This is, that the Sanitary and ShipCanal is itself a most powerful engineering aid to the further woik which must beundertaken. Considered as a mere instrument for the scouring of the bed of theIllinois River, the flow of water from the sanitary canal is worth millions of dollars, because it will save millions that would otherwise have to be spent.
