Serum therapy in fowl cholera, Willerding {Dent. Thiemrztl. Wchnsdu:, 10 

 {190-i), Xo. 50, pp. 473, 474)- — The author conducted a number of experiments for the 

 purpose of testing the value of the Landsberg Septicidin and the fowl cholera serum 

 of Jess and Piorkowski. Neither of these sera was found to have any noticeable 

 effect in protecting healthy fowls against infection from fowl cholera or increasing 

 the resistance of birds which were ah'eady infected. 



The chicken mite, G. W. Herrick {Mija^issippi Sta. Bui. 78, pp. 1.3,fig.'<. 4). — 

 The most favorable conditions for the rapid multiplication of the chicken mite are 

 tilth and insufficient illumination of the chicken houses. The author made a number 

 of experiments in the construction of nests and roosts so that these structures could 

 be readily cleaned and illuminated. In combating the chicken mite with direct 

 remedies the author tested the value of a method which consisted in cleaning the 

 houses once every 2 weeks and dusting them with a mixture containing 3 parts of 

 air-slaked lime and 1 part sulphur. This method was quite effective, but the author 

 believes that the insecticide should be apjilied at least once per week. Good results 

 were obtained from the use of crude petroleum and kerosene. These insecticides 

 were sprayed or rubbed upon the walls of the nests and other structures in the 

 chicken houses. Kerosene was found to be as effective as crude petroleum, but its 

 effects did not persist so long, since it evaporated more rapidly. During the season 

 of the year when dust is not accessible to the hens the author recommends that 

 boxes containing road dust should be provided for them. Badly infested old chicken 

 houses of slight value may be burned and new ones constructed, or they may be dis- 

 infected by the remedies already mentioned and the use of boiling water. Poultry 

 houses should not be in connection with barns or stables, and sitting hens should 

 be isolated from the rest of the hens, so as to prevent their infestation by mites. 



The incineration in the open field of carcasses affected -w^ith anthrax, Vol- 

 MER {Brii'ni. Thieri'irztl. Wchn.'^clii-., 1902, X0.4I, pp-017,618) . — Various material has 

 been used in producing heat for the incineration of anthrax carcasses in the open 

 field, and notes are given on the comparative cost of the process according to these 

 different methods. The author recommends that the incineration be conducted 

 under the direction of officials, so that complete destruction of the carcasses may be 

 secured. 



Innocuous disposal of animal carcasses by means of burning, Lothes and 

 Profe [Birlhi. Thleri'vrztl. Wchnftchr., 1902, Xd. 37, i>p. oo7-'>60). — A detailed report 

 is given of a number of experiments which were conducted for the purj^ose of deter- 

 mining the relative effectiveness and cost of various incineration methods for destroy- 

 ing animal carcasses. It is recommended that unusual care be exercised to secure 

 the complete destructi(3n of all carcasses in cases of serious infectious diseases. 



American meat inspection, A. Zschocke ( DeuL Thierdrztl. Wchnschr., 10 (1902), 

 Nos. SI, pp. 301-304; 32, pp. 309-312) . — Attention is called briefly to meat inspection 

 in this country as conducted under the auspices of city, State, and national authority. 

 Detailed notes are given on the method of inspecting meat under the orders of the 

 Bureau of Animal Industry, and on veterinary police work, transportation of 

 animals, and other functions of this Bureau. 



TECHNOLOGY. 



A study of cider making in France, Germany, and England, with com- 

 ments and comparisons on American work, AV. B. Alwood ( U. S. Dept. Agr., 

 Bureau of Chemisir)/ Bui. 71, pp. II4, pis. 7, figs. 26). — The author visited some of 

 the more important cider-making districts in France, Germany, and England, and 

 describes the methods observed in those countries in the manufacture of cider. 

 Factories are described in some instances as well as the machinery used, and the 

 methods of harvesting the fruit, handling the must, fermenting, clarifying, etc.
