We illustrate below a dredger of simple construction, well calculated
for doing useful work on shallow streams. The barge is 54 ft. long, 22
ft. beam, and 6 ft. deep. Her draught of water is under 4 ft. Built by
Rose, Downs & Thompson Hull. Our drawing explains itself. It will be
seen that we have here a swiveling crane and grab bucket, and that the
stuff dredged can be loaded into the barge and conveyed where necessary.
The lifting power of the crane is one ton, and in suitable material such
a dredger can get through a great deal of work in a comparatively short
time.--_Engineer_.
