16 IOWA STUDIES IN NATURAL HISTORY 
check used in addition to the original discount for exchange. 
As we were responsible for the expenditure of university funds 
in the purchase of equipment and transportation of collections, 
and, as the exchange at various rates had to be carefully com- 
puted, it was no easy matter to keep our financial accounts 
straight. Sometimes the formality of securing receipts from 
native helpers, particularly in Fiji, was perplexing and their 
signatures weird specimens of chirography. 
Having given up the idea of dredging, the devising of equip- 
ment was a comparatively easy matter. Three or four compound 
microscopes and an equal number of dissecting instruments 
met our needs, and, of course, each of us carried his own pocket 
lens. We intended to make much use of photography on this 
trip but decided to abandon the idea of taking motion pictures. 
On the Barbados-Antigua expedition we took a good moving 
picture camera and an operator with very satisfactory results, 
but the expense of employing an operator, paying his transpor- 
tation, buying the necessary films, ete., was now too great for 
our slender means. The actual scientific results from motion 
pictures are not very great, although they are extremely pop- 
ular and an aid to the popularization of scientific subjects. 
We therefore contented ourselves with small cameras and 
good lenses, each member of the party taking the instrument 
most suited to his purpose and personal preference. We also 
took a microphotographie camera, particularly for use in mak- 
ing pictures of expanded living coral polyps. But that instru- 
ment came to grief before it had been of much service on ae- 
count of the shutter going out of commission—one of the re- 
sults of shipping a good deal of water in an awkwardly managed 
landing at Makuluva, where the surf was very bad. 
Mr. Glock was our official photographer and did good work, 
using a Premo No. 12 with film packs; but he was so often 
separated from the rest of the party, with the exception, of his 
fellow geologist, Professor Thomas, that he accomplished little 
for the zoological and botanical members. Professor Wylie was 
probably the most expert photographer among the biologists and 
his beautiful negatives of the luxurious tropical trees and plants, 
particularly of the wonderful tree-ferns in the interior of Fiji, 
would be hard to surpass and will be used in the botanical lecture 
rooms for years to come. He used an Eastman 3 A Special
