Fig. 1. Holland. A Netherlands Steam Oyster Dredge, a side-wheeler extremely 
BROAD OF BEAM (BELONGING TO MR. OCHTMANN, BERGEN-OP-ZOOM). 
The figure shows the long windlass of a donkey engine placed amidships, a reel at the stern ove; which the in- 
coming lines pass, and a high -arm bar which helps to raise and empty the d redge. An example of theordinary 
dredge will be seen hanging at the stern. (Page 386.) 
Fig. 2. Ostend, Belgium. The Main Canal which supplies water to adjacent Oyster 
Reservoirs, as seen at low tide. 
Locks occur at various points, one of which is seen in the background. From that direction enters the fresher 
water which serves to reduce the density of the water mass of the canal. The degree of the fall of tide may be 
seen indicated by the water-line stain on the masonry wall. A sluice gate supplying and draining an adjacent 
oyster reservoir occurs near where the figure on the bank at the right is standing. (Page 389.)
