ADMINISTRATIVE ASPECTS OF THE CAMPAIGN 97 



The records of malaria calls made by physicians, described in 

 Chapter IV, should also be gone over carefully each month, and 

 any physicians delinquent in reporting should be seen without 

 delay, since it is imperative, for effective comparison that 

 complete and accurate figures be obtained. 



MAPS 



As stated in an earlier chapter a map of the community in 

 which the work is to be undertaken should be obtained and, if 

 practicable, several copies should be made of it. A scale of 1 

 inch to 200 feet or 1 inch to 400 feet is recommended.

 Fig. 63. — Mosquitoes were breeding abundantly in a little water in the old 

 kettle clinging to the bank. There was no breeding in the stream itself, how- 

 ever, owing to the activities of larva-destroying fish. 



On one copy of this map, there should be marked all the topo- 

 graphical features of the community bearing on mosquito produc- 

 tion, as found during the survey. As old ditches and channels 

 are cleared (re-channeled), as new ditches are completed, as 

 marshes are drained, as holes are filled up, as ponds, culverts, 

 streams, etc., are stocked with fish, as oil stations are organized, 

 they should be indicated on the map in an appropriate manner, 

 either by the use of symbols or otherwise.
