MISSOURI AGRICULTURAL REPORT. 



TABLE A. 



This table tells of the total proteid matter ; a very little is in the tip 

 caps, little in the hull, about six-tenths in the horncy part, about one- 

 sixth in the white starchy part and about one-fifth in the germs. Of 

 the total oil, the horny part, contains less than one-seventh and most of 

 the rest is in the germ. The germ likewise contains about three-fourths 

 of all the mineral matter which forms part of the compounds contained 

 in the seed. The last column shows that the white part shown in the 

 drawing, while called the starchy part, in reality contains less than one- 

 half the amount of starch and starch-like compounds which are in the 

 kernel. The horny part, which is richest in proteid, is also richest in 

 starchy matter. 



To cause nature to increase the amount of proteid matter is one of 

 the most important of the modern problems for the expert corn grower ; 

 for if he can so change the conditions of feeding and growth that the 

 proteid matter will be increased and the starchy matter decreased, his 

 grain of corn will more quickly approach the balance ration and will 

 contain more of that substance for which the farmer pays most when he 

 buys concentrated food stufiis, for concentrated food stuffs are food stuffs 

 rich in proteid matter principally. 



Dr. Hopkins of the Illinois Agricultural Experiment Station has 

 had wonderful success in coaxing Dame Nature to make more concen- 

 trated food stuff's in the laboratories which are situated in the corn. He 

 has been able to increase the proteid by more than one-third and this is 

 accompanied by a large increase in oil and the consequent decrease in 

 starch. 



Even if one should want to raise corn for the starch factory, it 

 would probably be best to increase the horny part, because although you 

 thereby decrease the starch, the valuable by-products (oil and concen- 

 trated cattle food) would be increased at a much greater ratio than the 

 starch would be decreased, and the total value of all the mill products 

 would be greater than with the corn poor in proteid.
