then seed each field to the crops in the rotation in regular order, as is 

 shown in the tables. 



Where biennial or perennial crops enter into the rotation, as is the 

 case with rotations Nos. 1 and 2, it will be necessary the first year to 

 supply some other crop in the place of the perennial, which, when the 

 rotation is once started, will be carried on from the previous year. 

 For instance, in the case of the 6-year rotation (No. 2) the farm 

 should be divided into six fields of equal area, as shown. Field A 

 should be planted to corn, field B to wheat, and field C should be 

 seeded to brome-grass. Field D should also be seeded to brome- 

 grass, as it will remain as a meadow during the following year. 

 Field E, which should be in brome-grass, but would be broken up after 

 the grass was cut, should be planted to some other crop. It is not 

 important what this crop should be, except that if the rotation has 

 been adopted with a view to furnishing the proper quantity of hay it 

 would be desirable to have this field put into some kind of an annual 

 crop that could be cut for hay. Millet, oats and peas sown together, 

 milo, or some of the other nonsaccharine sorghums, could be used for 

 this purpose. Field F would be sown to oats, barley, emmer, or 

 wheat, as shown. After the first year the rotation would go on 

 without further interruption, except that in the case of a failure of the 

 grass to catch, some annual could be substituted without in any way 

 interfering with the general plan of the rotation.
