Rh cubic yards, or upwards of 17,000,000 tons. The dredging plant of the Clyde Trust comprises—

6 steam dredges, 14 steam hopper barges, 1 steam-tug, 3 diving-bells, 270 punts, and numerous small boats.

The expenditure for wages of crews, coal, and stores amounted in the year 1871 to fully 14,000, and for repairs 10,775. The value of the dredging plant employed is about 140,000. Mr Deas has also kindly furnished the following tables, from which the reader will see the gradual increase that has been made on the size of the dredging machines to meet the increased depth of water and growing necessity of increased accommodation for the larger class of vessels which now frequent the river:—
