The Board can at present advise that both methods of disposal suggested, with the slight modifications mentioned, will efficiently dispose of the sewage. The choice as to which should be adopted should depend to a considerable extent upon the relative cost of the two systems, taking into account all the items of first cost, including land damages, and also the annual running expenses and maintenance. The choice may also be governed by minor considerations of local nature, and by the possibility of any interference with the attractions of the town as a summer resort.

EASTHAMPTON. A committee of the town of Easthampton applied to the Board (November 14) for its advice relative to a proposed system of sewerage having its outlet into a brook below the town and a short distance from the Manhan River. An additional request was made for advice as to the propriety of building a part of the system with temporary outlets into certain mill-ponds, and into the Manhan River opposite the town. The Board repliecl as follows:

Boston, Jan. 6, 1892. This plan consists of a system of pipe sewers which will deliver their flow into a main pipe laid through the Williston Mills Pond. This main pipe is to pass around the easterly end of the dam and discharge into the brook below the dam, at the culvert under the Mt. Tom Branch Railroad, not far from the Manhan River. It is further understood that the system is to take sewage only, and not the street or other surface water.

The Board is of opinion that the sewage can, for the present, be discharged into the Manhan River below the town, without causing any serious trouble. The discharge into the brook at the railroad culvert, a short distance from the river, as proposed, is less satisfactory; but, as any trouble which may be occasioned by such discharge can easily be obviated by extending the main sewer to the river, the Board is of opinion that an outlet at this place is temporarily permissible. At some time in the future it is probable that the sewage will have to be purified before being discharged into the Manhan River, or else entirely removed from this stream; and, with this probability in view, the Board commends the adoption of a system of sewers for sewage only, as with a system of this kind the sewage can be treated when necessary with less expense than where the volume flowing is increased by the admission of surface or other water which is not seriously polluted and could go into the nearest streams.

With regard to the proposition to dispose of the sewage of a

portion of the town for the present into the Nashawannuck and Williston Mills ponds, and into the Manhan River at points opposite the town, the Board does not advise the discharge of sewage into the mill ponds, but is of opinion that the temporary discharge of the sewage into the Manban River opposite the town is permissible, if it should be found for the interests of the town to provide such temporary outlets. The construction of a permanent outlet at a point just below the dam across the river, for a short sewer in Manhan Street, seems to be unobjectionable.

POLLUTION OF STREAMS.

The following is the substance of the action of the Board relative to the subject of the pollution of inland streams :

THE Fowl MEADOWS ON THE NEPONSET RIVER. A complaint was received from C. Sumner of Canton (July 20), concerning “a certain tract of land of about six thousand acres, situated on either side of the Neponset River, and adjoining and lying between the towns of Canton, Walpole, Sharon, Hyde Park, Norwood, Dedham and Roxbury in the city of Boston. For the last ten or twelve years the said meadows have been kept in such a state from back water, owing, it is said, to several manufacturing concerns at Hyde Park and below having their dams higher than they should be, that the stench arising therefrom is at times most unbearable, and is the direct cause of much sickness, of malarial and kindred diseases, which were said to be unknown in this locality before such state of affairs existed.” The applicant also requested that the Board would take such steps “ as were within its province, to have the nuisance abated.

The Board replied that " it might properly investigate the question as a possible source of illness, but was not aware that any legislation gave to the Board the power to abate it.”

The Board instituted an investigation at once, the results of which will be presented in a subsequent portion of this report.

ALEWIFE BROOK. A communication was received from the Board of Health of Medford (Aug. 21, 1891), complaining that the city of Cambridge was “about to widen Alewife Brook to give a larger outlet to the river for the sewage." The Board of Health of Medford protested against such action, and requested the State Board to investigate the matter. To this communication the Board replied as follows:

Boston, Oct. 7, 1891. The Board finds that practically all of the improvement relates to the portion of the brook above the tide-gates near Broadway. As these tide-gates shut out the water, the amount of water going out through them at each tide, now that the improvement is completed, is the same as formerly; namely, the amount of upland water and sewage accumulating in the brook while the tide gates are closed. After a heavy storm the conditions may be somewhat different, as the storm water, which formerly required more than one low tide to flow out, may go out in a single tide. After due consideration of the subject the Board does not find any ground for thinking that this improvement of the brook will injuriously affect Medford, while, on account of the lowering of the water, it is a manifest advantage to the portions of Cambridge, and of other towns, near the brook.
