The condition of the harbour is gone into at length, one new fact being noted, to wit: that the water is so foul that the bottom cannot be seen two feet below the surface, while at Marianao, eight miles away, the bottom at twenty feet is plainly visible. Both General Greene and Surgeon Davis are of the opinion that the harbour is not such a menace to health as are the cesspools, slaughter-house, and general filth of the city, and that it should come last in the cleaning process. In recapitulation, General Greene says: "From the foregoing it is apparent that the first steps toward sanitation are the improvement of the slaughter-house, the cleaning of cesspools, the inauguration of a proper system of street cleaning, and the devising and rigid enforcement of health regulations. I have therefore advised that immediately on taking possession of the city government a board be appointed, consisting of three army surgeons and two civilians--one from New York and one from Chicago--of long experience on the Health Boards in those cities; that this board study the sanitary conditions of the city and draw up a new code of sanitary regulations, including the management of the hospitals; and that this code be rigidly enforced by the new city police, assisted by such number of sanitary inspectors as may prove to be necessary. In this manner I believe that the sanitary conditions can be improved and the death-rate enormously reduced before the next rainy season sets in. The death-rate in October last was at the rate of 133 per 1000 per annum; in December it had been reduced to 106, and with only two deaths per week from yellow fever. "In order completely to stamp out yellow fever it will be necessary to destroy a limited number of the worst infected houses occupied by the poorest classes, to construct a system of sewers, and lay new pavements. This will involve a very large expenditure of money, and it is not at present clear how the city can raise this money. It is probable, however, that a feasible financial scheme could be devised after thorough study, and in the meantime a commission of engineers should be appointed to study the problem, and either acquire the existing surveys by purchase, at a fair valuation, or else make new surveys, and a definite report covering the whole ground, so that the matter may be intelligently considered."
