456 EXPERIMENT STATION RECORD. 



Tlie practical work done in Colorado in combatinfi the Howard scale was dis- 

 cussed by E. P. Taylor (pp. 87-93). Good results were obtained from the use 

 of lime-sulphur mixture and other insecticides. F. M. Webster discussed the 

 value of parasites in the control of the insect enemies of cereals and forage 

 crops (pp. 94-100). In this paper particular attention was given to wheat 

 midge, Hessian fly, .iointworms, and army worm. 



A paper on the insect enemies of tobacco in Florida was discussed by W. A. 

 Hooker (pp. 106-111), special mention being made of bud worms, tobacco worms, 

 tobacco flea-beetle, grasshoppers, tobacco leaf-miner, cutworms, and leaf hoppers. 

 E. D. Sanderson presented suggestions regarding the construction of a spray 

 nozzle which will give definite proportions of a mechanical mixture of oil and 

 water (pp. 112-116). 



The other papers presented at the meetings included one on GastropMlus 

 nctsaJis and Ccratopogou eriophorus and insects in relation to leprosy, by C. F. 

 Baker (pp. 117-119). On the Eradication of the Black-Currant Gall-Mite, by 

 W. E. Collinge (pp. 119-123; and the destruction of mosquitoes in houses by 

 means of chrysanthemum, by A. L. Herrera (pp. 123, 124). 



Report of the meeting of inspectors of apiaries (San Antonio, Tex., 

 November 12,) 1906 (C7. *S*. Dcpt. Ayr., Bur. Eitt. Bui. 10, pp. 79, pi. i).— At 

 a meeting of inspectors of apiaries in San Antonio, Texas, November 12, 1906, 

 a number of papers were read, which have been collected in the present bulletin. 



The Bacteriology of Bee Diseases was discussed by G. F. AVhite (pp. 10-18). 

 The speaker recognized 3 infectious bee diseases — European foul brood, Ameri- 

 can foul brood, and pickle brood. 



E. F. Phillips referred to The Present Status of the Investigation of Bee 

 Diseases. A historical account of the subject was given and detailed notes 

 were presented on the growth and behavior of Bacillus alvci, B. A., and B. larvw. 



Apiary inspection in New York was considered byV3. Stewart. An inspector 

 must be a practical bee raiser. No bees are strictly immune to disease, but 

 vigorous Italians are nearly so. 



F. A. Parker spoke of American Foul Brood on the Pacific Coast. In Cali- 

 fornia the disease behaves somewhat differently than in other parts of the 

 country. Some bee raisers have as many as 4,000 swarms. The disease spreads 

 rapidly in many cases. Much careful attention is requii-ed on the part of the 

 Inspectors to prevent disaster. 



N. E. France outlined the history of bee inspection in Wisconsin, referring 

 particularly to the difficulties met by the inspector in carrying out the State 

 law. 



Practical bee keeping, R. Benton {Montana Sta. Bui. 67, pp. 75, pis. .{, figs. 

 15). ■ — A sunmiary is given of information important to the beginner and small 

 apiarist. The bulletin is based on available data and experiments in Montana. 

 The subject-matter includes the structure, habits, and varieties of the honey 

 bee, and a discussion of honey plants, beehives, handling of bees, starting an 

 apiary, wintering bees, queen rearing, control of swarming, production of honey, 

 and diseases of bees. 



Bee culture, I. Hopkins (.Vr/r Zeal. Dept. Agi:, Dirs. Biol, and Hort. Bui. 

 IS, pp. 3-'i, figs. 2'i). — Practical directions are given regarding the care and 

 management of bees, including the location of the apiary, hives, and other bee 

 apparatus, honey plants, etc. A special section of the bulletin is devoted to a 

 discussion of the relation of bees to flowers and fruit growing. 



The cause of American foul brood, G. F. White (U. 8. Dept. Agr., Bur. Ent. 

 Circ. 9^. pp. .'/)• — The author had previously announced the occurrence of 

 Bacillus larva: in American foul brood. In experiments reported iu this circu- 

 lar the disease was transmitted to healthy colonies of bees by material from
