The dairy produce act of Queensland, 1904. — Instruction to dairymen, 

 (i. S. Thomson {Queensland Agr. Jour., 15 (1905), Nos. 7, pp. 826-882; 8, pp. 879 

 887, pis. 15, fig. /). -The chief provisions of this law are noted and instructions are 

 given on milking and <>n the handling of milk and cream with a view of enabling 

 dairymen to comply with the requirements of the act. Some experiments on aera- 

 tion ami cooling are briefly reported. Numerous illustrations are given of plate cul- 

 tures inoculated in various ways. 



Cleanliness in dairy management, J. F. Blackshaw (Jour. Bd. Agr. [London], 

 1 .' i 1905), X". 8, />/>. 186-144, figs. 6). — The importance of cleanliness in dairying is 

 emphasized in this discussion and illustrations from photographs are given showing 

 the appearance of plates exposed in badly ventilated and well ventilated stables, 

 exposed under dirty and clean cows, and inoculated with milk drawn into dirty and 

 clean pails. 



Experiments with dairy cows, J. II. (tkisdale (Canada Expt. Farms Rpts. 1904, 

 />/>. 54-61) . — Tabulated data are given for several feeding experiments. 



A ration containing mangels was practically no better for milk production than 

 one containing about the same quantity of silage hut was more expensive. The 

 results of a comparison of dry and succulent forage showed the greater value of the 

 latter in maintaining the yield of milk. Comparative tests were also made of silage, 

 BQgar beets, sugar mangels, and turnips. The turnips were more expensive than 

 the other feeding stuffs and not so effective. They also imparted a had flavor to the 

 butter, rendering it quite unsalable. The best results so far as the yield of milk was 

 concerned were obtained by the sugar beets. 



Feeding cows twice a day was found as effective as feeding three times a day. A 

 test was made of the feeding value of refuse apples for cows. From the data obtained 

 it i- estimated that the apples were worth *L\40 per ton or about 7 cts. per bushel as 

 compared with roots and silage at $2 per ton. The cows seemed to relish the apples 

 and made considerable gains in live weight. 



Dairy herd records, .1. II. Grisdale, R. Robertson, and S. A. Bedford ( Canada 

 Expt. Farm* Rpts. 1904, /'i>- 47-54, 889, 840, 890). — Records are given of 28 cows of 

 different breeds at the Central Experimental Farm, 21 cows at the Experimental Farm 

 for the Maritime Provinces, and of 7 cows at the Experimental Farm for Manitoba. 

 Notes are also given on the feeding of the cows at the 2 farms first mentioned. 



Tests of Guernsey cows for advanced registry ( < bnm <ti<-ut Stat,- Sta. lij>t. 1904, 

 l>t. ■',, /K -fi;ii). — Yearly tests of 15 cows admitted to advanced registry are reported. 

 Tests of 2 other COWS are also noted. 



Experiments in aseptic milking-, V. WlLLBM and A. Mifi.k (Rev. Gen. Lait, 4 

 [1906), No. 18, pp. 409-419). — In the series of 35 experiments here reported, great 

 precautions were taken to prevent the contamination of milk during milking. The
