credit for the work done, and the cards or books pass along to the wages office, where those who are on piecework rates are credited with the various amounts, and paid weekly, or the amounts are allowed to accumulate for a period settled between the shop stewards and the management, and the workpeople draw a weekly wage on time clocked, balancing the account at intervals.

In very large factories there may be a separate stores for tyres, another for brakework, frames and forks, and another for wheels, each floor or department having its own stores. Whether this arrangement or the one outlined is followed, the procedure is practically the same as regards the checking and recording of the work as it passes through the various processes.

Frame Building. We now enter the frame building shop, where the lugs and tubes are built up to make the frame. The lugs, in the form of castings or stampings, have been machined in the machine shop. This consists of placing the lug on a jig (a tool that holds the lug at the correct angle for turning, drilling or boring) which is bolted to the lathe or drilling machine which forms it. Iron castings are hollow and have little superfluous metal to be removed, stampings are solid and the steel to be machined away is considerable. Modern methods, however, allow either to be dealt with with practically equal rapidity, and when completely machined each lug weighs only a few ounces. Some firms, notably the Raleigh and Rudge-Whitworth, use pressed steel lugs, a process which presses the lug from sheet steel, which is folded, so to speak, between dies in a very powerful screw, or other type press. The frame builder is provided with a sort of master frame, called a jig, on which he assembles the lugs and tubes roughly, and when they are positioned by stops on the jig he
