The Clyde from its source to the sea, its development as a navigable river, the rise and progress of marine engineering and shipbuilding on its banks, and the leading historical, geological, and meteorological features of the Clyde Valley . a was obtainedamounting to about 2500 acres, the scour due to the ebbof which rapidly cut down into the bar, until a depth of16 feet at low-water was obtained, or 28 feet at high-water of springs. The river channel is deepened bydredging, the dredgings being removed in hopper-barges,some of them carrying 1000 tons, and deposited outsidein the sea. The dredging plant of the Clyde NavigationTrustees consists of 6 dredging machines from 40 to 75nominal horse-power; 1 floating steam digger barge; 18hopper-barges from 35 to 65 nominal horse-power, witha fleet of punts and boats, several diving-bells, & of the dredgers are capable of working in 30 water, and have lifted nearly 400,000 cubic yards ina single year. During the year 1887, 1,319,344 cubicyards were dredged. The total amount dredged duringthe last forty-three years amounts to 32,261,778 cubicyards.

Measures, however, are being takento dredge away or rather disperse the bar to the extentof 2 ft., by a macliine called a dredging plough, which isdesigned to disturb the bar and disperse the sand by airforce when the currents are setting seawards. Still, whenthis is done it will only permit vessels coming east to befully laden instead of as at present leaving freight un-shipped. The ship-owner and ship-builder can now dolittle more for the ease of an Atlantic voyage; they waitupon the harbour and dock authorities for permission toincrease the breadth and depth, and therefore the steadi-ness and comfort, of their steamers.
