Canadians and Americans Discuss 

 Problems Together 



Forestry Conference at Washington has Important Results 

 White Pine Disease the Chief Subject. 



The Annual Meeting of the Am- 

 erican Forestry Association at Wash- 

 ington, D.C., on January 18 and 19 

 was attended by a group of Can- 

 adians including R. H. Campbell, 

 Director of Forestry, Clyde Leavitt, 

 Forester, Commission of Conserva- 

 tion; Ellwood Wilson, Forester of 

 the Laurentide Co.; G. C. Piche, For- 

 ester of Quebec; E. J. Zavitz, For- 

 ester of Ontario; P. Z. Caverhill, 

 Forester of New Brunswick; Avila 

 Bedard, George Maheux, G. A. 

 Gutches, Robson Black, Secretary of 

 Canadian Forestry Association, and 

 others. 



Canada Heard From. 



Three important subjects were on 

 the programme: "Recreational Uses 

 of National Forests and National 

 Parks"; "The White Pine Blister 

 Disease"; and "Stopping Importa- 

 tion of Tree and Plant Pests." While 

 each subject attracted deep interest 

 and received most able discussion, 

 it is probable that the amount of 

 public alarm incident to the white 

 pine menace made most listeners 

 particularly receptive to the papers 

 dealing with the Blister Rust. The 

 subject was treated from the point 

 of view of territories affected, Mr. 

 Clyde Leavitt speaking for Canada, 

 W. P. Wharton for New England, 

 J. B. White for Hudson to Mississippi, 

 and E-. T. Allen for the Pacific Coast. 

 Mr. Leavitt estimated the value of 

 Canadian white pine at upwards of 

 two-hundred millions of dollars. He 

 told of the location of known infec- 

 tions, the danger of a spread into 

 the commercial pine areas, and de- 

 scribed the efforts to hold the damage 

 to the smallest possible proportions. 

 Mr. S. T. Detwiler, U.S. Forest Path- 

 ologist, estimated the value of currant 

 and gooseberry bushes in all of the 

 United States at 48 million dollars; 



the stumpage value of white pine was 

 seven to ten times that amount. 

 There were 11 million dollars worth 

 of the ribes in the States thus far 

 infected with Blister Rust whereas 

 in the same territory the annual value 

 of white pine cut was between 40 and 

 50 million dollars. 



Guided By Local Evidence. 



Mr. C. R. Pettis, Superintendent 

 of Forests for New York States said 

 that there were 10 million white pine 

 in the nurseries of his state and it 

 was not proposed to burn them all 

 up. He had found a large area of 

 the Adirondacks where no currants 

 or gooseberries grew and proposed 

 to plant that section in white pine, 

 despite the alarm over disease. He 

 preferred to be guided by local condi- 

 tions in selecting trees for planting, 

 and objected to disrupting the whole 

 reforesting movement by a general- 

 ized condemnation of white pine 

 planting. 



The meetings during the two days 

 were conducted by President Charles 

 Lathrop Pack with remarkable suc- 

 cess. The year's work of the Am- 

 erican Forestry Association once more 

 testified to the skillful guidance of 

 Mr. Percival S. Ridsdale, Executive 

 Secretary. 



The following Resolutions have 

 particular interest for Canadians, Mr. 

 R. H. Campbell, Ottawa, having act- 

 ed as a member .of the Resolutions 

 Committee: 



To Save White Pine. 



Whereas — The Pine Blister threat- 

 ens to greatly injure the white pine 

 forests of Eastern North America, 

 and is a growing danger to the white 

 pine timber of the West, and its 

 origin, propagation and transmission 

 being now generally understood.
