Fig. 4 shows the dies and plungers for making tlie back sec-tion of a locomotive side rod. We have several of these siderods in service, and some of them have come to the blacksmithshop to be straightened after having been badly twisted up in awreck: they showed no fracture, proving that they were wellmade. Fig. 5 illustrates the dies and used for formingthe forked end of a main rod. George W. Kelly (C. R. R. of N. J., Elizabethport, N. J.) :—We have a 5-in. universal Ajax machine, driven through gearsby a 40 h. p. motor, and a iA-in. machine equipped with theautomatic contml made Iiy the Monitor Controller luachine is started Iiy simply pushing a button attached.

This energizes a series ofrelays in the controller box on the wall, which are so adjustedthat the current fed to the motor will not overload the circuitand damage the motor. The system is so regulated that themachine will ordinarily attain full speed in about six secondsfrom the time the button is pushed. It is stopped by pushinganother button. This system saves time for the operator, asthere are no belts to shift, no switches to pull, and no rheostatto fool with. There is a saving of electricity, as the machine,will more likely be stopped when not working; a saving in thelife of the motor and perhaps in the wrecking of the machine may be inched along as readily as before andthe system on the whole has proved satisfactory.
