ANTHROPOMETRY 61 



workers, or even a photographer, not only risks their exposure to 

 sickness and greatly increases the expenses, but is often productive of 

 much friction as to plans, food, time of starting, etc. It may further 

 lead to difficulties in fixing blame for accidents and especially of 

 credit for discoveries ; and will frequently be productive of delays and 

 inconveniences, for often where one can find what he needs, two or 

 three cannot be accommodated. Free hand, freedom from anxiety 

 for others, undivided responsibility, and undivided credit, are precious 

 assets which should be carefully guarded by the explorer. 



Miscellaneous. — Photographing and even measuring may have to 

 be done by the roadside, in the field, or under other untoward circum- 

 stances which often will call for the exercise of not a little ingenuity. 

 He may at first be received with suspicion and suffer for the faults of 

 others. But with a fair interpreter, friendly, honest attitude, and such 

 small gifts as may best be fitted to the occasion, the student will as 

 a rule secure the needed observations. It is almost needless to say 

 that his own health and strength will demand rational attention, for 

 he will travel in and out of season, may have to endure exertions and 

 privations, and be subject to infection through contaminated water, 

 spoiled food, insects, and contact with diseased persons. All this can 

 in a large measure be counteracted, and if so the field expeditions be- 

 come to the worker not only a source of priceless experiences and acqui- 

 sitions, but also of a deep recuperation.
