 disked in before next plowing. Never work the soil when 

 saturated with water or during the heat of summer, and 

 never plow in green vegetation. These are three causes 

 for acid soils.

 of the foliage and occasionally .there will be found a 

 great ugly worm called the "orange dog" which is a

 a short time, but none of these troubles are likely to be

The nests of the ants should be broken up by making 

 holes into them by thrusting down a pointed stick and 

 into each hole pouring a tablespoonful of bisulphide of

 immediately with tightly packed earth. Grasshoppers 

 can be killed by scattering around the trees bait made

 make it soft without being sloppy. Grasshoppers show
