The huge dredger built for keeping open the Mersey Channel is aptly named the Leviathan. She is 465 ft 9in in length, and is capable of pumping up 10,000. tons of sand and.discharging it into her bunkers from a maximum depth of . 70ft it 50 minutes time. The pumping plant consists of four independent centrifugal pumping engines, each of 800 horee-power. Her capacity is shown by the fact that in a five hours' test, 20,000 tons of material was lifted from the Channel into the hoppers, carried 10 miles, and dumped. In a favourable year of work the Leviathan will dredge and remove to a suitable dumping ground at least 20.000,000 tons of sand. •
