A gauging of the maximum flow of the week at the 10-inch outlet, reduced to 3-inch radins, gave a depth of flow of 1.75 inches. A similar gauging in the 6-inch laundry sewer gave a maximum flow at the time of greatest use of 2.25 inches. The stream discharged by the 10-inch sewer would fill a pipe 2.96 inches in diameter running at the same velocity. The stream discharged by the 6-inch laundry sewer would fill a pipe of 3.51 inches running at the same velocity. The total sewage discharged by both sewers-the maximum flow from a population of 659-supposing its velocity to be the same, would fill a pipe 4.58 inches in diameter. Some light is thrown on the value of this investigation by the fact that the sewer committee of Taunton seriously proposed that the State of Massachusetts should, in consideration of an outlet being furnished for this sewage, join them in constructing a main sewer several miles long, a large part of it being over 5 feet in diameter, the estimated cost being $114,000. All of which is respectfully submitted. Dr. T. J. TURNER, Secretary National Board of Health. GEO. E. WARING, JR. APPENDIX H.
