Book excerpt: Excerpt from A Summary of the Prevalence of Plant Diseases in the Dominion of Canada, 1920-1924 A plant disease survey functions as an intelligence service for plant patho logy. Information on the geographical distribution of the plant diseases of a country is gradually built up, the economic importance of each disease is recorded, their spread or stationary character in any given locality can be traced, their prevalence and dates of occurrence in successive years can be noted and Often correlated with the prevailing weather conditions. Notes are also made on observed differences in varietal susceptibility and resistance. It serves as a medium for recording the appearance of diseases new to the. Country and stimu lates a keenness for the Observation of new diseases. It aids in the selection of problems for study, especially for anyone who is new to a district; and indicates the problems which require special demonstrations and extension work relative to control measures. Lastly, it helps to educate the public on the importance of plant diseases, thereby assisting in the granting of money for research and extension work leading to the formulating of control measures and their adoption. It is Obvious that the information required for a plant disease survey of any country cannot be collected by any one institution. In Canada, the Domin ion Plant Pathological Service is the obvious medium for the collection and publication of such a survey, but the members of its staff are necessarily too few in number to make the survey in any way comprehensive and we have been fortunate in obtaining active co-operation from other sources in the collection of data. These include provincial institutions in which plant pathological and botanical work is being conducted, a privately endowed university, Dominion Experimental Farms and Stations, and certain private individuals who are capable of giving reliable information. We have a country of immense size, comparatively thinly populated, and at the best the number of collaborators with sufficient knowledge Of plant diseases to supply information for such a survey is necessarily small, in proportion with the area to be covered, but we feel that a good start has been made, and as time goes on, these conditions will improve and the value of the survey will become cumulative.
