18 IOWA STUDIES IN NATURAL HISTORY 
of the vicinity of Suva Harbor, and Mr. Fell sent us a sketch 
map of Makaluva and vicinity. We took few books, but in- 
eluded Alexander Agassiz’ ‘‘Reefs of Fiji’’ and Dr. Wayland 
Vaughan’s ‘‘Corals of Laysan Island.’’ Dr. Vaughan very kindly 
gave me the method that he had found most successful in killing 
coral polyps in an expanded condition. A few entomological, 
botanical and geological books and pamphlets were also included. 
In the matter of commissary we decided to depend almost en- 
tirely on what could be found in the localities visited and made 
no mistake in so doing. We did, however, on the advice of the 
University dietitian, Professor Ruth Wheeler, take along a sup- 
ply of milk powder called ‘‘klim’’ and found it very satisfactory 
at Makuluva where we should otherwise have had difficulty in 
securing milk of any sort. A small medicine chest with contents 
suggested by Dr. C. P. Howard of our college of medicine was 
included in our outfit. The military department of the Uni- 
versity very kindly provided first aid kits for each of us. For- 
tunately, however, we had little occasion to resort to either, as 
we were all in good health during our stay at Fiji, and well 
equipped physicians were available in New Zealand. 
I have found from experience on various expeditions, mostly 
in tropical regions, that the life of a normally healthy man or 
woman engaged in field work is about as safe, so far as health is 
concerned, as it is at home. Among the forty-five persons forming 
the make-up of the parties to the Bahamas, Barbados and An- 
tigua, and to Fiji and New Zealand, there was remarkably little 
ill health of any kind; no more, indeed, than would likely have 
been experienced during similar periods in Iowa. A few mild 
cases of indigestion and slight fevers due to prolonged exposure 
to the tropical sun are about all that I recall, and in these cases 
recovery was quick and complete. An out-of-door life, good plain 
food and regular habits can ordinarily be depended upon to main- 
tain at least average good health. 
In the matter of clothing we were confronted with the fact that 
we would be in a tropical country while at Fiji and in a winter 
climate during our stay in New Zealand. A complete outfit for 
both summer and winter had to be provided for each person; also 
mosquito netting, water-proof blankets and a small kit for camp- 
ing purposes, particularly in Fiji. We found many useful con- 
trivances at reasonable prices at an ‘‘army store’’ in Iowa City.
