fifth years, grass. Or sometimes, first and second year Indian 

 corn and followed as above ; or otherwise, first year corn, second 

 year potatoes, third year small grain and grass seed, fourth, fifth 

 and sixth years grass. The cultivation of esculent vegetables, 

 such as ruta-baga, mangel-wurtzel, carrots, &c. may be consid- 

 ered as accidental. These crops form no part of a regular or 

 systematic rotation. Several farmers having entered with me 

 into some calculation of the proceeds of their farms under this 

 system, I shall subjoin some of these estimates. The expenses 

 of cultivating several of the crops, such as corn, oats, wheat, 

 barley, &c. having been given in detail in previous parts of my 

 Report, the results only will be subjoined. The cost of man- 

 ure is always included in the account of the first crop ; but its 

 benefits extend through several years. 



1. In Tyngsborough, the rotation is — 1st year, corn ; 2d 

 year, rye, with grass seed ; 3d, 4th and 5th years, grass. 



Balance in favor of corn, 50 bushels per acre, all ex- 

 penses allowed, ....... 15 87^

Interest on land, valued at $100 per acre, 5 years. 

 Net profit on a five years' course upon one acre, 



Tyngsborough. — I add the amount of another farmer in the 

 same town. These estimates were obtained without one farm- 

 er's knowing what return any other had made.
