26 Director's Annual Report. 
form of ethnological specimens. The first was for the purpose of 
securing fresh specimens of the Hawaiian rat, which, it was 
generally believed, was extinct. Altogether nine were secured 
in the flesh, with fragments of many skeletons, and all the material 
on hand, except two live rats, were sent to Dr. Witmer Stone, of 
the Philadelphia Academy of Natural Sciences, for description. 
Several petrels, crustaceans and lizards were secured at the same 
time. The second trip was mainly for the purpose of aiding 
Mr. T. G. Thrum in the completion of his list of Hawaiian heiau. 
Mr. Thrum’s work has been of great value to us in our own heiau 
researches. 
‘“Of other work, Dr. W. D. Alexander’s unfinished manuscript 
of ‘‘A Critical History of the Hawaiian People’’ was handed to 
me for the insertion, if possible, of the names of the authorities 
quoted. It is highly probable that had Dr. Alexander lived to 
complete his work, these authorities would have been exactly 
quoted as a matter of course, and no one would be better able 
than the doctor. Several months were spent among the books of 
Dr. Alexander, the Historical Society and the Museum, and the 
manuscript put in the best possible order for publication. I will 
prepare an index after the work is in type. As authorized by the 
Trustees, I engaged Mr. Y. E. Tseu to continue the platting of 
the heiau from my measurements taken some years ago, and as 
the platting continues I am writing out the descriptions. The 
work is progressing, but not so rapidly as I expected, as the lapse 
of time has necessarily made it difficult to recollect detail.’’ 
Entomology. ‘‘The Helms collection of insects, purchased 
from the heirs of the late Dr. Richard Helms, arrived from Aus- 
tralia in June, 1915, and the work of the Honorary Curator since 
then has been devoted exclusively to it, cleaning and repinning 
specimens where necessary, repairing those that were broken in 
transit, and getting the whole in readiness for transferring to the 
Museum cabinets. The collection was contained in ninety-two 
insect boxes of several sizes, some of which are very undesirable 
for insect preservation, and the collection will be transferred to the 
new steel cabinets as soon as possible. 
‘‘All the chief orders of insects are represented in this collec- 
tion, but by far the greater number of specimens belong to the
