DITCHING AN OPEN STREAM IN THE CITY OF LITTLE ROCK FOR THE CONTROL OF MOSQUITO BREEDING For many years people living along this stream have suffered from malaria. Preventing the mosquitoes from breeding here destroys the car riers of the disease and thus safeguards the thousands of our young men who have come to traininCamp Pike. More than 80miles of open ditch drains have been maintained in Little Rock during the past summer in such a way as to prevent mosquito breeding. This view shows a ditching gang at work clearing the small obstructions from the stream and trimming the rough banks so astoprevent eddies forming inwhich mosquito eggs may be deposited.
