It will be observed that in a few instances, for example, influenza, meningitis, malaria, pellagra, septicemia, acute dysentery and purulent conjunctivitis the number of deaths is in excess (sometimes very much so) of the number of cases of sickness reported. This merely means that the cases of sickness in the foregoing diseases are not fully reported, if reported at all, and hence credit for these cases has not been made on the infectious disease side of the table. Efforts are now being made to obtain better reports. CASES OF TYPHOID FEVER ON WATERSHEDS-1912. Potomac River.... Jan. Feb.Mar.Apr.May.Jun.Jul.Aug.Sept.Oct. Nov.

The work of the Bureau of Sanitary Engineering was started on June 1, 1912, upon which date I took charge of the new department. Attention was immediately turned to a search for an assistant engineer of suitable qualifications. Perhaps even more care than is ordinarily necessary was required in the selection of the engineering force of this bureau, for the work was a new departure in Maryland and previous experience along similar lines was therefore particularly valuable.
