The danger in the use of arsenicals as insecticides, Mestkkzat {Jour. 

 I'Iki.'hi. ct (him.. (!. scr., 2S (IHOS), Xo. 0, pp. ,i!i.l-.i<n ) . — After considering the 

 results of analyses the author concludes that there is comparatively little danger 

 from the use in viticulture of arsenical insecticides either in their api)Iication 

 or in the consuniiition of the whie. The real and sole danger is in their siniul- 

 laneous stora.ue with other substances frequently used in aiiriculturc, wliich 

 resemble them so closely that they are easily mistaken. 



Miscellaneous papers on apiculture. A brief survey of Hawaiian bee keep- 

 ing', K. 1". Phillips ( ?/ . K. Dcpt. A(ir., liiir. Ent. liul. 7.7. pt. J, pp. .'iS—oH. pJx. 

 li). — The author here reports an investigation made <»f the bee keeping industry 

 in the Hawaiian Islands. While it is stated that the business can never become 

 a leading industry it is believed that there is room for considerable expansion. 

 An active and efficient bee keejiers' association is said to have been in existence 

 for 2 years. At the present time bee keeping is largely in the hands of 4 corpo- 

 rations, they owning and ojierating at least four-fifths of all the bees on the 

 islands. 



The numi»er of colonies is estimatetl at 20,(t(H) and the output of honey for 

 1908 as 1,000 tons. Most of the honey is shipped to the mainland or Europe. 

 .V list of honey i)lants furnished by 1). li. A'an Dine is i)resented. The intro- 

 duced algeroba tree (Prosopis juHfloru), which is the same or closely related 

 to the mesquite of the Southwest is said to be one of the most important. 



Two-thirds of the honey shipi)ed annually from the islands is largely or 

 entirely honeydew h(mey (E. S. R., li), p. 1059; 20, p. 261). The greater part 

 of this comes from the exudation of the sugar-cane leaf-hopper {Perkinsiclhi 

 .'<(icch(irici<l(i). but possibly some of it from the sugar-cane aphis (Aphi.'i 

 .fnccJuiri). 



As Hawaiian honey sells for low prices the bee keepers of the islands are 

 desirous of producing wax instead. A method suggested by the author is de- 

 scribed whereby wax secreticm is stimulated by shaking the colonies on starters 

 of foundation, the manipulation being identical with the shaking in ti'eating 

 for bee disease. 



Careful examinations were made of aiiiaries in the islands but no trace of 

 disejise was found. IJegulations have recently been passed which place restric- 

 tions on the importation of honey bees and honey. 



Miscellaneous papers on apiculture. The status of apiculture in the 

 United States, E. F. riiiLLii's ( L'. /S'. Dcpt. Agi:, Bur. Ent. Bui. 75, pt. 6", pp. 

 "I'.t-HO). — A discussion of the subject in which the notable gi'owth of apiculture 

 (luring the past half century is pointed out. It is stated that there are in the 

 Inited States over 700,000 bee keepers producing annually i(;20,000.000 worth of 

 honey and .$2,000,000 worth of beeswax, and that the annual imi)ortation of 

 honey amounts to about 2,r»00.000 lbs., and that of wax to about 7(M>.000 lbs. 

 other tojtics discus.sed include the inipoi'tance to American agriculture of the 

 honey bee as a polleni/ing agent, the present sources of loss in bee keei)ing due 

 to swarming, winter losses, enennes, disease and waste of wax and nectar, and 

 (he need of furtlier investigations in apiculture.
