fresh milk, or unsanitary condition of milk cans, vats, pipes and 

 conveyors in the factory, or unclean tin cans. Fat separation and 

 curdiness of evaporated milk suggest a faulty process. Fermenta-

Systematic Examination a Necessary Feature of Economic 

 Manufacture. — Manufacturers who neglect to conduct a systematic 

 examination of their product, similar to that outlined above, fre- 

 quently argue that they cannot afford to' waste five cans out of 

 every batch. 



This is indeed a mistaken conception of economy. With the 

 exception of fermented milk, the "cut-opens" can be emptied into 

 the succeeding batch, so that all that is lost is the tin cans. Fer- 

 mented goods cannot be utilized anyway, neither on the market, nor 

 elsewhere. Their loss, therefore, will occur whether in the form 

 of "cut-opens," or cans intended for the trade. 



The slight waste incurred by cutting open cans with sound 

 contents is insignificant as compared with the incalculable savings 

 which this practice may make possible, by the early detection of 

 faulty goods and the prevention of their recurrence, by enabling 

 the manufacturer to withdraw suspicious goods from the market 

 before they have ruined the reputation of the respective brands, and 

 by furnishing a reliable check on the work of the employees, whose 

 knowledge, that their product is subjected to, and must pass a rigid 

 examination, acts as a moral stimulus for high quality, skill and 

 carefulness.
