TANK STRAINER, In the design of tank strainer shown in the illustration, theconnection to the tender is from the left and a copper screenis set at such an angle and location that the flow will force anysolid particles larger than the perforations off from the .^creenand into the receptacle below. At the same time the screen ispractically vertical across the flow of the water and thus offersthe least obstruction. It is accessible for cleaning by the re-moval of a single nut, which releases the head having a grout:d. Tender End r-H^-J J-. ^ Tic\.

The removal of a plug at thebottom not only permits the flushing of the strainer but alsodrains all connections between the tank valve and the strainer is very simple in its arrangement and construc-tion and was designed in the mechanical engineers office of theIllinois Central Railroad, where it is being put into very ex-tensive use. New Electric I^xcmotivls.—The Traction System isbuilding six heavy electric locomotives at its shops in Decatur,111. They will be equipped with four General Electric, with Sprague-General Electric, multiple unit type Mcontrol. The trucks will be furnished by the American Locomo-tive Company and the air-brakes will be Westinghouse EL. Thelocomotives will resemble in general outline the steel turtle-back cars in use on this line, and will be 34 ft. long, 9 ft. 3,
