eries. ‘lhe can caser receives the labeled cans from the labeling 
machine, stacks them into layers, places the layers of cans into 
the case and automatically pushes off the filled case, while a 
new layer of cans is pushed forward. It is obvious that the 
mechanical can caser makes the work of packing the cans easier 
and accelerates its speed. ‘ 
Marking the Cases.—QOne end of each case is stenciled with 
the number of the batch; over the other end is pasted a case 
label, representing, enlarged, the brand of the label on the cans 
within. In the place of the case label, the respective brand may 
be printed on or burnt into the wood. ‘The burnt stenciling is

usually done by the manufacturer of the shooks. One side of 
each case is usually marked “Condensed Milk’ or ‘Evaporated 
Milk,” as the case may be; the other “Weep in cool, dry place.” 
If sweetened condensed milk 1s exposed*to excessive heat for a 
considerable length of time, as is often the case in storehouses 
rainst 
or in the hold of steamers, where the cases may be stowed a: 
the boiler room, it becomes brown, thickens rapidly and develops 
a stale flavor. Ivaporated milk also darkens when exposed to 
heat and depreciates in flavor. It should, therefore, be kept in 
a cool place. The humidity of the storage room has no effect on 
the condensed milk proper, the cans being hermetically sealed.
