and arsenate of lead gave a decided superiority for the latter. The author 

 properly emphasizes the necessity of very thorough application if satisfactory 

 results are to be secured. This bulletin is well illustrated and printed on 

 excellent paper. 



Insect Enemies of Tobacco, by Z. T. Metcalf, N. C. Dep't. Agric. 

 Special Bui. p. 1-72, 1909. 



This publication discusses first the general forms of injury, the methods of 

 control and the insecticides available for use. The author concludes from vari- 

 ous estimates that there is no danger to the users of the product from apply- 

 ing arsenates to tobacco, though he does not advise such treatment shortly 

 before harvesting. There is a brief discussion of insect structure and classi- 

 fication. Numerous forms are treated in a summary manner, the author 

 making the bulletin of greater practical value by distinguishing bets\'een the 

 principal and the lesser insect enemies. The publication is profusely illus- 

 trated, the appearance of many figures, however, being seriously marred by 

 the poor quality of the paper. 



Fumigation of Apples for the San Jose Scale, by A. L. Quain- 

 TANCE, U. S. Dep't. Agric, Bur. Ent. Bui. 84, p. 1-43, 1909. 



This bulletin gives in detail methods employed and results secured in 

 fumigating fruit infested with San Jose scale. The author has demonstrated 

 the practicability of such treatment and suggests the desirability of its adop- 

 tion in case the countries now prohibiting the importation of fruit infested 

 by San Jose scale will accept such fruit. He also calls attention to the ap- 

 plicability of this treatment to other fruits. The bulletin is illustrated by 

 two admirably colored plates, and is made more valuable by an appendix 

 giving a synopsis of the laws and decrees relating to the introduction of live 

 plants and fresh fruits in force in foreign countries, and similar laws and 

 regulations of the various American states. 



Bee Keeping in Massachusetts, by Burton N. Gates, U. S. Dep't. 

 Agric, Bur. Ent. Bui. 75, Part 7, p. 81-109, 1909. 



This very readable publication gives a historical sketch of bee keeping in 

 Massachusetts, together with a large amount of interesting local information. 

 There is an annotated list of the more important honey-producing plants, 

 together with local observations on the nectar-producing period in represent- 

 ative regions. Data is given upon the employment of bees in greenhouses. 

 One of the curious results of the investigation is the evidence gathered 

 showing serious injury here and there to the bee keeping industry by the 

 superabundance of gypsy and brown-tail moth caterpillars. This bulletin 

 should be most serviceable to all bee keepers in New England, particularly 

 as it gives a bibliography of the more important articles relating to bee 

 keeping in Massachusetts.
