Another Kind of Dredger

Retracing a stretch of the Whangpoo, one comes to another kind of mud-raising, This has no pipe-line connecting with the land. A fascinating work ix in process. The main craft, housing a steam engine and pump, has, lying alongside, a low cupped barge which once seen is invariably to be associated thereafter as the mud-collector of the Whangpoo. The bifid main craft seems built around central ire dredging buckets, which, linked to one another and the central apparatus by sturdy cables and chains, have free access to the water. Thirty-two of these buckets revolve with deliberation and dignity, under pressure from the home engines. They scoop downwards to the Dottom of the river, and then upwards like a giant funicular tram, filled, each bucket to the brim, with the hard clayish contents of this part of the river. At the top of the ladder, each bucket deposits, elegantly, with a minimum splash, its ton of slime into a vast square container, which in turn shoots it with a' modifying supply of water into the waiting barge below. Each of these mud-barges, of which the Board owns 21, holds 500 tons. As each of the two large bucket dredgers possessed by the Board are capable of dredging 700 tons an hour, it would seem that the Yangtze ud its subordinate in time might fruitless channel gels into one of the W.
