908 EXPERIMENT STATION RECORD. 



removed from 55 to 60 per cent of the juice. The highest extraction, approxi- 

 mately 75 per cent, was secured with a 5-roller mill. In an earlier bulletin of 

 the station a form of sulphuring apparatus was described (E. S. EL, 7, p. 719). 

 In the present bulletin a still simpler form improvised from a large sirup bar- 

 rel is described. The station has also found it possible to employ liquified 

 sulphurous acid as a clarifying agent. While good results may be obtained 

 by the use of sulphur fumes alone it was found that better results could be 

 obtained by the use of lime in addition. 



Instead of either of these methods, however, the bisulphite of lime may be 

 used in the proportion of 1:200, although the sirup is not usually so bright as 

 when the juice is treated with sulphur fumes. It is stated that in many cases 

 the acid phosphate of lime was used as a clarifying agent with excellent 

 results. Fairly good results were obtained by the use of sand filters for the 

 removal of suspended matter. The use of cotton batting as a filter for the hot 

 sirup was tested, favorable results being secured. Numerous other features 

 connected with the manufacture of cane sirup were also studied experimentally.

VETERINARY MEDICINE. 



Division of veterinary science, J. A. Gilruth (New Zeal. Dept. Agr. Ann. 

 Rpt.,13 (1905), pp. 152-227, figs. 3). — A detailed report is made of the veterinary 

 staff of New Zealand, the work performed in meat inspection in connection with 

 abattoirs and export slaughter houses, dairy inspection, and various investiga- 

 tions relating to animal diseases. 



Contagious mammitis has spread without much control since the author's 

 previous report. It is recommended that compulsory notification be required 

 for this disease together with the registration of all dairy herds, their periodic 

 inspection, and the sterilization and pasteurization of all milk at creameries. 

 The present distribution of the disease is briefly outlined. In treating mammitis 

 the author recommends injections of boracic acid. Notes are also given on the 

 present occurrence of blackleg in New Zealand. By means of preventive 

 vaccination the mortality of this disease has been reduced to the extent of 75 

 per cent. 



A brief account is also given of anthrax, hepatic cirrhosis, tuberculosis, abor- 

 tion, sterility, contagious pleuro-pneumonia in lambs, a disease resembling 

 braxy, cystic kidney in pigs, cancer of the eyelid and liver in fowls, hydatids 

 in sheep, tetanus, various forms of cancer in calves, and pasteurellosis in calves 

 and pigs. A study of the last-named disease showed that the cause was a 

 micro-organism belonging to the Pasteurella group, which produces a hemor- 

 rhagic septicemia. The organism appears to gain entrance through the navel
