This line of buckets is 1!)"'.50 long, and in some of the dredges the buckets have a capacity of 350 litres and in others 300 litres. The lower roller or bearing, over which the buckets pass, can be elevated and thrown forward of the boat so that an excavation may be made in advance where the banks are above the bottom of the hull. These twenty dredges were supplied with ordinary chutes for the delivery of the earth into barges at the side, but afterward longer chutes were constructed so as to deliver the materials at a distance of 25n, .00 from the dredge. Even these long chutes were found insufficient, and forty other dredges were ordered, four of them made with chutes (0'."00 long, eighteen with chutes 70m.00 long, and the others with the ordinary chutes. These dredges resembled in their general construction the first twenty, but the length of the hull was increased to 33'."00; the breadth to 8m.30; the depth to 3, M.16, and the draught reduced to lm.50. The engine had the same nominal power, exerting easily upon the pistons a force of 7,875 kilogram-metres. The boiler had a heating surface of 108 square metres. The dredge buckets had a capacity of 400 litres in some, and 300 in others. The dimensions of the transverse section of the links which united these buckets into an endless chain were 0'."18 by 0U, .058.
