With the same assumptions as in the first variety noticed, the produce of an acre will be 
24-2 tons, allowing the heads to average 10 lbs. Of this quantity, 20'2 tons will be 
water, and 4 dry cabbage, of which a ton will contain 324 lbs. of nitrogenous matter, and 
only 54-8 lbs. in the green state. A ton of the green plant will contain 18• 6 lbs. of 
inorganic matter; the dry, 153*9 lbs.; and an acre will be deprived of 446 lbs. according 
to these calculations. 
The ash contains the following amount of elements in 100 parts:
