picious case has been reported since is ample proof of the thor- 
oughness of the work. 
When the regiment returned to Leilehua shortly after noon on 
October 13 everything was ready for the animals, but as a further 
precaution every horse and mule was inspected before being al- 
lowed to go to its stall. 
The following day another suspicious case was reported and 
the same is still kept segregated; the mallein test has been ap- 
plied with negative result, and three guinea pigs inoculated intra- 
abdominally with the nasal discharge have failed to develop 
symptoms indicative of glanders. The animal has been visited 
regularly, but until every possibility of infection has disappeared 
it will be continued in quarantine. 
SHEEP DISEASE ON LANAI. 
Appended to this report wdll be found the correspondence per- 
taining to an outbreak of disease among the sheep on the Island 
of Lanai, where the assistant territorial veterinarian is now tem- 
porarily located. The deputy Territorial veterinarian from Maui 
is also on the island, the two cooperating in an effort to reach 
some definite conclusion as to the nature of the epidemic which 
has carried off a great number of animals. From the description 
forwarded by the manager of the Lanai Ranch it would seem that, 
ever since another epidemic among the sheep was investigated 
during the latter part of last year, a full report of which will be 
found in the annual report of this division for 1910, the sheep 
have continued to die in greater or less numbers and at varying 
periods of intervals. Dr. Fitzgerald from Maui was first directed 
to investigate and report on the present outbreak, he being in- 
clined to believe that the mortality was due to musty manienie 
grass, for which diagnosis there is ample support. The manager, 
however, leans toward a theory of an infectious disease, and 
even though I have been unable to find in the evidence submitted 
any reasonable grounds on which to base the diagnosis it was de- 
cided that so long as the sheep continued to die it would be better 
to make a bacteriological and microscopic investigation, and with 
the consent of the president of the Board, Dr. Case was instructed 
to equip himself with a complete outfit for this work and is, as 
stated, now looking into the matter, Dr. Fitzgerald conducting 
the field work and Dr. Case the laboratory work. Until the re- 
sults of this investigation have been received and further worked 
up, it would seem better not to express any opinion on the sub- 
ject, even though much could be said on the probable cause of the 
many deaths. Most of this is contained, however, in the corre- 
spondence submitted herewith.
