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
