more of the year than if only one kind of crop were raised. 

 This keeps the farmer employed all the time, and if he has to 

 keep hired help he can engage it by the year, which is better 

 than hiring it by the day. 



Notable Rotations. — One of the oldest and most noted 

 systems of rotations is the Norfolk rotation. This was devel- 

 oped in Norfolk County, England, and has been used there 

 for many years. It is a four-course rotation consisting of tur- 

 nips, barley, clover, and wheat in the order named. If we 

 study this rotation we shall see that it is helpful in the ways 

 mentioned above. It contains a leguminous crop, the clover; 

 it has deep feeding crops, the clover and turnips ; it has shallow 

 feeding crops, the barley and wheat; and none of these crops 

 is troubled by the same kind of insects, plant diseases, or 

 weeds as the others. 



Another noted rotation is the Terry rotation. It was used 

 by Mr. T. B. Terry, in Ohio, for building up a run-down clay 

 farm. It consists of clover, potatoes, and wheat. In this 

 rotation we have clover as the legume and deep feeding crop, 

 potatoes, which also feed through a large volume of soil, and 

 wheat, which is a shallow feeder. 



In the corn-belt states corn, oats or wheat, and clover is a 

 common rotation. In many cases the rotation is corn, oats, 

 wheat, and clover, and sometimes timothy is sown with the 

 clover, and the land is kept in clover and grass for two or 

 more years. 



Now, a rotation to be a proper one must be suited to the 

 climate and soil of the region in which it is to be used. It 

 must also be suited to the labor and market conditions. In 

 very few cases could the farmers in the United States use the 

 Norfolk rotation, for the turnips would have to be planted in
