FROM FACTORY TO CONSUMER 
Cuarter XVI. 
Stamping.—Fvery well regulated condensing factory, selling 
condensed milk in hermetically sealed tin cans, employs some 
system of marking the cans. This is important for future 
reference. 
When defective condensed milk is returned to the factory, 
the marks on the cans tell the manufacturer the date of manu- 
facture, and his own record on file in the factory shows the con- 
ditions under which the defective milk was made. In this way 
defects can usually be traced to their causes and the recurrence 
of similar trouble can be avoided. 
In some factories the batches of condensed milk are num- 
bered from one up, and the cans are stamped with the respective 
batch number. ‘This method is simple but may prove undesirable, 
since 1t informs the competitors also of the date of manufacture 
of competing brands. In most factories a code of letters and 
figures is used, designating the factory, the date, and the number 
of the bateh of each day.
