134 INJURIOUS INSKCTS OF 1903. 



It will be remembered thai we had very bad weather just be- 

 fore and just after September 15th, and it was impossible to get 

 into the nurseries for work at that time, hence the last few nur- 

 series were inspected immediatel\' after that date. Furthermore, 

 as an accommodation, the following nurseries were inspected late 

 in the season, the owners claiming that they were either away or 

 unaware of the time limit set by the law :

 small Green Tree Hopper, Empoasca mali, Osborn, which has been 

 extremely prevalent in many of the nurseries, causing the leaves 

 to curl and checking the growth of the trees. This is a difficult 

 pest to combat and calls for some experimental work on the part 

 of the Entomologist next summer. As usual. Fire Blight was 

 found in many of the orchards, but all nurserymen and orchard- 

 ists appear to know the way to check that by proper pruning. 



In connection with Plant Lice the following suggestions may 

 be of use to nurserymen. As is well known, the lice are so
