1919-20 DEPAETMENT OF LANDS, FORESTS AND MINES. 119 



distribution of trees and have made sonie very good plantations on Avaste portions 

 of their farms. 



This last autumn a three-acre mixed hardwood plantation was made with the 

 intention of experimenting on the relative values of the various hardwoods in 

 artificial reforesting. 



During the past season about forty thousand trees were shipped out to private 

 planters. This is far below our pre-war output as our distribution at one time 

 had reached about half a million trees. We have had difficulty in securing reliable 

 seed of the kind of trees desired in connection with this work and it will take at 

 least two years to reach a reasonable supply of nursery stock. 



The work at this station, which has been held up during the war, should now 

 be placed on a better basis. This will require improvements in buildings, a better 

 watering system, more seed bed areas, in fact, a general enlargement of the plant 

 if the growing requirements for trees are to be met. 



The following is an approximate list of the nursery stock at the Provincial 

 Forest Station in Norfolk County: 



Scotch Pine seedlings 600,000 



Scotch Pine transplants 40, 000 



White Pine transplants 30,000 



Larch seedlings 50,000 



Larch transplants 40, 000 



Miscellaneous conifers, as red pine, jack pine, cedar, etc 80,000 



Miscellaneous hardwoods, as elm, sugar maple, white ash, black 



walnut, etc 100,000 



In addition to the above stock, fifty bushels each, of red acorns and black 

 ^walnut were collected and planted this autumn. 



Hi. Forest Pathology. 



The work in connection with tree diseases has been chiefly confined to the 

 eradication of Ribes (currants and gooseberries) at the forest station in Norfolk 

 land the investigations of Dr. Faull into diseases affecting trees in the Timagami 

 region. 



As indicated last year the general eradication of diseased Eibes cannot be 

 carried out on a large scale throughout Ontario, but our efforts should be directed 

 towards local control wherever white pine values warrant the expenditure. The 

 work of eradication is being carried on at the Provincial Forest Station in Norfolk 

 County. About 500 acres have been cleared of Ribes and it is expected that white 

 pine can be grown at this station with little danger of infection. Last year the 

 Department inaugurated work of investigation into the diseased condition of pine 

 in the Timagami region. This work was continued this season and I am glad to 

 report that valuable information has been obtained in respect to the " needle 

 blight " which has become so prevalent in parts of Ontario. A report upon this 

 work follows :

Sulphur Fumes. 



In the last week of May a trip was made into Cleland Township in the 

 District of Sudbury for the purpose of observing the effects on the coniferous 

 forest of sulphur fumes from winter roast beds located from four to six miles 

 distant. The same area had been visited the preceding September in order to
