The San Jose scale in Canada, I am thankful to say, has not s[)read 

 l»eyond the limits of the area which was known to be infested at the 

 time of our last meetinj?, but nevertheless its numbers have decidedly 

 increased within that area. The injury now being done, it must be 

 acknowl(>dii(Ml, is extreme. Tliis area is comparatively small and lies 

 .south of a line drawn from the extreme western end of Lake Ontario 

 to Lake St. Clair. The Federal Government is watching mo.st jeal- 

 ously every shrub and tree importe(l from countries known to be 

 infested, and all clas.ses of plants upon whicdi the scale is liable to be 

 introduced ai'c fumigated at the border by (rovernment officials, 

 whether this is stated to have been jjreviously done or not. It is but 

 just to state that up to the present tinn^ not a single instance has 

 been found of new^ infestation from stock brought into the country, 

 or of a living scale upon any tree which had been fumigated. Those 

 progressive fruit growers who hav(^ spra^^ed their trees to clear them 

 of the San Jose scale have iiad the greatest satisfaction with the lime, 

 suli)hur, and salt wash, either with or w ithout the salt. K.xperiments 

 are in progress with the New York Geneva station lime and sul[)hur 

 wash, in which the sulphur is combined witii the lime by mixing it, 

 while the latter is being slaked, with a solution of caustic soda or 

 caustic potash. If this combination should prove stable and effective, 

 it will, I believe, be found to ])e one of the most important discoveries 

 in economic entomology. The one great difficulty in the way of get- 

 ting this useful remedy against scale insects adopted is tlie trouble 

 and inconvenience of boiling it from two to three hours to dissolve 

 the sulphur. I regret to say that my own experiments with this 

 wash, like those of all other woi'kers I have so far corresponded with, 

 are incomi)lete. I have fouml that the combination (»f the sulphur 

 with the lime can be brought about ([uickly and without diiViculty, 

 luit as yet I do not knosv how elT«H*t ive the wash thus made is nfton 

 the scale insects. I hope at this meeting to get sonic fu rt her light 

 upon this imj)ortant subject. 



Root maggots of tlu' cabbage, turnip, radish, and onion were xcry 

 destructive in many parts of Canada during the past season, com- 

 plaints of tlieir (lepredalions having been received fnnn both the 

 Atlantic and Pacilic coasts, as well as from many iu)ii'ts in the inte- 

 rior. Satisfactory remedies foi* tlies*^ insects seem still to be desid- 

 erata. For cabbages and cauliHowers, in my experience, the best 

 remedy has been the use of tli(> tarred-i)ai)er disks recommended by 

 I'rofessor Slingerland. \(^xt. to these is the ])ouring of a small <|uan-
