163 I am equally confident that until measures are taken to reduce moisture in the soil and to allow its free permeability by air at all seasons of the year, the efficiency of the Army will be, as now, year after year impaired by preventible sickness. The question of dealing with malaria-producing sources beyond the limits of cantonments is a much more difficult matter, and I quite allow that it would be out of the power of Government to undertake at once the sub-soil drainage of vast tracts of territory. I fear that this great source of much of the disease among the native as well as among the European population is without practical remedy; but if Government were to set the example in camps, and by so doing demonstrate to the people of India the great advantage to be derived from such a course, I have no doubt that in course of time, though this may perhaps be still far distant, such action will surely be taken. England itself two or three centuries ago was an intensely malarious country. " James I. and Oliver Cromwell, says Murchison, both died of ague; and the latter of these rulers, speaking of ague, makes use of the following oft-quoted words: matrem pietis- simam, fratres, sorores, ancillas, nutrices, conductitias, quotquot erant intra eosdem nobiscum parietes, ac fere omnes ejusdem ac vicinorum pagorum incolas, hoc veneno infectos et decumbentes vidi. The country surrounding London was in Cromwell's time as marshy as the fens of Lincolnshire now are. But at the present day owing to the almost universal drainage and cultivation of the soil agues have, save in a few isolated districts, almost vanished from this country." I cannot but believe that as education spreads the intelligence of the natives will lead them to adopt similar measures, but they cannot be expected to believe in the benefits conferred by underdraining a soil, unless Government sets the example. For the present the only practical course with reference to in- sanitary conditions of the country beyond the limits of cantonments appears to be that due care should be taken in the selection of the site of barracks and to see that they are not unusually exposed to malaria-producing causes arising beyond the boundaries of the cantonment. Something may perhaps be effected by the extension of tree planting and in paying especial attention to keeping the main channels of the surface drainage free; but beyond this I fear but little can at present be done. It surely requires no argument to prove that a damp barrack must be an unhealthy barrack. Roofs which leak should be reconstructed, whilst the verandahs should be protected from rain beating in. Gutters round the eaves of the roofs are required to prevent the storm water dripping from them, and the roof water should be carried to a distance from the barracks through an impervious channel. It is too late now for measures to be taken to provide air perflation under the ground floor of barracks; but the top layer of the solid matter with which the plinths are filled might be taken out for a certain depth and be filled in, as suggested by the Army Sanitary Commission, with good Portland cement con- crete. Many of the barracks are injudiciously ventilated, the men being exposed to draughts whilst lying on their cots. If the doors recommended by the Army Sanitary Commission and by Mr. Lumsdaine were to be constructed, much of this would be obviated. Iron receptacles below the spouts for bathing rooms in barracks should not stand in masonry pits but on the ground, the plinth ought always to be of sufficient height to allow of this arrangement, but in many of the barracks it is too low. In such cases a low but long receptacle might be made to catch the bath- room water, or, better still, it should be discharged direct into the puckaul. No wash-houses should be under the same roof as the dormitories, and in barracks, where this is the case, separate wash-houses should be provided. The wastage water from the wash-houses should not be deposited on the ground; it might be utilized in watering roads if it cannot be carried through a drain to a distance. I regard, as I have previously said, the present standard latrine as a distinct disease cause, and I consider it to be very probably one of the sources of enteric fever.
