It becomes evident from a study of these figures that quality of 

 soil or variety, probalily chiefly the former, produces considerable 

 differences in the percentages of moisture and starch as shown by 

 the great superiority of the Shelburne samples. 



For better study of the influence of the various treatments, the 

 results of these moisture and starch determinatioi^s have been vari- 

 ously combined and averaged as shown in the tables below.
