that all cattle in this section fattened very rapidly, became slug- 

 gish and many cases of edematous nephritis developed. This 

 condition in itself was of little importance, as it was observed 

 only on the killing floors, and it seems probable that the simul- 

 taneous appearance of hemorrhagic septicemia may be directly 

 traced to the resulting lack of vitality and power of resistance. 

 Only the fattest animals became affected, and few, if' any, recov- 

 ered. As a precaution against the disease all overfat cattle were 

 removed to poorer pastures on the leeward slope of the island, 

 where circumstances forced them to travel or go without either 

 water or feed. 



With the ripening of the pastures both the nephritis and the 

 hemorrhagic septicemia disappeared, and the question of vaccinat- 

 ing was postponed until future developments may warrant its em- 

 ployment. 



Bovine Tuberculosis Control. The annual testing of dairy 

 stock for tuberculosis on the island of Oahu, was finished with a 

 grand total of more than 7,000 tests, 216 of which gave positive 

 results. This means about 3 per cent, of reactors or apparently 

 an increase of one per cent, over last year's results, a condition 

 which would be very discouraging were it not for the fact that not 

 less than 45 reactors were encountered in herds tested this year 

 for the first time, in other words in herds that, strictly speaking, 

 cannot be called dairy cattle but from which milch cows are 

 drawn from time to time. If these herds, comprising 672 head 

 with nearly 7 per cent, of reactors, were deducted from the grand 

 total, the percentage of reactors in general would be reduced to 

 2.7. When to this is added that 50 reactors were found in two 

 dairies where no testing had been done for sixteen months, and 

 where the disease, consequently, had spread rapidly, it will be 

 found that taken all together there is a decided improvement in 

 the bovine tuberculosis situation in the City and County of Hono- 

 lulu. With the slaughter or segregation of all the reactors, and 

 with the thorough disinfection of all the premises where reactors 

 have been found, it may safely be claimed that at least 90 per 

 cent, of the local dairies are now, at the end of 1915, free from 

 tubercular infection. 



Equally satisfactory conditions can be reported from the other 

 islands where the new sanitary code of the Territorial Board of 

 Health has supplied the long needed authority for a vigorous cam- 

 paign against this disease. The three deputy territorial veteri- 

 narians are now cooperating with the representatives of the said 

 board in their respective districts and no territorial dairy permit 

 is issued until a certificate of tuberculin test has been issued by 

 one of the deputies of this board, and the reacting animals re- 

 moved. Under these conditions the complete eradication of bovine 

 tuberculosis will require only the cooperation of the owners of the 

 few remaining herds where the infection still persists in order
