any civilized post. This type of camera has the advantage of portability and, 
with the ground glass, accuracy of focus. The double extension bellows further 
allows, either for long focus lenses or for close-up pictures of small objects or 
details. I have found it to be a very valuable machine, although I did not 
have one myself at the time. So much for still pictures. 
Besides our still pictures we hoped to get some valuable ‘‘movies” of the 
country and its people. For this I took an ‘‘Eyemo” put out by the Bell and 
Howell Company. I selected this on account of its apparent ruggedness, com- 
pactness and relative inexpensiveness. I may state here, that if one expects 
to make moving pictures a feature, it will be wiser to get a more expensive 
outfit which will give greater latitude. Not having had experience myself 
with such outfits I cannot justifiably advise further. However, I found the 
Eyemo to be very satisfactory throughout the trip. 
Concerning taking extra cameras, I am in a mixed mind. I took one my- 
self —a4 x 5 plate camera — but before half the trip was over, it had become 
so rusted and mildewed that I sent it home entirely out of commission, whereas 
the graflex being used daily, never ‘‘missed fire’’ during the entire trip. The 
reason for this was that the constant use kept it from corroding and rusting. 
It was always wiped after getting wet. It was aired and cleaned on every 
opportunity. The reserve outfit on the other hand was in a ‘‘water proof”’ 
trunk and because it was not being used was neglected. I never missed it after 
it was sent away. 
A tripod will be necessary but the variety can be suited to the individual’s 
taste. In case one is using a wooden tripod, remember that the joints will 
swell in the rainy season. I found that this could be counteracted by shaving 
the legs down until they didn’t jam. I also found that the three-ply head 
came unglued — but again, a supply of brass screws remedied the defect and 
the tripod is still doing me good service. I might state here that perhaps the 
best way of considering equipment is to examine each part of the outfit in the 
light of to what it is going to be subjected. How is it to be repaired? Then 
take the things necessary to repair it, for there is no foolproof outfit devised 
for the tropics, and in so far as you are out of touch with further supplies it 
is wise to be self-sufficient. For this reason I took adhesive plaster, assorted 
brass screws from the smallest size up, and ambroid, a form of glue which 
‘sets’? in moisture. This latter material I have found to be invaluable. On 
our trip it was extensively used by many members of the Expedition for equally 
many purposes. Even China teapots were stuck together and withstood the 
ravages of hot tea. 
The next question is that of films. Glass plates are more or less out of the 
question on account of the weight. Also the manufacture of film has advanced 
sufficiently so that the more portable materials are just as good. These are 
cut film, film pack, and roll film. 
My own personal reaction to the film question is in favor of cut film. There 
is more latitude in the emulsion and because the base is stiffer they are more 
readily handled in developing. The disadvantage, however, is the fact that
