as the main part of the enclosure remains unchanged ; that is, the 

 original beach sand through which all excretions likely to con- 

 taminate the kennels may percolate to the tide water below. (2) 

 The horse and mule section has now been completely rebuilt, the 

 number of posts in the fences being almost doubled, so that the 

 distance between them in no case exceeds eight feet. The sta- 

 bility has also been greatly increased by connecting all the posts 

 with a 2"x4" stringer spiked to the top. This will prevent the 

 animals from "riding" on the fence and will thereby double the 

 life of the enclosures. All gates have been reinforced and re- 

 hung and a mixture of oil and sand applied to all woodwork ex- 

 posed to the teeth of the animals. 



A small chamber 9'xl2' has been added to the office so that 

 the keeper may have a place to sleep and keep his clothes, for 

 which purpose the office has hitherto had to serve. 



HILO QUARANTINE STATION. 



Dr. Elliot reports progress with the construction of this station, 

 though the contractor has had trouble with his laborers. He 

 seems, however, to be satisfied with the work so far as it has 

 gone, and expects the station to be finished by the latter part of 

 July. He further recommends that the keeper, when he secures 

 one, be provided with some tools — spade, shovel, pick, wheelbar- 

 row, etc. — so that he can put him to work gathering rock for the 

 road and stable floors. 



HOG CHOLERA. 



As previously reported, this disease has spread to a consider- 

 able extent and many animals have died. The method of con- 

 trol now in vogue in the States — the injection, subcutaneously, of 

 blood serum obtained from hogs which have been hyperminimized 

 against the disease — has been applied here and with seeming suc- 

 cess ; in fact, with highly satisfactory results. It may, for in- 

 stance, be mentioned that in one herd of 20 to 40 animals of all 

 sizes, and all of which were afifected with the disease, some to 

 such an extent that they could not walk, practically every one 

 which was inoculated has either recovered or else improved, while 

 two, which escaped inoculation by breaking through the fence, 

 developed the disease and one of them has died, wdiile none of the 

 treated hogs have been lost. 



The establishment of a serum institute for the manufacture of 

 hog cholera serum here has been considered in view of the price 

 asked for the commercial serum, which amounts to from two to 

 three dollars for full-grown hogs. There is, however, consider- 

 able danger of spreading or perpetuating the disease here, as it is 

 necessary to keep on hand animals infected with the most virulent
