Cnlitbi-nia in;iy justify this pessimistic view; but the horticultmal and 

 ajiiicultuial press should encourage rather tluin discourage all attempts 

 to lighten the burden of the farmer. It is faulty logic to argue that 

 because a thing has not been well done it can not be well done. Should 

 this hasty expression of oi)inion on the part of the individual editor 

 convince one or two ])ersons critically situated that it is not worth while 

 to attempt to stamp this pest out, it is quite within the bounds of pos 

 sibility that an irreparable harm may be done to the entire potato-grow- 

 ing interests of the country. At the time of publication of our article 

 this new i)est was apparently limited in this country to a small area. 

 IranuMliate energetic efforts would have at least retarded its spread and 

 might have brought about its practical extinction. It was a matter for 

 the town corporation of Bakersfield to take at once in hand, ajudit was 

 important that every individual potato-groM er in that neighborhood 

 should at once do his best to destroy the insect. The carelessness or 

 indifference of one, however, would vitiate to some extent the well 

 meant and energetic efforts of many. Hence arises the desirability-, in 

 iact the necessity, of stringent local laws and their thoiough enforce- 

 ment. 



The Codling Moth and Hop Louse in Oregon.— In Bulletin 25, of the 

 Oregon Agricultural Experiment Station, published April 1893, Mr, 

 F. L. Washburn publivShes a short report of his work during 1892 

 with the Codling Moth and the ITo]) Louse. Kxperiments in spray- 

 ing against the former pest were conducted with tlour paste and Pai-is 

 green, Paris green alone, I. X. L. and soap, I. X. L., Paris green, and 

 soap. The flour paste mixture was found unsatisfactory, while the 

 others were of a reasonable degree of efficacy. Mr. Washburn finds 

 that the Codling Moth has three broods in Oregon, and publishes an 

 interesting table of dates of transformations. The proi)er time for the 

 first spraying in an average season in Oregon is the first week in June, 

 ruder the head c.f the "Hop Louse" the author concludes that kero- 

 sene emulsion is not a safe insecticide in the hands of the Oregon hop 

 growers. This is contrary to the opinion expressed by the same author 

 a year ago, and is based upon the fact that the average grower fails to 

 make the mixture properly. A remedy which is unhesitatingly recom- 

 mende<l is a solution of soap and tobacco, which is much cheaper than 

 the (piassia niixtares and less dangerous than the kerosene emulsion 

 while almost equally efiticacious. It may be well to mention in this con- 

 nection that Mr. Koebele, one of the California agents of this Division, 

 was sent to Oregon and Washington in May for the purpose of demon- 

 strating the ease with which a satisfactory emulsion maybe made, and 

 of giving a practical illustration of the methods recommended by this 

 Division for the destruction of the Hop Louse. It is as yet too soon 

 to report results, but it may be stated that, so far as his experiments
