164 house is forward and the quarters for the crew, galley. and dining room are in the after house which is built flush with the side and end' of the hull. The machinery will consist of a 16,-34- by 26 fore and aft compound engine with jet condenser, and a Scotch Holler 11 ft. 6 in. by' 13 "ft; 150 'ID: pressure. The vessel will be lighted by electricity, including arcs for load- ing and unloading. The sand pumps, of which there are two, are the Mor- ris 12 in. pumps built especially for sand-sucking purposes. They 'are placed on the after end inside the deck house and the-hose is handled by a derrick erected, in the roof of the house. All the work done in con- nection with the pumping is handled in the roof of the deck house, which is kept as clear of obstructions as possible. DEEP SEA SOUNDING MACHINE. The deep sea sounding machine de- scribed in the February issue of THE Marine Review and which is being in- stalled on a great number of lake freighters, is the invention of Dobbie, McInnes, Ltd. 57. Bothwell street, Glasgow. This instrument has met with a most favorable reception on the lakes, and it is probable that all of the modern freighters will event- ually be equipped with it. SCHUETTE RECORDING COM- | PASS. The Schuette Recording Compass Co.,: Manitowoc, Wis., has had excellent re- -- sults with its recording compasses which have been in daiily use on the great: lakes the past year and a half. These - instruments are the only ones in use on the lakes, if not in the entire world, and the company intend to place quite a number of them on ships this spring. The instrument which is specially de- signed for use on ship board and is so constructed as to produce a continuous record of the direction of a ship with relation to time; so that the direction in, which the ship was moving at any hour and minute can-be determined at a glance at iany time thereafter from an inspection of the records produced. The instrument shows -variations of about 214° (or a trifle less than a quar- ter of a point) so that if a ship is on her course and the wheelman lets her. go off 214°, the instrument will immedi- ately register the change of direction, and aiso the exact time this. occurred, so that a captain, by looking over his chart, can tell whether his ship had - been working to starboard or to port, and whether his instructions had been The MarRINE REVIEW followed. The chart. will also show the conditions of the weather, as 1m a seaway the records will be very irregular, while*in smooth water a. comparatively straight line will be produced. ; The size of the instrument is 2 ft. square by 10 in. deep and it can be connected to any ordinary socket, any place on the ship, and "any . Cuts rent can be used from 90 to 120 voles; it requires no attention except plac- ing a new chart on the roll every month, and filling the pen about every two weeks. The clock movement which moves the chart exactly two and one half inches an hour is wound electrically and requires no attention whatever. One of the special features is the circuit changer, which automatically throws the instrument on a set of batteries if the dynamo current for any reason should give out, and again throws the instrument on the dynamo curcuit when the dynamo is again in operation, so that the appa- ratus is constantly in commission. The chart will last thirty-one days and the time and date is printed thereon, The time is. gtadwated to «five minute spaces, so that it is an easy matter to ascertain the time to less than' a: minute: ata; elaneess< All points east of north and south are shaded, while all points west of north and south are clear; so the chart can be read with comparative ease. : The binnacle, which goes with the instrument, has all the necessary appliances for affecting perfect com- pensation or adjustment for. heel, quadrantal and. semi-circular devia- tions. The company will mail an actual chart taken on ship board upon ap- plication to anyone interested. A NEW ENGINE BUILDING CON. CERN. "The: Admiralty Power Company" is the name of a new concern which has actively taken up the building of ma- tine gas power plants at Port Rich- mond, Staten Teland) Ni; Y. Geo; H. Betts is president of the concern, C. Lee Straup, vice president, and Jas. H. Davidson, secretary and treasurer. The firm is composed of members of the Staten Island Ship Building Co. and C. Lee Straub, who was formerly vice president of the Marine Producer Gas Power Co.,.of New York. The Staten Island Co. has been long prominent in the building of tow boats April, 191 7 and lighters and has taken an active interest in the building of marine gas and oil power plants. Mr. Straub js well known in the gas power field and has devoted much time to the devel. opment of the marine gas producer. The company has now under copn- struction a 4-cylinder, reversing single- acting engine of 250 i. hh. p. at 200 r. p. m., for a small lighter and an- nounce that they are at present equip- ped to build gas power units up to 1,000 horsepower, and _ have ample capital to develop the business. It is recognized on all hands that marine gas power is bound to come, and ag- gressive action, such as the new con- cern may be expected to take, will hasten its development. TONAWANDA AS AN INDUS. ' TRIAL SITE. The Federal Rolling Mill Co., of Lockport, N. Y., have purchased river frontage at North Tonawanda and will erect elevators and a mill upon it. The North Tonawanda board of trade, through its president, William M. Mills, have advanced a most perti- nent argument to show the advantage of Tonawanda over. Minneapolis and Duluth as a miil site. To begin with, the freight rate on a barrel of flour from the head of the lakes to Buffalo is 30 cents. It takes four bushels of grain to make a barrel of flour. Fig- uring the freight on grain at 2 cents per bushel from the head of the lake , to Buffalo, which is a. fair average, it is apparent that there is a saving of 22 cents per barrel, to say nothing of the by-products which, of course, are free. The saving in 'the freight in the flour alone would be $220 per day on a 1,000-barrel mill, plus the freight on the by-products. Moreover, Tona- wanda is located in the heart of the vast consuming population reached by the best shipping facilities. THE COPPER HANDBOOK, VOL. IX. The ninth annual edition of the 'Copper Handbook, edited and_ pub- lished by Horace J. Stevens, Hough- ton, Mich. is just received. This work, which has become a_ standard authority on the subject, for the en- tire globe, has, in its latest edition, 1,628 octavo pages, containing consid- erably more than a _ million words, and, in addition to the miscellaneous chapters, lists and describes no less than 7,751 copper mines and copper mining companies, in all parts of the world, descriptions ranging from two or three lines in the case of compan-
