REPORT OF ASSISTANT VETERINARIAN. 



Honolulu, Oct. 31, 1912. 



Dr. V. A. Xorgaard, Chief of Division of Animal Industry, 

 Bureau of Agriculture and Forestry, Honolulu, T. H. 



Sir : — I beg to submit herewith a report for the month of 

 October : 



1 iibcrculosis Control. 



The following animals were subjected to the intra-dermal test: 



T. P. C. 



October 7-10 — Mrs. Andrews 1 1 



9_12_Bernal Live Stock Co 12 10 2 



10-12— A. Waterhouse 5 5 



16-19— F. C. Atherton 1 1 



19 16 3 



Although the number examined is small it contains points of 

 considerable interest. The animals tested for the Bernal Live 

 Stock Company came from Kona and were purchased from the 

 Gouveira Ranch, which supplies different dairies on this island 

 with a good many milch cows. Out of two hundred (200) head 

 of cattle arriving here from Kona ten (10) have been condemned 

 on the test which, if this can be taken as any criterion, would 

 show 5% of tuberculosis among the dairy animals in Kona, Ha- 

 waii. This further means that with every hundred head of cattle 

 shipped in here from Kona there are five tuberculous animals to 

 become centers of infection. 



This clearly demonstrates the value of eternal vigilance in the 

 campaign against tuberculosis and the great value of a milk ordi- 

 nance, such as we have, which requires that every dairy supplying 

 milk for human consumption must be composed of animals free 

 from tuberculosis, in other words animals which have success- 

 fully passed the tuberculin test. 



By keeping careful watch over the dairies we have been able to 

 eliminate ten centers of infection which have been imported 

 directly from the island of Hawaii. Had these ten animals gone 

 untested they would have rapidly spread the disease either directly 

 or indirectly to every dairy on the island of Oahu, and the labor of 

 years would have been lost and conditions would have rapidly 

 reverted to what they were when systematic testing was first 

 established. 



Dairy stock shipped from the other islands are purchased by 

 dairymen here subject to the test so the condemnation of these 

 animals entails no loss to them as other animals are sent to take 

 their places. It has been the natural tendency on the part of the
