 work from being done. Good inspection will aid 

 production in every way possible to run down the 

 causes of bad work, to remedy these causes, and 

 to preclude the repetition of the trouble. When 

 an occasional bad piece comes through, it may be 

 sufficient simply to throw it out; but, if the trouble 

 becomes chronic, a prompt effort should be made 

 to locate the cause. If it lies with the workman, 

 the matter should be taken up with him at once. 

 He should be instructed in correct methods until 

 he can do the work right; then, if he cannot learn, 

 he should be transferred to work which he can 

 do, or should be let go. But the blame should 

 not be put on the workman before the cause of 

 defective work is ascertained. It may lie with 

 the tools and their setting, or with the machine, 

 or with the workman's instructions. It is some- 

 times desirable to have a systematic record of 

 spoiled work as a line on the capacity of the vari- 

 ous workmen, and as a guide in the methods of 

 manufacture. 



Standards of Inspection Will Vary. Standards 

 of inspection involve matters of general policy, 

 such as the demands of the market and the kind of 

 competition to be met, as well as the methods of 

 manufacture and the type of tools which will be 

 used. In a machine shop, for example, the degree 

 of refinement required will determine whether a 

 piece is to be made on a lathe or on a precision 

 grinder, whether a gear will be cast or generated, 

 hardened, and ground. It is obvious that the
