Following his evening address came a discussion of the educational require- 

 ments of Plant Pathologists. Dr. J. H. Faull opened the discussion. After an 

 animated consideration of the various subjects which came within scope of the 

 work of a practising Plant Pathologist it was decided to appoint a committee to 

 draw up recommendations, the committee comprising: Dr. A. H. R. Ruller, Dr. 

 J. H. Faull and Prof. J. E. Howitt. A report will probably be forthcoming at the 

 next annual meeting. It was also resolved that the above committee be authorized 

 to wait upon the Minister of Agriculture to urge the early appointment of a 

 Dominion Botanist who can command the confidence of Plant Pathologists and 

 Agriculturalists generally. 



The papers, given during the sessions covered a wide field and it is impossible 

 to give a detailed account, but an attempt will be made to give the substance 

 of each. 



"Health and Disease in Planis'\, by F. L. Drayton. 



In this paper it was urged that greater attention be paid to physiological 

 studies and to the normal and abnormal structure of plants in order that an 

 intelligent attempt may be made to understand the nature of diseases in plants. 

 In this all those who have the science of Phytopathology at heart will agree with 

 him for that science cannot be allowed to desiccate in a mycological herbarium. 



"Decay in the Timber of Pulp and Paper Mill Roofs", by R. J. Blair. 



The moist conditions obtaining in pulp and paper mills permit of the rapid 

 development of wood rotting fimgi so that roofs require to be renewed every si.x 

 or eight years. The chief fungi concerned are: — Lcntodiiim tigrinitni, Lenzitcs tra- 

 hcnm, and Poria xantha. 



The remedy for such timber decay involves the following four points : — use 

 of timber which is resistant to decay; ventilation to remove excess moisture: 

 liberal dry air heating; and the placing of a layer for heat insulation on the upper 

 side of the roof planks. 



"Butt Rots of the Balsam Pir in Qnchcc Province" , by W. H. Rankin. 



Dr. Rankin explained the dying of Balsam Fir over extensive areas as being 

 due to the Spruce budworm and to Fomes pinicola, the latter giving rise to a butt 

 rot. In most cases he found that the taproot was first infected and that from the 

 taproot the disease spread to the butt. 



"Leaf Blight of the Pine", by J. H. Faull. 



A deathrate as high as 5% was found in some areas of northern Ontario. 

 The symptoms are very similar to winter browning, and in fact many lumbermen 

 speak of it as frost injury. No inoculation experiments were successful. Young 

 trees in most cases recover. 



"Pseudorhiza of Certain Saprophytic and Parasitic Agaricincae" , by A. IL 

 R. Buller. 



Dr. Buller showed that typical pseudorhizae were not uncommon among the 

 Agaricineae and illustrated his paper with lantern slides from photographs. These 

 were of pseudorhiza carefully excavated and photographed in situ.
