DRYING THE CEREAL. 
After the cereal has been sterilized it may contain too much 
moisture to be packed, and a drying process then becomes necessary. 
In the case of cereals which are not flaky and to which agitation is 
not injurious, a sterile chute with baffles (fig. 6), through which hot,

dry air is blown, would be effective. The air is thus placed in contact 
with the falling cereal. In the case of flaky cereals a belt elevator is 
necessary, but this can be inclosed and the hot air used as in the 
former case. Both elevators should be so constructed that they can 
be readily sterilized # with air at a temperature above 1S0° F. This 
should be occasionally done as precaution against infestation. 
THE SEALED CARTON. 
The sealed carton may be made of a stiff, though perhaps a cheaper, 
grade of cardboard than is used when the cardboard itself is printed. 
The printed label 
should be made in 
three pieces, 
namely, two ends, 
which lap over the 
edges and extend 
a short distance 
down the side ; and 
a side piece, which 
securely covers 
the edges of the 
end pieces. (See 
fig. 7.) One sealed carton was observed which had a strip of paper 
pasted across the comers before the ends were put on. This further 
insures the resistance of the carton to insect attack and is advisable. 
provided the cost is not too great. 
A sealed package was observed on which the ends of the carton 
were not as firmly glued as they would have been had the package
