with it receive little or no benefit from vaccination which accounts for the 

 deaths reported among the recently vaccinated cattle. 



It is my opinion that the poorly nourished condition of the majority of the 

 cattle in this district is mainly contributing to the large number of deaths 

 so far reported since the commencement of the outbreak. At present they 

 are physically unable to resist any infection even of a comparatively mild 

 character. It is entirely probable that as much loss is occuring from the 

 effects of the drought as there is from the disease. 



EXPERIMENTAL WORK. 



A small experiment was started in an attempt to demonstrate the presence 

 or absence of hog cholera on the island of Kauai. 



A sample of blood was sent to the laboratory from a case declared by Dr. 

 Golding to be '' typical hog cholera." This sample, which arrived in good 

 condition, we had filtered at the Tripler General Hospital, Fort Shafter and 

 the filtrate was used in the inoculation experiments. 



On February 19, two young hogs of known susceptibility were injected 

 with varying amounts of the filtered blood. Three to five times the usual 

 amounts were injected so to assure that each received a sufficient amount of 

 the virus if it was there. Since inoculation the pigs have shown no symptoms 

 of hog cholera and have continued to gain weight in a normal manner. 



Before any definite conclusions are reached further experiments will have 

 to be made.
