smaller fishes could be traced by running lines; while now and then the movement of some monster caused the gleaming light to extend many fathoms in every direction.
After passing the Canary Islands, we cruised for reefs and sunken rocks, reported as being in this quarter, the squadron sailing in open line. Good lookouts were kept at the mast-heads, and soundings were taken with three hundred fathoms of line every half-hour, but no bottom was discovered. There was sufficient swell to cause breakers on any shoal which rose to within fifteen feet of the surface of the water. We sailed over the locality without perceiving anything that looked like shoal, rocks, or reefs. On the morning of the 7th of October we came to anchor off the town of San Jago, on one of the Cape Verde Islands. They were discovered in 1460 by the Portuguese, and are still subject to Portugal. They form a group of twenty islands, and are sparsely inhabited. The land is all mountainous, with scarcely enough vegetation to support the people and their cattle.

The most fatal of these famines occurred in the
