Poultry pests (Affr. Gaz. New South Wales, 11 {1900), No. 3, pp. 2 13-220) .—EnQi 

 notes on the gapewonn, Hetemkis papiilom, H. hifle.ra, diphtiieritic roup, and a 

 number of fleas, lice, and mites which infest poultry. 



Favus in poultry, F. V. Theobald {Jour. Bd. Agr. [Loudon], 7 {1900), No. 1, 

 pp. 17-19). — A brief account of the etiology, symptoms, and treatment of this disease. 



An infectious disease of ostriches, Makx {Ceiithl. Bakt. u. Par., 1. Abt., 27 

 ■ {1900), No. 24, pp. SJ..'-824). — The author gives the details of the appearance of a 

 bacterial organism found in the blood of ostriches suffering from an apparently new 

 infectious disease. Experiments with this organism showed that it was not espe- 

 cially virulent for pigeons, but that small birds and mice were very susceptible to its 

 action. Small birds contracted the disease when fed pure cultures of the micro- 

 organism. 



AGRICULTURAL ENGINEERING. 



Irrigation and the associations syndicales, A. Chavard {Ann. 

 Agr'on.^ 26 {1900), JTo. 7, pjj. o32-3Jf.Ii). — This paper discusses the 

 importance of irrigation, especially in the south of France, and recom- 

 mends that the construction of reservoirs and canals and the division 

 and distribution of water be placed in the hands of the agricultural 

 syndicates which are organized in ditierent parts of France mainly for 

 the purpose of the cooperative purchase of fertilizers, seeds, agricul- 

 tural implements, and occasionally for insurance against losses from 

 hail and from the death of stock. An instance of such management, 

 which has been attended with highly satisfactory results, is cited in 

 detail. 



Observations on Chavard's paper, P. P. Deherain {Ann. Agron., 

 26 {1900) y jVo. 7, 2^P' 3Ji,Ji,-3If.7). — In this note attention is called to the 

 fact that France already has 22 large irrigation canals, many of which 

 are very old, constructed at great cost and requiring 1,200,000 francs 

 annualh' for their maintenance. These canals are capable of irrigating 

 254,641 hectares, but of this irrigable area only 51,122 hectares is 

 actually irrigated. In other words, only one-fifth of the water sup- 

 plied by the canals is used. While admitting, therefore, the impor- 

 tance of increased provision for irrigation in many localities, the author 

 suggests that more efforts should be directed toward disseminating 

 information regarding the need and profits of irrigation. 



Experiments in grinding Tvith small steel feed mills, F. H. King 

 {Wisconsin Sta. Bui. 82,2>P- ^'^ififj^- ^4)- — This bulletin records the 

 resttlts of something over 400 tests "to determine the rate at which 

 feed for stock on the farm may be ground with several of the types of 

 small steel mills now on the market; the power required to run them, 

 and the approximate cost of grinding." The following mills were 

 tested: (1) The O Aermotor grinder, used only with the 12-foot geared 

 Aermotor windmill; (2) the N Aermotor grinder, designed for use 

 with the 16-foot geared Aermotor windmill; (3) the No. 3 Appleton 

 Prize Pulley Mill; (4) the No. 2 Bowsher: (5) the Giant; (6) No. Ideal; 

 (7) the No. 6 Smalley Monarch; and (8) the Yessot Little Champion.
