holes and burrows (a teaspoonful to each, with a glass syringe), which 

 are then stopped up, and a careful look-out should be kept for the 

 borer, as much in worthless trees as in those that are valuable.

Lima Bean Pod-borer, The, and Yellow-necked Flea-Beetle, 



The. By F. H. Chittenden, Sc.D. {U.S.A. Dep. Agr., Bur. Entom., 

 Bull. 82 part iii. ; Dec. 28, 1909; 1 fig.). — An interesting account of 

 (1) the Lima-bean pod-borer {Etiella zinckenella Treit.), which is the 

 larva of a gray-and-white moth with ochreous scales on the fore-wings, 

 for which no method of control has yet been discovered, and (2) the 

 yellow-necked flea-beetle (Disonycha mellicolUs Say.), which attacks 

 the leaves of beet, and the spinach flea-beetle {D. xanthomelaena 

 Dalm.). Spraying with arsenic als seems to be the only remedy for 

 these pests. — V. G. J. 



Lime-sulphur, Concentrated : Its Properties, Preparation, 

 and Use. By John p. Stewart {U.S.A. Exp. Stn. Pa., Bull. 92; 

 July 1909; 5 figs.; 6 tables). — A description of the advantages and 

 disadvantages of concentrated lime-sulphur. Its principal short- 

 comings being : extreme causticity to flesh, corrosion to machinery, 

 large amounts of sediment of uncertain value, necessity for immediate 

 apphcation, and its bad keeping qualities. The author has made a 

 careful study of the matter, with a view to reducing some of the 

 present difficulties. — V. G.J. 



Lime-sulphur Mixtures. By W. M. Scott {U.S.A. Dep. Agr., 

 Bur. PI. Ind. Circ. 27; April 1909; 2 figs.). — This paper is a report 

 of the second season's experiments with lime-sulphur preparations for 

 summer spraying, together with additional experiments with other 

 sulphur compounds. The work was carried out more thoroughly than 

 before on both the peach and the apple and extended to include the 

 cherry. The experiments resulted in some modifications in the method 

 of making the mixtures for the peach and for Japanese plums, but 

 on the whole they were very encouraging for further experiments, 

 and for widespread use in the orchard where Bordeaux mixture is 

 found objectionable (see Journal E.H.S., vol. xxxiv. p. 129).

Lime-sulphur, Preparation and Use of Concentrated. By 



John P. Stewart {U.S.A. Exp. Stn. Penn., Bull. 99; May 1910; 

 3 figs.). — According to the author the art of spraying is in a state of 

 transition, involving the breaking away from Bordeaux mixture and 

 the whole list of copper sprays which have served as fungicides for 

 more than a quarter of a century, and the substitution of what may 

 become an equal list of sulphur sprays. Among the latter, the clear, 

 concentrated lime-sulphur solution will undoubtedly occupy a leadmg 

 place.
