All of the illustrationsare new and striking, the application ofthermit seeming to run with mercurialswiftness into many unexpected situations,such as the welding of new teeth intolarge gears, driving wheel spokes, con-necting rods, mud rings and this work it may be noted that there areapproximately 345 railroad shops in NorthAmerica where welding processes are suc-cessfully carried on. The new calendar isunique in design, elegant in presentationof facts, and very interesting.

A forming die, a cutter, or whatever isneeded to give the bar its initial cut orshape is rigidly attached to the movingcrossbeam, the face of which is shown inthe cut. (The four vertical T slots inthe moving crossbeam furnish amplemeans for attaching dies.) A formingor holding die is also placed against thefixed cross beam to guide or shape theoperation. Where many pieces of thesarre size must be formed, the die is notremoved until all pieces are ready for an-other operation if needed. A notable feature of this machine isthe arrangement of its three rams, allconnected to the one head to permit theuse of only one, of two. or of all threerams, depending on the pressure one ram—the middle one—the capac-ity of the bulldozer is 56 tons; with thetwo outside rams, 127 ton
