most of the sea-spiders were reddish. At this depth we got 

 the same fish as in the bay. A fish-trap, baited, was put 

 down at twenty-five fathoms. It caught some dozens of 

 pretty large big-heads the first time it was drawn, and 

 almost nothing afterwards, unless left for a considerable 

 time. This seems to indicate that they are pretty plenti- 

 ful, but that they grub very closely among the sponges 

 and don't travel fast or far, so that the first haul exhausts 

 the region immediately around the trap. When the trap 

 was brought up great red worms hung like ribbons, one 

 yard, or even two yards, below the trap. These could con- 

 tract until they would lie on the palm of the hand.
