50 ALES' HRDLI&KA 



An important item never to be neglected in connection with an 

 expedition to primitive tribes is to take along an ample supply of small 

 change, which is invariably rare in out-of-the-way regions; and the 

 money should preferably be in used coin which will not be regarded 

 with suspicion. 



Cameras. It is best to carry two cameras a pocket kodak for 

 scenes on the road and instantaneous exposures ; and a larger camera, 

 preferably with glass plates, for portrait work and larger landscapes. 

 Both cameras should be provided with the best lenses obtainable, and 

 be well tried out in every way before departure. A stereoscopic camera 

 is advantageous. 



Boxes. The cameras, instruments, medical supplies and other 

 articles are carried in standard canvas-covered boxes, with rounded 

 corners and rope handles. These boxes should be of such a size that 

 they may be conveniently carried on the backs of men, burros, horses, 

 mules, llamas or camels, as well as in a railroad car or a wagon. They 

 should be made of strong, light wood, preferably gum, well jointed, 

 and have all the hinges on the inside to make robbery difficult. The 

 best way of fastening is with strong padlocks. The size of the boxes 

 found most convenient by the writer (except for the instrument case 

 which should fit these) is, externally, height 18 in. (46 cm.), breadth 

 20.5 in. (52 cm.) and antero-posteriorly 14 in. (36 cm.). In field these 

 boxes will serve various useful purposes, such as chairs and tables, and 

 at night as a wind break, or base over which in case of rain may be 

 spread a sheet of canvas converting the whole into a sort of shelter 

 or tent; while on the return voyage they may be used to transport 

 casts, photographic plates and specimens. In places where the ex- 

 aminations are carried on the boxes may again serve as chairs and 

 tables; and if there are enough of them, at night they make a very 

 good elevated bank on which to spread one's bed. By suitable inside 

 partitioning one of these boxes may be fitted for medical supplies, 

 one for kitchen utensils, one for the cast-making outfit, another for the 

 photographic apparatus, still another for trinkets and smoking sup- 

 plies for the natives, etc. The boxes are numbered or otherwise 

 marked so that any desired one may be readily found when needed; 

 and a duplicate set of keys is provided for a case of loss. 



Companions. This is a matter of much more consequence than 

 might at first appear. In general the most satisfactory procedure is 

 for the observer to engage only such companions as he may need 

 in traveling from place to place. The taking along of friends, co-
