with the forest industries, the provincial governments who admini- 

 strate almost 80 percent of Canadian forests, and other associated 

 agencies. The regional laboratories also contribute technical and 

 advisory services to provincial governments and industries in disease 

 control programs, in the application of pathological procedures to 

 inventory and utilization practices, and in the appraisal of the results 

 of control operations. Instruction in forest pathology is frequently 

 provided to universities and forest ranger schools. 



Other Federal Government Departments. — In the Department 

 of Agriculture, the mycology unit of the Plant Research Institute 

 conducts taxonomic studies of fungi and provides identification serv- 

 ices. The work of Dr. M. K. Nobles with wood-destroying fungi is of 

 particular interest to forest pathologists. This institute is also respon- 

 sible for frost resistance studies relating to trees. 



In the Forest Products Research Branch, Department of Forestry, 

 research is undertaken at both the Ottawa and Vancouver laboratories 

 on stain and decays of wood products in storage and service. 



Provincial Governments. — The provincial forest services provide 

 experimental areas, building sites, and transportation services; their 

 personnel cooperate in forest insect and disease surveys and frequently 

 participate in research projects with the Department of Forestry and 

 other agencies. Forest pathologists will be interested to learn that 

 many provincial governments now obtain information on decays as 

 a regular part of forest inventories, with the Forest Entomology and 

 Pathology Branch staff contributing guidance in field and laboratory 

 techniques. 



Universities. — An important contribution of the universities to 

 forest pathology in Canada is the training and development of re- 

 search personnel. In addition, in forest disease research, Dr. J. E. 

 Bier and his students at the University of B.C. are engaged in studies 

 of bark moisture in relation to the development of canker diseases 

 caused by native, facultative parasites (7). The morphology of 

 dwarfmistletoes is being examined by Dr. J. Kuijt, University of 

 B.C. At the University of Toronto, E. Jorgensen is investigating 

 diseases of forest plantations, particularly root rot caused by Fomes 

 annosus. At Queen's University, Dr. H. M. Good is concerned with 

 decay organisms of hardwoods and Dr. G. Krotkov is collaborating 

 with Dr. V. Slankis of the Laboratory of Forest Pathology, Depart- 

 ment of Forestry, Maple, Ontario, on studies of myeorrhizae. 



Research problems of particular interest to the Forest Entomology 

 and Pathology Branch, but requiring facilities not available at re- 

 gional laboratories, are occasionally conducted by university staff 

 members under Department of Forestry extramural research financial 

 grants. Funds for forest disease research at universities mav also 

 be provided by agencies such as the National Research Council, On- 

 tario Research Foundation, and the forest industries. 



International Considerations. — Forest pathologists in Canada 

 maintain close contact with their colleagues throughout the world 

 through correspondence and through participation in F.A.O. work- 

 ing groups, various international committees and societies, attendance 

 at world scientific congresses, and by exchange visits with scientists 

 in other countries. Through the Colombo Plan, scientists of member 

 countries are invited by the Canadian Government to engage in study 

 tours of research programs and facilities. At the present time we
