1923] Variation of Protein Content of Corn 61 



Corn H, Blanchard Prolific. The seed of this sample was grown in North Carolina 

 in 1921, and the sample grown in North Carolina in 1922. 



Nitrogen Protein 



No. 1. 1.492% 

 No. 2. 1.501% 

 Mean 1.497% 9.36% 



Corn I, White Plume. The seed of this corn Avas grown in North Carolina in 

 1921, and planted in West Virginia in 1922, same as B, but this sample, I, 

 did not mature.

Corn J, White Plume. The seed of this corn was grown in North Carolina in 

 1921, sample grown in North Carolina in 1922, same as A, but this sample, 

 (A) did not mature. 



Nitrogen Protein

Future Plans 



It is our purpose to extend this investigation for a number of 

 years, seeking to eliminate the errors that may vitiate our results. 

 We shall study a larger number of varieties, and use extreme care to 

 preserve the integrity of each. 



We shall preserve samples of all the corns analyzed, and, to sim- 

 plify reporting, will employ the same notation each year. A will rep- 

 resent White Plume grown in North Carolina; A' a special analysis 

 of the same sample, of the same corn selected in a different way, and 

 A" an analysis of a different sample of the same corn. B will repre- 

 sent White Plume grown in West Virginia, seed from North Carolina. 

 Each corn year after year will be represented by the same letter. 



Next year we shall extend our investigation to include fertilizers 

 and climatic changes, later we shall investigate soils. 



At present we shall report only the facts, and withhold any con- 

 elusions until we come into possession of more accurate information.
