Estimates were made by Mr. Smeaton, of the several lines and various dimensions proposed for this canal; but the one under which the work was commenced amounted to £147,337, but augmented to £149,244, 8s. by the additional expense incident to a change in the line, which was effected under powers of an act of 11th George III. entitled, An Act to explain, amend, and render more effectual, an Act made in the Eighth Year of his present Majesty's Reign, entitled, An Act for making and maintaining a navigable Cut or Canal from the Firth or River of Forth, at or near the mouth of the River of Carron, in the county of Stirling, to the Firth or River of Clyde, at or near a place called Dalmuir Burnfoot, in the county of Dumbarton; and also a collateral Cut from the same to the city of Glasgow; and for making a navigable Cut or Canal of Communication from the Port and Harbour of Borrowstounness, to join the said Canal at or near the place where it will fall into the River of Forth.
