7. In addition to nursery work, there should l)e a state wide sur- 

 ve\- of Minnesota to learn whether this disease occurs in sections other 

 than those examined this year. 



<S. An\- work towards eradication in Minnesota is futile unless 

 Wisconsin, in which state the disease is known to exist, co-operates hy 

 continuous and efficient ettorts at eradication within her own houn- 

 daries. This statement is also ajjplicable to any other adjacent state in 

 which the disease occurs. 



'>. Purchasers of stock from nurseries should realize that an 

 Insi)ector's certificate is not a i^uarantee that pines in that nursery are 

 free from White fine lUister Rust, since as previously explained the 

 disease may be present in the tissues of trees and not he a])ixirent 

 upon the surface. 



10. The relation nf X iirscrynicii to the Tcdcral 1 1 orliciiltiiral 

 Board ill coiiiicctioii with this disease. 



The l*"ederal Horticultural IJoard in a commendable etiV)rt to save 

 the five-leaf pines in the large area west of the Continental I )i\ide ha\e 

 asked (not recjuired, Ije it noted) nurserymen in .Minnesota with those 

 of manv other states, not to ship pines, currants or gooseberries 

 west of the Dakotas, and broadK s])eakin,<4- west of a line drawn south 

 from those states. As State Insjjector and collaborator with the b"ed- 

 eral I'oard, the writer urines nurserymen to heed the suo-.Qestion cominoT 

 from W'ashinj^ton, but expresses the hope that this recpiest on the i)art 

 of the Hoard may be modified. While the Board has prevented the 

 introduction of five-leaf pines from Europe, it has placed no cpiarantine 

 u])on ])ines beino shipjjed from the h\e or more states in the east known 

 to be infested. Further, there is no restriction at present upon the 

 entrance of currants and gooseberries into the I'nited States from 

 lun-ope. This unrestricted entrance of currants and gooseberries is 

 probably ])ermitted because so far practically all of the evidence as to 

 spores being carried over on dormant bushes is neg'ative. Such being 

 the case and with the above facts before us, it would a])]iear that dor- 

 mant currants and gooseberries might be shipped with safet\ into the 

 states, or i^ortions of states lying east of the l)i\-ide, I'^astern ^^Fon- 

 tana. for exam])le. 



Personally, we should like to see all foreign importations of nur- 

 sery and ornamental stock into the United States prohibited for a num- 

 ber of years. The White I'ine 1 Ulster Rust was introduced and dis- 

 trilmted before our citizens were aware of its presence. ( )ther diseases 

 as bad or worse might be brought in at any time, to de\elo]) later and 

 cause thousands of dollars worth of damage. In this connection we
