to be found in stagnant water on the level land, and in rice-fields &c. In deference, however, to the views of the Medical Officers and the system already inaugurated, I consulted Mr. Chatham as to whether some effective method could not be employed which should not involve so great an outlay as the construction of permanent concrete water courses would necessitate, and he suggested a modified scheme. Since he has had so large an experience of this particular work, and since it has nothing to do with Railway construction, I directed him to undertake the construction of a short experimental section (100 to 200 feet) on the lines he proposed on the completion of which I should be able to judge as to its effectiveness and the cost involved. This would relieve the Railway of wholly extraneous work, and avoid the necessity of withdrawing labour and supervision from the construction works.
Fortunately, however, before this trial section had been begun Dr. Thomson reported that the issue of quinine had been so effective in arresting Malaria that he considered that the nullah training operations might be abandoned. He writes that whereas the incidence of Malaria should have been increasing during the last few months there has been a steady decrease since July when the quinine arrived.
