(b) There was unanimous agreement that corns at the 20-day stage yielded a 
better canned product than at any other stage studied. There appeared to be 
a combination of a number of independent characteristics which made the 
products at this stage most desirable. 
(c) The two varieties of field corn which were canned in the same manner as 
the sweet varieties were judged to be much inferior to the sweet sorts at com¬ 
parable stages. In view of the greater moisture content, the hardness and 
toughness of the kernels, the poorer flavor, and the difference in the nature of 
the polysaccharides, there would seem to be little possibility of making a satis¬ 
factory canned product from these by any modification of the usual methods. 
10. It appears that a first-quality canned product can be made from any sweet 
variety if the canning is done when the corn is at the proper stage of maturity.
