populated districts. Had the necessary topo- 

 graphical changes been considered or foreseen, the 

 advantage of selecting other camp sites would have 

 been obvious. 



The proximity of proposed camp sites to exten- 

 sive Anopheles producing areas, or native villages 

 in which many cases of malaria exist, merits careful 

 consideration. 



The old idea of locating a house on a small hill 

 to escape "malaria miasma " is of little importance. 

 The slight advantage gained is only that of in- 

 creased air motion causing temporary protection 

 from mosquitoes. 



The selection of poor locations for camps, and 

 the creation of new and extensive Anopheles pro- 

 duction due to topographical changes, and other 

 causes, produced fluctuations in the malaria sick 

 rate, many of which might have been avoided. 



By studying each problem separately and 

 devising methods to solve it, and concentrating 

 effort on the most important points of attack in 

 order to obtain the largest net returns for each 

 dollar expended, we were able to reduce, from year 

 to year, the malaria sick rate of the force employed. 



The malaria charts show the results accom-
