cerned, a little attention to hygiene will render one's health 

 quite as secure as in most of our northern states. 



The traveller in these tropical regions should invariably 

 provide himself with flannel underclothing; aside from this the 

 clothing should be light, airy, and strong if he is to do much 

 travelling in the jungles. In case of a wetting, which is not 

 unusual in this region, the wet clothing should always be 

 removed as soon as possible, and a cup of hot tea or other 

 drink taken. Hard work in the hot sun is dangerous, and 

 excessive exercise should be avoided. Plenty of sleep, bodily 

 cleanliness, close attention to the digestion, and care as to the 

 kind of water used for drinking purposes, will usually secure 

 immunity from fevers and other diseases which attack those 

 who are careless in these matters. 



Sickness often prevails among the natives, but it is not due 

 so much to the climate as it is to their own carelessness, for 

 in their homes they are not cleanly,, living in blissful compan- 

 ionship with their domestic animals; they are careless about 

 food, and their drinking water is usually taken from the lake 

 or rivers in places which serve as general dumping grounds 

 for offal, or as bathing places for both man and beast. At 

 Moyogalpa the water was at times very filthy, and the party 

 found it necessary to boil it before using. This should always 

 be done until one becomes accustomed to the water even 

 where this is taken from clear streams. A good plan, if one 

 is stopping at one place for any length of time, is to collect 

 rain-water for drinking purposes. 



Liquor as a beverage should be avoided. The climate is in 

 itself sufficiently enervating, and the habitual use of alcohol 

 soon wrecks the best constitution. Those who drink to keep 

 off fevers soon find that they have exposed themselves to a 

 much greater danger. 



The damp night air should be avoided, and warm blankets 

 should always be carried, as tha nights are often quite cold. 

 A small medicine-chest should not be forgotten. This should 

 contain remedies for disorders of the digestive system, for
