Stipulated into Cause of Bowers vs. Von Schmidt. Buckets have no bottoms but revolve around a stationary water tight arm having an opening into an injuriorhopper or mud receiver. This hopper is curved to form a half circle at the pipe isadlocul through the side of the hollow stationary drum, and from this pipe a large, strong suction hose passes around the bar of the boat and to secured to the suction pipe of. centrifugal Pump. These pumps havens valves and coarse substances can pass through them I believe thy will cary a heavy percentage of muct and ound becaus they take up lan bark without differently. An injic. wil pipe may send a strong set through the bottom of the hepper to cut it up if necessary. wheel und intercor drum rise tha sliding frame between upright guides. I am of the opinion that the suction pussy, alon: well do the work because a large amount of water will come up with the mud and as the hopper is deep I think the weight of mud and water would force the water into the stream from the force-pump and this alone would also handle a large amount of mud.
