Charles River Dam Conference.

The first of a series of private conferences by expert engineers, representing those who are opposed to the construction of the Charles River dam, will be held today at the rooms of the committee, 14 Beacon street. From the material gathered at these conferences, together with the great mass of testimony already received, the committee will make out its report, which is intended to be complete by next December. Definite action upon the proposed dam will probably not come until the session of 1903.
