had some few years ago, surveyed the ground between Boston and the Long Pond, distant about ten miles from the city, and reported a plan quite feasible, and, considering the advantages promised, of reasonable cost, by which a perpetual and abundant supply to the whole city, could be derived from that source and delivered at a sufficient elevation, to supply the upper stories of the houses. Absorbed possibly in other great public works, especially the Western Rail Road, the city of Boston has not as yet decided to attempt the new aqueduct.
