From the foregoing list, which does not include short notes, book notices and other 

 items of interest, it will be seen that the magazine covers the whole field of systematic 

 entomology and contains articles of importance by well-known authorities on most of the 

 orders of insects. It has become so necessary to the working Entomologist that there is 

 a constant demand for complete sets of the volumes from the beginning and the Society 

 has in consequence been obliged to reprint several of the earlier ijumbers. 



SAN JOS]^ SCALE DISCUSSION. 



At the request of the President, Mr, C E. Fisher, of Freeman, Ont., the Provincial 

 San Jo'6 Scale Inspector, stated that he was present by direction of the Ontario Depart- 

 ment of Agriculture, and was willing to give any information at his disposal with regard 

 to the prevalence of the San Jos^ scale in the Province, and the work which had been 

 done daring the past season. He regretted to say that the state of afiairs was not as 

 favourable as he could wish, and that the scale was now kaown to be present in many 

 districts where it had not been discovered last year. Many experiments had been tried 

 by instruction of the Department to see if a practical remedy could be discovered to con- 

 trol the insect instead of the drastic measure of cutting down the trees. He was glad of 

 the opportunity to let the members of the Entomological Society know what the general 

 trend of his experiments had been. To begin with he would make the statement that the 

 infestation of Ontario orchards by the San JoE^ scale was a far more serious matter than 

 fruit growers of the Province yet realiz'^d. 



The following is a condensed summary of M.}. Fisher's sddress : 



A great deal was said at the last annual meeting of the Society about the value of 

 whale-oil soap as the best remedy for the San Jo£e scale, and particular mention was 

 made of the satisfactory condition of orchards now standing on Catawba Island, which 

 had formerly been badly infested by the scale. I therefore took great pains during the 

 past summer and carried out many careful experiments with this material, using the 

 strength recommended as the best, namely, 2 lbs. of whale-oil soap to one gallon of warm 

 water, as well as other quantities. When a tree was known to be infested it was treated 

 thoroughly with 2 lbs. to the gallon, and all trees in the immediate neighbourhood were 

 also sprayed with a solution of l^ lbs. to the gallon. On other trees kerosene emulsion 

 or crude petroleum were used, and careful notes taken of their effects upon the tree and 

 the scale. With regard to the soap, the results were rather disappointing. In no case 

 was the scale entirely eradicated, even when the soap was applied with the greatest care, 

 according to the formula. Some trees where the full strength of 2 lbs. to the gallon was 

 used are still infested, and the infestation is of about the same extent as at the beginning 

 of the season. The scale was certainly reduced on cherry trees, and it was noticed that 

 the soap had an excellent effect in clearing these trees of aphids. The treatment was 

 applied just at the time the buds were bursting, when most people would think it was 

 too late to use it without doing injury to the trees, but I found that no barm was done 

 even when many of the blossoms were open. As a rule there is too much blossom on 

 trees, and if some of this is destroyed it is an actual advantage, therefore this late spray- 

 ing may be very beneficial. We have noticed that the young scales will move out on to 

 a part of the tree whicb had been sprayed in the spring with the soap mixture, and will 

 settle there and multiply. On the 18th August last I made an application, at Niagara, 

 on a very badly infested tree, one, in fact, which was entirely covered by a moving mass 

 of young crawling scale insects, walking aU over the tree trying to find a place to settle. 

 The soap was applied to the tree with a whitewash brush, with the object of finding out 

 how reliable the soap was, and a little later a second application was made. I examined 

 the tree again about the middle of November, and I think I had the nicest example of
