Win rever it has been found to beadvisable to do so, special machines have been designed to doduplicate work in quantities, and in our next issue we willillustrate a checking machine that has been built in the shopsto do the checking or gaining on the belt rails. An examina-tion of the drawing will show that these belt rails have awidth of 2J in., and that the body braces have a width of 2 is therefore necessary that the belt rails should be checked.

Also that the raising ofthe body is not done by simply screwing up the rods, but theyarc first relieved of all strain by jacking. By the use of thecontinuous rod, also, the expense of the turnbuckle is saved,and the danger of its slackening olT and thus becoming looseobviated. The only objection that, can be raised to this con-struction is that if a rod breaks, it is more difficult to put in anew one where there is no turnbuckle than where one is used :but, on the other hand, the breaking of truss-rods is such ararity that tin- saving effected in lite- other direction is a prac-tical insurance on this our possible source of loss. As all parts of the car have been reduced to standard sizes,the work hi construction is greatly simplified ami new cars are being built or not, the various parts or gained to a depth of 2 in. t
