34 CONTINUOUS CROPPING 



plenty big enough. In fact, some people say that for 

 two light horses, or deep work, nine tines are enough ; 

 but it is better to get the bigger implement, as it is 

 quite easy to remove two tines if for some jobs the 

 draught is too heavy. 



There are also spring- tined harrows with second 

 auxiliary springs, or helpers, as they are called, fitted 

 to the tines. These double-spring harrows are a few 

 shiUings dearer, but well worth the extra cost. 



Another thing which makes the spring-tined harrow 

 an acceptable implement for the small man is its com- 

 parative cheapness. A harrow of the size indicated 

 above can be obtained for about £2 los. or £3. 



When we come to discuss the cultivation of other 

 crops we shall see how essential a spring-tined harrow 

 is for the economical tilling of the land.
