water soundings up to 100 fathoms can easily be taken while the vessel is going full speed. By means of an outrigger the machine can easily. be operated from the bridge. chine has met with favor everywhere. In fact, it recommends itself to any practical man. The machine is manu- factured by Dobbie-McInnes, 57 Both- well street, Glasgow, Scotland. ~ An Unusual Boiler House Built as part of Boston's new $9,000,- 000 port development, the boiler house on the Commonwealth fish pier has some unusual features, consisting as it does of three distinct structures with- in the four walls. For various rea- sons, including a delay in the deliv- ery of structural steel, the reinforced concrete walls of this building. were put up and completed by the Aber- thaw Construction Co., Boston, before the steel was on the ground. The structural members have been erected inside the walls,.to carry floors and the huge coal pocket, and are inde- pendent completely of the walls them- selves. The third structure, which again is of reinforced concrete, is the big chimney 'located in the building near one corner and projecting far above the roof. 'hes ma: THE MARINE REVIEW The outside dimensions of the con- crete structure are 56 ft. 6 in. by 70 ft., with a height above ground floor of 79 ft. This structure is virtually DEKE SEA -SOUNDING "MACHINE an enormous concrete box without in- ternal bracing of any sort. It is not tied together by the structural mem- ° bers, as would have been the case un- der ordinary conditions of erection. It is constructed wholly of concrete with steel reinforcing bars, there being no structural steel members embedded in the concrete, either for wall columns or wall beams. All of these are of reinforced concrete only, giving the outside of the building something of a lattice work effect on a huge scale-- an effect which is enhanced by the al- most total absence of windows and ether. openings. Charles L. Rohde & Sons Co., Balti- more, Md., are building a two-track Darec. 230 it; 'long, 34 ft: wide and 8 ft. 6 in. deep, capable of carrying ten cars, and also four covered light- ers, 80 ft.. long, 24 ft. wide and 7% ft. deep.

The steamship El Mundo, of the Southern Pacific Co.'s fleet, is being transformed from a coal burner to an oil burner at the yard of the Newport News Ship Building & Dry Dock Co., Newport News, Va. A number of the ships of the Southern Pacific Co. have been similarly transformed at the Newport News ship yard during the past two years. -This transfor- mation involved a very considerable amount of work on the structural hull in making provision for oil bunk- ers. The steamer Newport News, of the Norfolk: & Washington Steamboat Co.'s fleet, is in dry dock. No. 1 for repairs to rudder and to damaged joiner' work. The Southland and Northland, belonging to the same com- pany, will follow the Newport News at the ship yard for their annual spring overhauling. The prompt rescue of a man who fell overboard from the steamer Peru, of the Campagnie Severale' Trans- Atlantique, is attributed by the offi- cers of the company to the prompt | launching and releasing of the life- boat through the use of the Raymond automatic releasing hook, and _ the same was also true of the rescue of the crew of the brig Bertha-Marie in mid-ocean, Jan. 23, 1914.
