" With regard to results of our work, so far as is to be gathered from the reports 

 which 1 have received from February up to date, I consider I am juntified in saying 

 that the Paris green treatment was quite a success wherever we know that it was 

 applied in the proportion recommended, and with tolerable sprayers." Mr. C. D. Wise, 

 Superintendent of the Tocldington Fruit Farms, says : Paris green is the onl}^ thing 

 which Ave have found really efficaceous ; the foliage was not injured and the caterpillars 

 were killed. In autumn, when the operation of sticky-banding the trees was carried 

 on as usual, the lesser quantity of wingless moths captured was very remarkable. 

 Up to date of report nine moths on one tree was the largest number captured, against 

 500 previously." On the whole, this treatment was most successful, and there is little 

 doubt that it will soon be universally used in England.
