THE SHARKS OF NARBOROUGH 187 



through the water glass. Two sharks were swim- 

 ming slowly about the very rock where I had been 

 sitting a few minutes before, probably the same 

 individuals who had then been so curious about 

 me. A small group of the pigfish swam around, 

 over and below the sharks, as they had also done 

 when I was submerged, sometimes passing within a

 golden grouper together with two deep green 

 giants of the same species, milled around beneath 

 the boat, cocking their eyes up at us, now and then. 

 I baited the hook with a toothsome bit of crab and 

 lowered it. All the pigfish rushed it at once, and as 

 it descended, the sharks and groupers followed with

 attention from the golden grouper I allowed one 

 of the pigfish to take the bait and hook. Then, 

 watching very carefully, I checked his downward 

 rush, and swung him upward. He struggled fiercely

 neighborhood, yet gathered together in a group 

 and milled slowly in a small circle. There was no
