HOW THEY ARE CAUGHT. 
I have told you various ways in which fishes are caught — as I 
went along — but now I want to tell you about the capture of the 
beautiful and wonderful creatures who live on the bottom of the 
sea, where lines, and nets, and harpoons, and all such things can- 
not reach. 
It is done by the Dredge. Here is the picture of one ; the 
common kind used in oyster catching. 
It consists — as you see — of a strong net, shaped like a purse, 
and fastened on to a strong iron frame. The bottom of the frame 
is flat, like a scraper, and a scraper it is, too. The whole machine 
is dropped over from a ship, and dragged along the ground for 
a while. Of course, anything before it, not too large to get in, 
must be drawn up, when at last they draw the Dredge up on deck 
and proceed to empty it.
