MARINE REVIEW. 1§ Coal Movement to Lake Superior. As shown by the following table, coal shipments, hard and soft, to Lake Superior ports from the opening of navigation to Sept. 1, were 300,852 tons in excess of shipments on the corre- sponding date in 1891: 1892, 1891, Months. net tons. net tons.

Notwithstanding the Buffalo strike, which placed shippers of hard coal at a great disadvantage, and the restriction in the soft coal movement, on account of crowded docks at Duluth and Superior, the shipments during August are only a few thousand tons less than they were in August 1891. It is evident also that the greater portion of the gain in the movement to Lake Superior can still be credited to soft coal, as the shipments of hard coal out of Buffalo to all points on the lakes during August were only 247,562 tons, against 412,814 tons in July and 275,585 tons in August of last year. The en- tire movement of hard coal from Buffalo to all lake ports above Detroit was on Sept. 1 of this year 1,420,347 tons, against 1,- 392,003 tons on Sept. 1, 1891. St. Mary's Falls Canal Traffic in August. Freight passing through the St. Mary's Falls canal during the month of August was again greater in the aggregate than during August of any previous year in the history of the canal. The total was 1,772,731 net tons, of which 1,300,341 tons was eastbound and 472,390 tons westbound. The traffic was di- vided as follows: Eastbound. Westbound.

A New Injector for Marine Purposes. The machine, as the name implies, is a double tube one ; that is, it is provided with an independent lifting and forcing apparatus. By means of this independent lifting and forcing apparatus an injector has been produced that will work under a great range of steam pressure without any regulation of the water supply. For instance, the machine will start at from 15 to 20 pounds steam pressure with a short lift of say 4 feet, and without regulation of any kind will work at all steam pressures up to 225 pounds. 'This machine starts readily on a 1o-foot lift with 25 pounds, on a 15-foot lift with 30 pounds, and on a 20- foot lift with 35 pounds. Ona short lift with a steam pressure of from 30 to 150 pounds the injector will take feed water at a temperature of 145 degrees. 'The data given will show the great range of this injector. By referring to the sectional cut, while it may appear that the machine is complicated, it will be found upon a close examination that the parts may be easily taken out. The tnbes are all removable from the front end of the machine. 'The valve seats are all independent of the body cast- ing and can be removed, so that the valves can be ground to their seats, or if the seats become badly damaged they can be replaced by putting the injector in a lathe and turning the cas- ing up. -F. W. Wheeler & Co. of West Bay City, Mich. have adopted these machines as their standard. The American Steam Barge Company has also adopted them. A full set of these machines are on the steamer Gilbert, illustrated in this issue, and are giving perfect satisfaction. On the seaboard they have met with great success. 'The Newport News Ship-Building and Dry Dock Co. of Newport News, Va., the W. & A. Fletcher Co. and other large ship builders on the coast have adopted them as their standard. It is the only injector that will work successfully on high or low steam, whether on a short lift or a long lift. For prices inquire of the Hayden & Derby Manufacturing Co., 111 Liberty street, New York. United States Commerce Through the Welland.
