will know from my previous reports I have long been of this 

 opinion, and have before observed gratifying results when it was 

 possible to filter the drinking water or at least exclude from con- 

 sumption streams, pools and ditches known to carry the infec- 

 tion. I have therefore gone to work on this theory and am en- 

 deavoring to solve the question of providing filtered or at least 

 uncontaminated drinking water for the work animals not alone 

 when at home in their respective stables but also while at work 

 in the fields. This requires the filtering of large quantities of 

 water, which often carries a great deal of suspended soil, and be- 

 sides, the transportation or piping of such purified water to fre- 

 quently distant fields in sufficient quantities to provide from 3 to 

 5 gallons for each animal when fed at noon. Whether the arte- 

 sian water obtainable in many places is free from the infection 

 has to be determined, and the constant reinfection of rest pas- 

 tures (Sunday pastures), and streams leading to or through 

 them must be controlled. The destruction of the parasites within 

 the animal organism, medicinally, is at present despaired of, but 

 may be accomplished by antitoxin or serum treatment since it has 

 already been demonstrated that the injurious effect of some in- 

 testinal parasites- — tape worms for instance — is due to poisonous 

 products excreted by them, and not to mechanical or nutritive in- 

 juries. And finally the eradication of the parasite from the Ter- 

 ritory must be attempted along the same lines as with other dis- 

 eases, first and principally by limiting the supply constantly 

 brought in with imported animals, from without. I have, in com- 

 pany with Dr. Elliot, made postmortem examination of a mule 

 that died in quarantine a few days after arrival and which was 

 fully as badly infested with the armed wire worm as any I have 

 seen here. 



In conclusion, if this surmise in regard to the identity of cere- 

 bro-spinal meningitis, feed and mould poisoning and the equally 

 fatal colic is substantiated, and the theory is supported by some 

 of the leading worm scientists of the country then there is every 

 reason for an unrelenting campaign against the parasite in ques- 

 tion, and I trust to be able to report progress along the lines indi- 

 cated in my future reports. 



Kahiihii Oiiaranfinc Station. 



Though of small size as compared to the Honolulu and Hilo 

 stations I feel sure that any single importation to Maui can be 

 accommodated within it. The arrangement of paddocks, stalls 

 and chutes is almost ideal, and when a number of the trees 

 which now stand in the paddocks have been removed it will be 

 difficult for any importer to find anything to criticize. The water 

 supply is abundant and convenient, and an isolation paddock for 

 suspicious cases of infectious diseases fills a long felt want. 



Dr. Fitzgerald has already done a considerable amount of test-
