884 EXPERIMENT STATION RECORD. 



the first 6 weeks of the test. During the last 6 weeks only one lot received grain. 

 The results were considered as showing practically no difference in the yield of milk 

 due to feeding grain to cows on good pasture. 



The relative values of mangels and swedes as food for dairy cattle, W. P. 

 J. Allsehkook {.Tiiur. British Dn'inj Fannerx' A.ssoc, Jo (lUOO), No. -i, pp. 163-168). — 

 A study of the relative cost of production, feeding value, and value of the residue. 

 Tables of analyses are compiled. From most points of view the mangel is consid- 

 ered the more valuable crop to the dairy farmer. 



The use of the cactus Opuntia ficus indica in a ration for milch cows in 

 Sardinia, G. Sotgia {Siaz. Sper. Agr. Ital., 33 {1900), j). 113; abs. in C'entbl. Agr. Chem., 

 i^9 {1900), No. 12, pp. 803, 804) ■ — An analysis showing the feeding value of the plant 

 is given and the results of its use as a part of a ration for milch cows are reported. 



The effect of gestation in cows upon the mineral matter of milk, especially 

 phosphoric acid and lime, A. Kout {L'lng. .l;/r. (Stmhloux, 9 {1899), pp. 4''jS-475; 

 abs. Ceittbl. Agr. Chem., 29 {1900), No. 10, pp. 667, 668).— It was found that the per- 

 centage of phosphoric acid and lime decreased more or less regularly up to the time 

 of calving, while the colostrum was rich in ash. When lactation was greatest the 

 percentage of phosi^horic acid and lime was lowest, the amount increasing and 

 remaining at the normal up to the middle portion of the next gestation period. The 

 food had no influence upon either the mineral content of the milk or of the urine 

 of cows. 



The handling of milk samples, M. Siegfeld {Moll:. Ztg., 14 {1900), No. 46, 

 pp. 797-799). — Rules for taking and keeping milk samples are given. 



Bacteriology of milk, B. TI. Stoxe {Amer. Chcesemakcr, 1.5 (1901), No. 179, 

 pp. 1, 2). — A i^aper read at the Vermont Dairymen's Association by the State 

 bacteriologist. 



Improvements in cream testing, A. C. Bebee {Chicago Dairy Produce, 7 {1901), 

 No. 71, p. 22). — Conclusions reached by daily experiments long conducted, upon the 

 influence of speed, temperature, and time whirled and the scaling and marking of 

 bottles in the Babcock test. 



Tyrogen, a pure culture of ripening bacteria of Emmenthaler cheese, W. 

 AViNKLER {Molk: Ztg., 14 {1900), No. 47, pp. 817, 818).— A pure culture of Bacillm 

 nobilis. The advantages in using a pure culture of this bacillus are said to be 

 improvement in the form and construction of the cheese, the imparting of a uniform 

 Enmienthaler taste and aroma, and the shortening of the process of manufacture. 



The use of the acidimeter in cheese making, Marg.\ret Knowles {Jour. 

 British Dairy Farmers' Assoc, 15 {1900), No. 1, pp. 37-40). — A popular article 

 describing the method or making the acid test of milk, and stating its advantages 

 over the rennet and hot-iron tests. 



VETERINARY SCIENCE AND PRACTICE. 



Communications from the ofEicial veterinary sanitary reports 

 for the year 1898, J. Essp:r and W. Schutz {Arch. If7.s.s. v. PraJd. 

 TIderh., '26 {1900), 2^js. 4-5, j)p. 336-388).— In one localit}- a number 

 of outbreaks of anthrax occurred after eating beet chips. The beets 

 had been grown in a territory known to be infected with anthrax. In 

 another locality several head of cattle were affected with anthrax after 

 feeding with green corn which liad been grown in an anthrax territory. 

 Outbreaks of anthrax were also caused b}' dusting stalls with soil taken 

 from the vicinity of anthrax carcasses, and using gravel from a similar
