To the Senate and House of Representatives:
The act making appropriations to provide for the expenses of the government of the District of Columbia for the fiscal year ending June 30, 1890, provides, among other things, that the president shall appoint three competent sanitary engineers to examine and report upon the system of sewerage existing in the District of Columbia, together with such suggestions and recommendations as may to them seem necessary and desirable for the modification and extension of the same, which report was to be transmitted to Congress by the President at its next session.
In pursuance of the authority thus conferred, on the 17th of August, 1889, I appointed Rudolph Hering, of New York, Samuel M. Gray, of Rhode Island, and Frederick P. Stearns, of Massachusetts, to make this examination and report.
The gentlemen named were believed to have such ability and experience as sanitary engineers as to guarantee an intelligent and exhaustive study of the problem submitted to them.
I transmit herewith their report, which has just been submitted to me, for the consideration of Congress.
