The produce of an acre may be estiaialcd by taking 15 lbs. as the average weight of each 

 plant, and assuming that it will occupy a square yard. An acre will produce, according 

 to the estimate, 36 tons, containing 30 tons of water and 6 tons of dry matter. The nitro- 

 genous matter of an acre, according to the foregoing calculation, will be 357 '6 lbs. in the 

 green plant, and 2148 lbs. in the dry. A ton of the green plant contains 15-8 lbs. of in- 

 organic matter, and 139 '38 lbs. in the dry plant. There will be removed from an acre, 

 569 lbs. of inorganic matter. A ton of the green plant contains 1768 lbs. to 232 of dry 

 matter.
