ioo Forests and Trees 



A spray pump will be necessary for their application 

 and if much work has to be done, such as the spraying of 

 the trees on the streets of a town, then one driven by a 

 gasoline engine will be necessary. There is a great variety 

 of these pumps on the market and they may be procured 

 through any hardware merchant or seedsman. The 

 cheapest to be effective for trees is a force pump to be at- 

 tached to a barrel. '.-
