 shelves are about 15 feet in height. 



After the starch is thoroughly dried, it is placed in

 method of drying that some parts of the starch come from 

 the kilns drier than others, as this banking or heaping of 

 the starch is very essential in order to get uniformity of 

 moisture. After the mass of starch has become uniform 

 in its content of moisture, it is placed in barrels and is 

 then ready for transportation.

Starch and its by-products have many uses in the

 print works. The makers of prints are even willing to

 Indian corn. 



In the textile industries, it has come to be used exten-

It is used in the manufacture of cotton, woolen, linen

 for the warp yarn before it is woven ; for finishing goods 

 after they have been woven ; in the form of dextrin or
