THE POTATO 89 



way as the following: Land which is used for 

 potatoes should, immediately after harvesting of 

 the crop, be treated to a liberal application of farm 

 manure, if it can be obtained, and plowed with lap 

 furrow. The plow can well run an inch deeper 

 than it did the preceding year when the land was 

 prepared for potatoes. In the spring the soil will 

 have crumbled by the frosts, and should then be 

 thoroughly worked by frequent harrowings with 

 some such tool as a disk or spading harrow. It 

 should then be smoothed with an Acme harrow, or 

 some other tool, and seeded to grain. If it is 

 designed to grow only a single crop of grass, it is 

 best at the time of seeding to sow clover with the 

 grain. If, however, it is designed to remove two 

 crops of grass, it can be seeded with a mixture of 

 clover and timothy. The grain crop will be har- 

 vested the first year; the second season the crop 

 will be chiefly timothy; the third it will be timothy 

 and clover, and at the end of the two or three years, 

 whichever plan is followed, there will be in the field 

 in the fall a good stand of second growth clover. 

 This should not be cut or fed, but should be plowed 

 under, and this is all the more important if the 

 piece has not been treated with farm manure. 

 This fall plowing should be with lap furrow and 

 the following spring it should be thoroughly worked 

 with the disk and smoothing harrows in order to 

 get ready for planting. 



"It may in many situations be desirable to fol- 

 low the grass crop with corn, and then follow with 

 potatoes. The same thorough preparation will be 

 of advantage to the corn crop. The land for the 

 corn should be liberally fertilized. Farm manure 

 will be again used in this part in the rotation to 

 advantage. The corn must be overfed in every
