IV SELECTING GIRLS AS ASSEMBLERS Quantity production, as it is being carried on to-day, May be roughly divided into three parts: first, manufac ture, which consists of the actual work, machine or hand w ork, required to bring certain materials to the desired dimensions; secondly, inspection, which consists of the w atch which is kept upon each part in the process of man ufacture in order to detect any flaws which might occur; thirdly, assembling, which consists of putting together the Manufactured parts into the finished product, the final goal of the productive process. In times past, these three Phases were combined, for the craftsman was manufac turer, inspector, and assembler all in one. However, the division of labor has separated the productive process into these general functions. And it is probably safe to sa y that no matter how far this division is carried and how tefined the methods of manufacturing become, these three general functions will remain. There will always be neces- Sar y a large class of machine operators and bench hands, shaping the actual materials. There must always be in spectors to inspect the work done both by machines and h Y hand at every step of the manufacturing process. And there will always be assemblers who put together the com peted parts and who make those slight adjustments Much are necessary at the end of every fabricating proc- ess no matter how perfect it may be. In conducting these experiments, it was inevitable S3
