Second " Barley.

Fifth " Meadow. 



Sixth " Fallow. 



Seventh " Wheat. 



Eighth " Oats sown with clover. 



Ninth " Pasture or meadow. 



It will be evident, on a little reflection, that no definite rules 

 can be given, and no set of tables devised which shall apply to 

 all soils and under all circumstances. The frequency of any 

 crop in the course of rotation, must, therefore, be determined 

 by a consideration of the character of the soil and subsoil, the 

 amount of manure applied, and the other crops which come 

 in the course.* 



* " In wheat farming districts and with the wheat farmer, who depends 

 for his sales and profits solely upon wheat and wool, the following rota- 

 tion with slight variation, is often adopted. 



Divide all the available land into three, six or nine enclosures: let 

 one-third be always in wheat, one-third in pasture and meadow, and 

 one-third in summer crops well manured, which may be followed with 

 wheat the same fall, or may be put in barley the next spring, and fol- 

 lowed with wheat and well clovered in all cases. The general practice 

 is, to summer fallow the clover after spring pasturing. There should 

 be about one sheep to the acre of all the available land ; the manner of 

 cropping the fallow is important. 



Others make a four years' rotation, letting the clover lay two years, 

 one for pasture and one for meadow. On this system no more ealtle 

 should be kept, or butter and cheese made, or corn, oats or potatoes 

 grown, than is required for the farm use; everything is made subser- 

 vient to the wheat crop." L. B. Langworthy.
