QUANTITY OF SEED REQUIRED. 



191 



NOTE. From the above table it appears that the acre 

 which, by cropping with wheat, would yield a given weight 

 of starch, sugar, and gum, would, when cropped with bar- 

 ley or oats, yield one-fourth more of these substances with 

 potatoes, about four times as much, and with turnips eight 

 times the same quantity. In other words, the piece of ground 

 which, when sown with wheat, will maintain one man, 

 would support one and a quarter if sown with barley or 

 oats, four with potatoes, and eight with turnips in so far 

 as the nutritive power of these crops depends on the starch, 

 sugar, and gum they contain.
