For the details of the routine work of the Division, see appended 

 report of the Assistant Territorial Veterinarian. 



The number of reactors found in the Waialae Dairy, ten head, after 

 a six months' interval between tests is the lowest ever found in this 

 dairy since testing began. It is my opinion that this is due entirely to 

 the elimination of the nurse cow method of raising their calves. It has 

 been clearly demonstrated that these nurse cow^s constituted a continual 

 source of infection to the young stock through the milk. A few of 

 these heifers developed lesions of tuberculosis at eight to ten months 

 of age, but the large majority of them did not react until they were 

 from two to four years old. This great source of infection being elimi- 

 nated, eradication of tuberculosis from this dairy should be rapid. 



The live stock importations included thirty head of pure-bred regis- 

 tered Hereford bulls, consigned to Hind, Eolph & Co., for the improve- 

 ment of the cattle on Mr. Sam Wood 's ranch. Island of Hawaii. They 

 were a very uniform bunch of bulls and the finest specimens of the breed 

 imported here for some time. 



HAWAII. 



Dr. Elliot reports the importation of 6 mules and 15 head of grade 

 Holstein cows at the Port of Hilo. 



The tuberculosis control work consisted of the testing of 132 head 

 of cattle, of which number 6 were condemned. Five autopsies were 

 made on condemned cattle, and visible lesions of tuberculosis found in 

 four. 



A small outbreak of swane plague occurred among the stock of the 

 Hakalau Plantation Company, resulting in the death of 1 boar, 2 sows 

 and 6 sucklings. The outbreak was promptly checked by vaccination. 



Dr. Eowat reports the testing of 64 head of cattle, w4th no reactors. 

 Also the vaccination of 306 head of cattle for hemorrhagic septicemia. 

 Since vaccination no further deaths have occurred and the outbreak can 

 be considered checked. 



KAUAI. 



Dr. Golding reports the vaccination of 249 head of cattle, horses and 

 mules at the Hanalei Eanch and the testing of 138 head of cattle scat- 

 tered over the Island, for the month of June. 



For the month of July, the examination of 138 head of cattle, with 

 4 reactors, and the testing of 138 head of cattle in plantation camps, 

 with 2 reactors. Autopsies were held on 5 reactors, lesions of tubercu- 

 losis being found in each case.
