California may justify this j)essimistic view; but the horticultural aud 

 agricultural press should encourage rather than 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 hast}^ expression of opinion on the part of the individual editor 

 convince one or two persons critically situated that it is not worthwhile 

 to attempt to stamp this pest out, it is quite within the bounds of i)os- 

 sibilitythat 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 x)est was apparently limited in this country to a small area. 

 Immediate 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 Bakerslield to take at once in hand, audit was 

 important that every individual potato-grower 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 

 fact the necessity, of stringent local laws and their thorough enforce- 

 ment. 



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

 Oregon Agricultural ExiDeriment Station, published April 1893, Mr. 

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

 with the Codling Moth and the Hop Louse. Experiments in spray- 

 ing agamst the former pest were conducted with flour paste and Paris 

 greeu, 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 eiflcacy. Mr. Washburn finds 

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

 interesting table of dates of transformations. The proper time for the 

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

 Under the head of 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 oi)inion exi^ressed 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- 

 mended is a solution of soap and tobacco, which is much cheaper than 

 the quassia mixtures and less dangerous than the kerosene emulsion 

 while almost equally efficacious. 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
