    • Description:
      A few suggestions for foreman to make drainage easier and better.

      The letters "MCWA" stand for "Malaria Control in War Areas". It is a very important part of the war effort. Because it is important and because every bit of it is being paid for from Public Funds, those of us who are doing the work must do the best job we can and do it at the lowest possible cost. Every time we waste money by making a careless mistake or by digging a ditch that won't do the job it was built to do, someone has to buy extra war bonds or pay extra taxes. Do a good job .... a job that will work .... and a job that will cost just as little as possible. There are many ways to drain water from a pond or swamp. Some you may have used before--others you may not have thought of. In the next few pages a few suggestions are made, and a few common mistakes are pointed out. Look these over. They may aid YOU in doing a better job for our country at lower cost. Study the suggestions, and see if they will fit your drainage problem.
