Opposition to Dam Withdrawn.

The Boston Chamber of Commerce, through its president, W. H. Lincoln, and its secretary, E. G. Preston, has withdrawn its opposition to the bill for the construction of a dam across the Charles River near Craigie Bridge. It was feared that the project might meet with opposition from the War Department, but Secretary Root has written that he has no objection to offer. This removes all open opposition to the bill, and makes the prospect of its being passed appear very favorable. Up to the present time the joint commission, made up of the Committee on Metropolitan Affairs, and the Committee on Harbors and Public Lands has made no report on the subject.
