The White Pine Blister Rust. 233 



the foremen noticed a peculiar coloring of the stems and soon after 

 referred the matter to the writer. Some three-year old transplants 

 which showed evidence of the disease were secured and at the 

 same time an examination was made of some white pines, which 

 had been imported from Germany as two-year old seedlings the 

 previous year, and transplanted in a nursery at Lake Clear Junc- 

 tion. In this nursery several specimens, which showed typical 

 forms of the disease, were found. Dr. Perley Spaulding, of the 

 Bureau of Plant Industry, was present and identified the disease 

 as Peridermium strobi. Later, specimens were sent to* Prof. 

 Arthur, of Purdue University, Prof. Stewart, of the Geneva 

 (N. Y.) Experiment Station, Prof. Jones of the University of 

 Vermont, Dr. Metcalf of the Bureau of Plant Industry, also Pro- 

 fessors Farlow and Thaxter of Harvard University, all of whom 

 confirmed the previous identification. 



A casual examination by Dr. Metcalf and Dr. Spaulding, as- 

 sisted by the various state forestry officials soon located the dis- 

 ease in Vermont, Massachusetts and Connecticut. 



As soon as Commissioner Whipple became acquainted with the 

 situation he immediately called a conference of the forestry inter- 

 ests, inviting representatives of state and private work, from 

 Maine to Maryland and west to Ohio, also of the Forest Service 

 and Bureau of Plant Industry. This Conference met in New
