MONTANA STATE BOARD OF HORTICULTURE 73 



season of the year, from states where the disease is known to occur. 



The precautionary measures taken by the U. S. Government to 

 prevent the disease from entering the northwest section, consists of 

 the inspection of all nursery shipments of eastern white pine and 

 Ribes as far as possible and quarantine regulations. Ribes ship- 

 ments from some of the western nurseries have also been inspected. 

 Special importance is attached to shipments which have come from 

 nurseries where the disease has been found, several of which are in 

 the Middle West and many in the East. Fortunately not many ship- 

 ments of eastern white pine have been made into Montana, but there 

 are innumerable shipments of Ribes' from various nurseries. There 

 is at the present time a quarantine ''established against the importa- 

 tion 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 currant and gooseberry plants (Ribes and Gro&sularia) 

 from any part of the United States east of and including the States 

 of Minnesota, Iowa, Missouri, Arkansas and Louisiana." 



Owing to the scarcity of field men during the past season, only 

 a comparatively small part of ^Montana was covered. However, the 

 territory included in the white pine belt was covered, and the number 

 of inspections made in the various counties is as follows : Missoula, 

 552, distributed among 21 towns' and localities; Mineral, 53, among 

 9 towns and localities; Ravalli, 206, among 9 towns and localities; 

 Sanders, 399, among 19 towns and localities ; Flathead, 694, among 22 

 towns and localities, and Lincoln, 33, among 3 towns and localities. 

 This makes a total of 1,937 inspections traced in 83 towns or localities 

 in six counties. Very few of these represented white pine ship- 

 ments. The office has in its files at the present time 8,555 cards of 

 uninspected shipments, distributed among 601 localities, covering the 

 entire State of Montana. 



To date the disease has not been found and no record of its occur- 

 rence has come to the attention of the office. To any acquainted 

 with the topography of IMontana and the limitation of transportation 

 in many sections, one can perceive that a large amount of work has 

 been accomplished, but that a tremendous amount still remains to be 

 done. It is the wish of this' office that the people of the state co- 

 operate in this work, and any one interested should communicate with 

 or ^^sit the local laboratory, where specimens of the disease are on 

 exhibition, and where more information concerning the method of 

 spreading and means of prevention can be obtained.
