 crops in succession after the turnips. 



But it commonly happens in the history of agri- 

 culture that improvements are adopted only very

 exception to the rule. Certain difficulties also arose 

 which Townshend did not overcome. Turnips were

 Phyllotreta nemorum, commonly known as the Fly, 

 which in dry weather sometimes almost destroyed 

 the crop and left the animals without any food for 

 the winter. Red clover (the ordinary variety grown) 

 will not always grow ever}' fourth year, but sometimes 

 fails after the second or third course for some reason 

 which is still obscure. Thus under the combined 

 attacks of Turnip Fly and of Clover Sickness the 

 farmer might find himself >vith a number of animals 

 on his hands and no food for them, an awkward
