advisable to await the return to Honolulu of the owner of the 

 above mentioned dairy herd, when action will be taken by him 

 and other dairy men in his neighborhood, to ascertain exactly 

 what can be done in the premises. 



In the meantime the annual test is being continued with very 

 satisfactory results among which may be mentioned the fact that 

 the Mokuleia herd of 448 dairy animals, reported as injected 

 (in Dr. Case's report) gave only one single reactor and that a 

 great majority of the smaller dairies are found absolutely free 

 of the infection. 



Hog Cholera. 



The outbreak mentioned in my report for January as occurring 

 at Puuloa, and which undoubtedly was complicated with salt poi- 

 soning, if not entirely due to it, has subsided. A recent out- 

 break at Mills School, Manoa, was treated with the serum-simul- 

 taneous method, the virus being obtained from one of the sick 

 animals on the premises. The results were very satisfactory 

 and will be watched with interest in order to ascertain the length 

 of immunity conferred by this method. A more recent outbreak 

 in the Kapahulu district was treated with the serum alone, but 

 some very sick, and therefore untreated hogs were left with the 

 serum treated ones for the same purpose. 



Having read the replies received from the hog raisers to wdiom 

 copies of the proposed Rule IX were sent, it appears to me ad- 

 visable that the same be promulgated. With some slight changes 

 in the wording of the section pertaining to the quarantine of 

 infected premises, the printed rule might be made to work auto- 

 matically as an order to quarantine, when handed to the owner 

 and receipted for. This would obviate the necessity of having 

 special quarantine orders prepared and would simplify the matter 

 considerably. 



On the island of Maui a hui of hog raisers have imported 

 50,000 c.c. of hog cholera serum and placed the same in charge of 

 the deputy territorial veterinarian. Only three outbreaks oc- 

 curred there during 1915 and all were promptly checked by the 

 use of serum alone. 



The Hilo deputy was provided with 1000 c.c. of the serum 

 kept here by the Board, in order to be prepared for eventual 

 outbreaks. 



Glanders. 



This disease, undoubtedly a relic from the Waipio Valley out- 

 break in 1911, has made its appearance in Kohala, Hawaii, a 

 mare with a mule colt being reported as suffering from glanders 

 by the local veterinarian, Dr. Rowat. By direction of the Exec- 

 utive Officer, Dr. Elliot went at once from Hilo to Kohala and.
