ground about eight miles from land. And then, 
again, they are away off on “Rocky Ground,” 
twenty miles or more off shore. Still, it is won- 
derful, when vision and other resources fail to place 
them, to try the judicious use of cod-liver. Again 
and again, when not a bird was in sight, and I was 
satished that they had gone off shore, as the boat 
sailed along I have tossed out now and then a piece 
of liver, squeezed into fragments. In the course of 
some ten minutes, a Petrel would be seen, hovering 
far astern, feasting greedily. Soon the supply was 
garnered, and the “‘ Mother Carey’s”’ followed up 
the wake of the boat. No matter how fast we 
sailed, the ever hungry bird soon caught up and 
flitted close about, as though begging for more. 
Not only one, but wore: and another, a Haglet, a 
Skua, and before long we had the usual company.

advise one not to expect too much, unless there is a 
likelihood that there is at least one Petrel within a 
few miles. The solution is, I take it, the acuteness 
of their vision that enables them to see others hover- 
ing and feeding at a far greater distance than we 
could descry them. 
These ocean birds seem to have some power of 
observation as to the weather. Fishermen had told 
me that Petrels flock before a storm, but it was long 
before I observed it for myself. At length, one 
afternoon in August, we were sailing in from the
