WHITE PINE BLISTER RUST QUARANTINE 



An exceedingly destructive disease of pine is prevalent in some 

 parts of the East which, if introduced into Montana, would almost 

 certainly do great damage to our forests of pine. This disease has 

 not yet reached Montana. It is hoped that by prohibiting the 

 importation of pines and of currants and gooseberries, which are 

 alternate hosts of the disease, white pine blister rust may be delayed 

 or even entirely prevented from gaining admittance into Montana. 

 The quarantine follows : 



QUARANTINE PROCLAMATION 



Whereas, The fact has been determined that a dangerously injurious disease 

 known as the Wliite Pine Blister Rust (Peridermivtm strobi Kleb.) exists and 

 is prevalent in portions of the eastern part of the United States as far west 

 as and including Minnesota; and 



Whereas, There is danger of the introduction of this disease into the great 

 white pine forests of the State of Montana through shipments of five-leaved 

 pines and currants and gooseberry plants: 



NOW', THEREFORE, J, S. V. Stewart, Governor of the State of Montana, 

 under and by virtue of the authority conferred upon me by Chapter 61 of the 

 Session Laws of the Thirteenth Legislative Assembly, do hereby declare and 

 proclaim that a quarantine be and hereby is established against the importation 

 into the State of Montana of white pine (Pinus strobus), stone pine (P. cembra), 

 limber pine (P. flexilis) and any other five-leaved pines, and currants and 

 gooseberry plants (Ribes and Grossularia) from any part of the United States
