a colt at foot was turned into the pasture, and, whether due to the 

 change in feed, the drain on her system in suckHng the colt or 

 to the exposure to the then prevailing cold winds and rain, she 

 promptly developed acute glanders and proceeded to scatter it 

 iDroadcast over the pasture. Her condition was noticed shortly 

 afterwards, but not until one of the plantation mules had de- 

 veloped the disease. The mare w'as then removed from the 

 l)asture and was later found only with difficulty. On post-mortem 

 examination she was found to be a typical "carrier" with old 

 characteristic scars in the nose, and numerous calcareous nodules 

 in the lungs, the lesions indicating that the disease had remained 

 dormant in her system for some considerable time and had only 

 recrudesced with the change to the open pasture. The local 

 deputy. Dr. Fitzgerald, immediately upon locating and destroying 

 this animal, rounded up all horse stock with which she had come 

 in contact since developing the disease, submitting them all to 

 the mallein test and destroying six, which gave typical reaction, 

 all of them being animals of little or no value and some of which 

 showed old lesions in the lungs, indicating previous infection. 

 All of these animals belonged to the same owner as the mare in 

 question. 



That only one plantation mule should have become infected 

 speaks well for the natural resistance possessed by animals kept 

 in the prime of condition, which was the case with all of the plan- 

 tation work animals, and there can be little doubt that had they 

 been covered with open harness galls and raw chain sores, such 

 as was frequently the case a few years ago on this as on many 

 other plantations, the infection would have gained entrance into 

 many another animal system. Not until three weeks after it was 

 believed that the outbreak had been completely suppressed did 

 one more mule show suspicious symptoms, wlien at the rec|uest of 

 Dr. Fitzgerald and with the I'oard's permission I went to Kahului 

 to look over the situation. This case proved, however, to be one 

 of ej)izootic lymphangitis, a disease in every respect as dangerous 

 as glanders, except that it cannot be transmitted to man, but other- 

 wise absolutely independent of this disease and non-reacting to 

 the mallein test. It is the same disease which some years ago 

 caused such heavy losses to the FI. C. & S. Co. and to the Maui 

 Road l*>oard, but wliich since has been encountered only in scat- 

 tcrerl and very rare cases in the Islands. It was nevertheless 

 decided to submit the entire Waihce jilantation stable to the mal- 

 lein test, and also to retest the outside aniniaF ^till i-nnning in 

 the rest ])asture. 



As not a single reaction was dbtained, I'ven tlmugli the ex- 

 tremely sensitive intra-dermal method was used, it is safe to con- 

 clude that the glanders orUbreak was suppressed with the destruc- 

 tion of the reactors to the first test, and that the ap])earance of 

 the later case of epizootic lymi)hangitis was merelv a coincidence. 

 It was nevertheless recommended that the \\'aihec stables be
