red. A little later this amber will have become much darker and have a 

 green shade. When this condition is reached the pumps do not clog; the 

 work of applying it is not so objectionable and if the trees be well covered a 

 good result is guaranteed. 



As far as we have gone I have discussed this question entirely from the 

 standpoint of a fruit-grower which in your judgment may seem out of place 

 at this meeting. This is the only means I now have of reaching the people 

 and my desire to encourage and assist them must be my apology. 



Division No. 5 — London District. By R. W. Rennie. 



No case of serious injury by insects has been reported to me this season. 

 Of course, we have had all our old enemies with us, but not in larger num- 

 bers than usual, excepting probably the Tent caterpillars (Clisiocampa Am- 

 ericana) which appeared in large numbers early in the season, but which 

 seemed lo confine themselves mostly to the wild cherry, orchards being 

 comparatively free from them. 



One pest, which is ordinarily called "E-ed Spider," and is quite com- 

 mon in gardens of sandy soil, which also is not very particular as to its food 

 plants, has selected a new one this year, at least it is the first time I have 

 observed them on this plant, namely, the tomato. 



About the first of August I noticed one of my tomato plants looking un- 

 healthy, and upon investigation found it had been attacked by these mites ; 

 some days afterwards, while walking in the country, I noticed some tomato 

 plants which appeared to be suffering from the same cause, and upon examin- 

 ation such proved to be the case. Several other places were also noticed dur- 

 ing the season. 



In my own garden the plants attacked did not set any fruit above the 

 second cluster of buds, the leaves curled in tightly, very much like the leaves 

 of the shrub-snowball, when attacked by Aphis, making it almost impossible 

 to apply any remedy. 



If the pest should take generally to the tomato, it will mean serious 

 loss to private and market gardeners, as it will be very difficult to apply any 

 remedy in the fields owing to the leaves curling so tightly and the mites be- 

 ing on the inside. 



DISCUSSION OF THE DIRECTORS' REPORTS. 



In the discussion which followed upon the reading of the Directors' re- 

 ports, the first subject taken up was that of the remedies employed for the 

 San Jose Scale. 



Dr. Fletcher stated that he had used the lime and sulphur wash after 

 slaking only, without boiling, on Snowballs (Viburnum) for Aphis with good 

 results, but had not tried it f'or the San Jose Scale. 



Mr. Fisher said that one great cause of failure with this wash was that 

 the boiling was not continued long enough ; the mixture was not fit to use till 

 the green shade appeared. This he had learnt as the result of repeated ex- 

 periments. In California the boiling process was continued for three hours, 

 but he had obtained the same results in two hours. The most effective mix- 

 ture was made with the proportions of half a pound of sulphur to one pound
