of a general breakdown. Many of the writer's compatriots have not 

 yet, after many years, learned this and they are paying the penalty 

 for it. When one becomes tired in the field as elsewhere he cannot 

 do good work. Five or six hours is long enough for a white man 

 to work outside, in the tropics. 



11. PROTECTION. 



Firearms except for hunting purposes, are generally unnecessary 

 in the Philippines at the present time. A colleague of the writer 

 was killed by natives some years ago, while he had two loaded 

 revolvers strapped on him. If they set out to kill one they can 

 very easily find ways to do it. Often the possession of a revolver 

 merely incites them to murder. 



A white man should never travel alone in the Philippines. If he 

 has no white companion or assistant he should have a native with 

 him. Most of these native companions, ^muchachos" or assistants 

 are very helpful and faithful and will save one much trouble, 

 especially in the matter of interpreting, finding guides, assisting in 

 case of accidents, etc. 



12. HYGIENE. 



So much has been written about this subject that the writer 

 almost hesitates to add anything to it, but it is all so important 

 that even at the risk of repetition he will make a few comments. 

 First he wishes to insert a short memorandum from his colleague 

 Prof. Frank G. Haughwout, parasitologist of the Bureau of Science 

 of the Philippine Government, who has kindly summarized the 

 essential features concerning important Philippine diseases. 



,,The traveller on a scientific mission to the Philippines runs 

 relatively little risk of contracting the so-called tropical diseases 

 provided he exercises a few simple precautions. Those which he 

 must be on guard against are the various intestinal disorders and 

 malaria. Fortunately, it is rather easy to avoid these. 



Before embarking for the tropics the traveller should be vaccinated 

 against smallpox, typhoid fever and the paratyphoid fevers. He may 

 take the vaccination against cholera on arriving in Manila. In the 

 latter case the procedure is similar to that in vaccination against 

 the typhoids. The reaction, if any occurs, is exceedingly mild and 

 the immunity conferred lasts for several months. No person should 

 embark on any expedition to the tropics before ascertaining his 

 ability to tolerate quinine in the doses administered in the treatment
