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 IS - 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 :
