pillars was noticed, and in sonic places they serionsly injured 

 the appearance of the trees. JMant lice of varions kinds were 

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

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

 identiticatiou. Many in<iuiries about cutworms were re- 

 ceived, bnt the corresj)ondence on this topic was less than 

 dnring the two years preceding; while inquiries about wire 

 worms and the best treatment for them were more abimdant 

 than nsual. In gnnndiouses the white fly is a serious pest, 

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

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

 few years ago, was inquired about l)ut twice. The asparagus 

 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 \\n) life 

 history of this insect, and further investigations upon it are 

 fdanned 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 iminterrupted attention wliich 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 nmst be considered as more or less unsatisfactory in the 

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