72 THE AMERICAN PEACH ORCHARD 



The spring-tooth harrow is especially adapted to 

 heavy gravelly soils or those which have a con- 

 siderable amount of loose stones. On such land it 

 is invaluable and is to be used almost exclusively 

 for everything except the early spring cultivation. 



On gravelly land, or soils subject to surface bak- 

 ing, the acme harrow often serves a very useful pur- 

 pose. It is particularly adapted to the production of 

 a suitable dust mulch on refractory soil. But the 

 use of this tool seems to be largely a matter of per- 

 sonal taste, some men preferring it, while other men 

 choose not to use it at all. 



SPRING-TOOTH HARROW 



The smoothing harrow or spike harrow is most 

 efficient of all for producing and maintaining a dust 

 mulch on light land which is in a good state of cul- 

 tivation. It will cover more acres of land in a day 

 with less wear and tear of horse flesh than any 

 other. 



Various weeders are supplied by dealers and are 

 well liked by some men. As a rule they are avail- 

 able only for very light cultivation, unless the soil 

 is in the very pink of condition.
