SAVE THE WHITE PINE 



Canada's two hundred million dol- 

 lars worth of white pine is menaced 

 by a deadly disease, "Blister Rust." 



Every reader of the Canadian For- 

 estry Journal, residing near white 

 pine areas has a public duty to per- 

 form in 'scouting' for infections of 

 the disease. A special pamphlet, 

 with graphic illustrations, has been 

 issued by the Forestry Association. 



Learn what the disease is and how 



it develops on white pine and on the 

 'host' plants, the currants, and goose- 

 berries. The latter are essential to 

 the transmission of the disease for it 

 will not pass direct from pine to pine. 

 Destruction of the 'host' plants will 

 stop the progress of the Blister Rust. 

 All trees infected should be destroyed 

 by their owner. 



Send your name to the Association 

 office, 119 Booth Building, and secure 

 a few copies of the pamphlets.
