 fairly familiar with the rules, and they
 are then put on a car with an old
 motorman. They remain on the car about a week or so, and are then
 brought back here for more advanced
 instruction and to tell what they have
 learned during their tour of duty on the
 car. If they are familiar with the
 ordinary usages they will be accepted
 and put through the more advanced
 course. There are many men who have
 absolutely no adaptability for the street
 car business, and we do not hesitate to
 tell them so.
 Now comes the technical part of the
 work. The candidate is first shown the
 inside of controller box and the man. ner in which it works. By system of
 lights show him just what happens
 every time he turns his controller. a point. There are eleven points on the
 controller and each one reresents a
 different speed and different manner in which the current affects the car and
 the motors. The candidate is first told there are two motors on the cars, and
 by means of chart is shown how the
 current enters the car either from over-
 head or underground. In the slot in the
 track, a section of which is shown to prospective motorman, he is told there are two rails, known as conductor rails. By means of slide attached to the car and called plough, the current is passed from one of these rails through a piece of metal called a shoe and affixed to the plough which slides along
 the rail. From the plough the current passes, by means of heavily insulated
 wires, through an overhead cut-out or switch. placed at one end of the car over the head of the man on the plat form. This is the box-like structure found attached to the hood of the plat form. From here the current is carried to the fuse box, and through a fuse of copper or composition metal-several different kinds being employed and their use explained-to the motor itself.
 Next come the pratical demonstra- tion with the controller. I should first have explained that there is a small box beneath the car, through which the cur rent passes before it reaches the motor. Through this the current can pass but slowly, thus preventing 1t being turned into the motors too suddenly and burn. ing them out. By a series of incidents this box for resistance, as it is called, can be burned out, and we teach the men how to avoid that.
 The candidate is then taught just what happens when he turns on the lever. He is shown that the first five points on the controller dial throw the current into the No. 1 motor first, and then to No. ? motor, and at the same time it is in the resistance box. On the sixth point the No. 2 motor is cut out and the full current goes into No. motor without any resistance. On the seventh point the current reenters No. motor, but this time it enters direct, without passing through the other machine, and, of course is stronger. There is still some resistance. The next four points cut out the resistance a point at 8 time until the last point, when there is no resistance at all, and the car is going at full speed.
 'The candidate is then shown several ways in which the controller box can be come disarranged or how motor can be thrown out of gear and how to remedy it at the controller box. He is then shown Row the current, after passing through the motors, passes through an- other overhead cut-out, or switch, like the first--at the other end of the car plough and through a shoe on the op- pesite side to that by which it entered, passes out to the other conductor rail, and on back to the power house.
 'The candidate is then placed on the car there, and is made to run it under various conditions. He is told that there are five things he must do if his ear becomes disabled. If in the daytime he must first try his lights, after having both levers from the con- troller box. Then he must go to the overhead cut-out and see that this is all right. This cut-out acts as an auto matio fuse, and when the current is put on too strong, or there Is a heavy load, It flies out, thus cutting off the current from the motors. This is remedied by simply pushing the lever which projects from the box back into the place again.
 If the motorman finds his cut-out is In place and everything is right there he proceeds to the fuse box and ex- amines the fuse. If this is all right he examines the connectioIl& on the plough. These connections are very simple, be- ing very much like the pins and catches you see in connecting the lights on the trailer from the front car There is pin on the car on which the heavy wire from the plough is fastened by simply pushing the socket on the plough wire over the pin. There are two of these wires, of course and the connections might be disturbed by jarring or other wise. This very seldom happens, how ever. If these connections are all right he motorman goes to his controller and ;ries his motors by cutting out one after he other. If none of these things is wrong the trouble is in his motor some- where, and is for the machine man at he shop to fix. The rnotorman then iecures his coupling pins and coupler tnd arranges his car to pick up the next ,ar behind to push him to the barn, as le is not supposed to know how to go urther in remedying the trouble.
