/.KEEPING ACCURATE ACCOUNTS. 



This is as essential on the farm as in the bank 

 or store ; for the farmer should know just what 

 his profit is, and what crops pay best. This can 

 be known only by keeping account of all work 

 done and money expended in putting in and in 

 harvesting the crop, and in the feeding or mar- 

 keting of it. 



EXERCISE 9. (a) Each student should carefully pre- 

 pare an original plan for a course in rotation upon a 

 poor soil, and another upon a fertile soil, in his own 

 vicinity. 



() Give directions for the preparation of the soil as 

 regards fertilization and tillage. 



(c) Give directions and reasons for the disposition of 

 each of these various crops. Is it to be fed, or sold ? 

 If fed, in what condition green or dry? To what ani- 

 mals ? 



(a) Make an estimate of the probable cost of seed and 

 work, and of the value of the crop ; if sold; if fed ; and 

 calculate the gain. 



(e) Read and discuss in class each plan, with reasons. 

 Be able to defend every point taken.
