73 2 CONNECTICUT EXPERIMENT STATION REPORT, IQ/X^-IQIO. 



appearance. During May and June four inspectors visited 

 twenty-six plantations, inspecting about 425,000 seedlings, and 

 made very careful examinations for the rust, in many cases 

 examining every individual seedling. In spite of this thorough 

 examination, not a single rusted plant was found! No doubt 

 the severe drought of the preceding year had killed off those 

 seedlings weakened by the rust, if such existed. Of course 

 it is possible that examination another year might reveal a few 

 rusted plants, as it is usual for the seedlings to go one or 

 possibly more years after infection, before the secial stage of 

 the rust appears on them. 



During the years 1907, 1908 and 1909, there were imported 

 into the state, chiefly from Germany, under the supervision of 

 the station's forestry department, about 640,000 white pine 

 seedlings, which were set out in fifty-five different localities, 

 and private individuals have imported at least 100,000 more. 

 All of these seedlings, except about 95,000 set out mostly in 

 small lots in twenty different localities, have now been inspected 

 once or twice for the rust. No doubt, too, at the time they 

 were set out the men would have discarded any specimens 

 showing evidence of the rust. In all of the plantations exam- 

 ined, watch was kept for any signs of currants or gooseberries 

 in the vicinity of the pines, and these were destroyed when 

 found. Fortunately, species of Ribes in a wild or escaped state 

 are comparatively rare here, so that even if this rust occurred 

 on the pines, it would be much more difficult for it to pass 

 to these hosts than in some of the more northern states 

 where they are more frequent. In 1910 the station did not 

 import any white pines because of the danger of bringing in 

 this rust, and only one lot, to our knowledge, was imported by 

 others. Examination of these showed no signs of the rust. 

 From now on it is probable that most of the seedlings set out 

 will be native grown stock, as plenty of this seems to be in 

 evidence at fair prices. There does not seem to be much likeli- 

 hood, therefore, that the rust will obtain a foothold in the 

 state, though watch will still be kept for it. Anyone finding 

 suspicious specimens should send them to the station for exami- 

 nation. 



Infected white pine seedlings, out of the season when the 

 fruiting stage appears, may be recognized in a general way
