Mistletoe Control 577 



(It may be of interest to add that the mistletoe trouble extends into Canada 

 as far north as the 54° of latitude at least. In the Pines, Nesbit, Fort k la 

 Come, Sturgeon and Big River Forest Reserves, the Jack pine is often heavily- 

 infested. In the frontispiece we bring examples from the Nesbit Reserve 

 near Prince Albert. The Acting District Inspector, Mr. E. H. Roberts, finds the 

 infection mostly occurring in the pure Jack pine stands, on both young and 

 old trees alike, most noticeable on older trees from 25 years up, and most in 

 open stands. A relation to any particular physical condition of environment 

 was not noted, but fire scars and exposure of tissues by rabbits seem to favor 

 the infection. These sand areas have been kept depleted by fire of any humus 

 cover. — Editor.)
