pillars was noticed, and in some places they seriously injured 

 the appearance of the trees. Plant lice of various kinds were 

 also much in evidence ; and many specimens of tussock moths, 

 particularly the old tussock moth, were sent to the station for 

 identification. Many inquiries about cutworms were re- 

 ceived, but the correspondence on this topic was less than 

 during the two years preceding; while inquiries about wire 

 worms and the best treatment for them were more abundant 

 than usual. In greenhouses the white fly is a serious pest, 

 causing the loss of thousands of dollars, and much corre- 

 spondence ; while thrips, which was so much in evidence a 

 few years ago, was inquired about but twice. The asj)aragus 

 root miner, an insect not hitherto reported in this State, has 

 made its appearance in several places in sufficient abundance 

 to cause considerable injury. But little is known of the life 

 history of this insect, and further investigations uj)on it are 

 planned for the coming season. 



As a whole, the important insects this year have been of 

 so many different kinds that it has been impossible to give to 

 most of them the uninterrupted attention which is needed, 

 even for our most abundant forms, in order to test the best 

 methods of control. There is no insect known about which 

 more information would not be of assistance in leading to 

 the discovery of better remedies than we now have ; and it 

 is most desirable that the insects causing the most loss in 

 any year shall be carefully studied at the time, in the hope of 

 finding better methods of control. Such conditions as have 

 prevailed during the past season, therefore, where work of 

 this kind has been almost impossible on account of so many 

 calls for information in different directions, produce a year 

 which must be considered as more or less unsatisfactory in the 

 way of results ; and this was certainly the case in 1906.
