migratory species of in(»sqiiitoes from cousideratiou. During the summer of 

 I'.KtS. ilie li()us«> iiios(iuit(» {('ulr.r iiiiiiciis) was present in tlie rities in j^reat 

 numl)ers. The author ilesc'ril)es tlie life liistory and hal)its of this sjjecies 

 and the many usual and unusual places in wliieli it l)reeils. As many female 

 mosquitoes pass the winter in cellars, it is recommended that such i)laces be 

 fumi>:ated eitlier with a mixture of e(pial parts of carliolic acid crystals and 

 jium camphor (»r with Jimpson weed. In a municipal campaifiu all standing 

 water should be located and removed by filling or diaining. The standing 

 water in sewer cat<-h basins slionld be oiled frequently. 



Remedies for the San Jose scale, E. P. Taylou (U/.ssoHrt Fruit Sta. Cite. 3, 

 Pit. '/). — This circnlai- contains formulas, methods of preparation, and direc- 

 tions for the use of standard and connnercial lime-suli»lnir wasli. oil emulsion, 

 and miscible oil sprays. 



Homemade soluble oils for uce against the San Jose scale, J. L. Phillips 

 {Virginia Sta. Bui. J7!>, ii/i. 7.S-88). — The following conclusions have been 

 drawn by the author from cooperative orchard tests: 



"Homemade soluble oils are rt 'ommended for trial in place of the lime- 

 sulithnr wash, under certain conditions. Further tests nuist be aiade before 

 we can recommend them unreservedly. For general orchard spraying the lime- 

 sulphur is probably more satisfactory. 



" The various prepared or patented brands of soluble oils cost about three 

 times as much as the homemade product containing the same percentage of 

 oil. Our tests indicate that the homemade oil is as effective as the itrepared 

 t)il. The cost of the homemade oil is about the same as the cost of ]ime-suli>hur. 



" The homemade soluble oil is more practicable for the coujuiercial orchardist 

 than for the man who has only a few trees, unless one person will make the 

 material for a neighborhood. 



" It is not quite as troublesome and disagreeable to make soluble oil at home 

 as it is to make lime-sulphur. 



"Apply the soluble oil spray only in the doi'uiant season. The trees should 

 not be pruned before they are sprayed, as the oil may injure the cut surfaces, 

 unless they are painted. 



"The homemade soluble oil spray is recommended for trial against the San 

 Jose scale, and the maple scale. It is not rec<miniended for use against the 

 scurfy scale." 



Cooperative [spraying-] experiments, L. R. Taft (Michigan Sta. Rpt. 1908, 

 pp. loS-iai). — The author here discusses the general conclusions arrived at 

 as the result of spraying experiments with insecticides and fungicides. 



Spray calendar, C. E. Sanborn {Texan Sta. Bui. J 13, pp. 5-10, pi. I). — Spray- 

 ing machinery, and formulas for, preparation, and use of insecticides and 

 fungicides are briefly considered. 



Spraying calendar, L. li. Taft and R. S. Shaw {Michigan Sta. Spec. Bui. Jf5, 

 folio). — In this wall calendar, dirwtions are given for the iireparation and 

 application of insecticides and fungicides. 



Homemade oil emulsion, E. I*. Taylor {Missouri Fruit Sta. Circ. -'/, pp. 3). — 

 Directions for the preparation and use of kerosene emulsion. 



Analysis of Paris green and other insecticides, L. L. Van Slykp: {New 

 York State Sta. Rpt. 1901', pt. 3, pp. 225-227). — This is a historical review of the 

 legislation in New Yorli relative to insecticides, including the main provisions of 

 the present law, and a l»rief summary of the work of the New York State 

 Station in the analysis of insecticides. During the years lS9t) to 11)02. 130 

 samples of Paris green were analyzed, the anioimt of arsenious oxid varying from 

 55.34 to 02.87 per cent, the cojiper oxid from 20.r)3 to 31.2 per cent, the arseni- 

 ous oxid in combination with copper from 49.70 to 58.45 per cent, and the water
