a cruiser
looking after slavers.

On the 6th of August we beheld, for the first time, flying fish, but
at such a distance that we could scarcely distinguish them.

On the 7th of August we neared the Canary Isles, but unfortunately,
on account of the thick fog, we could not see them. We now caught
the trade wind, that blows from the east, and is anxiously desired
by all sailors.

In the night of the 9-10th we entered the tropics. We were now in
daily expectation of greater heat and a clearer sky, but met with
neither. The atmosphere was dull and hazy, and even in our own raw
fatherland the sky could not have been so overcast, except upon some
days in November. Every evening the clouds were piled upon one
another in such a way that we were continually expecting to see a
water-spout; it was generally not before midnight that the heavens
would gradually clear up, and allow us to admire the beautiful and
dazzling constellations of the South.

The captain told us that this was the fourteenth voyage he had made
to the Brazils, during which time he had always found the heat very
easily borne, and had never seen the sky otherwise than dull and
lowering. He said that this was occasioned by the damp, unhealthy
coast of Guinea, the ill effects of which were perceptible much
further than where we then were, although the distance between us
was 350 miles.

In the tropics the quick transition from day to night is already
very perceptible; 35 or 40 minutes after the setting of the sun the
deepest darkness reigns around. The difference in the length of day
and night decreases more and more the nearer you approach the
Equator. At the Equator itself the day and night are of equal
duration.

All the 14th and 15th of August we sailed parallel with the Cape de
Verde Islands, from which we were not more than 23 miles distant,
but which, on account of the hazy state of the weather, we could not
see.

During this period we used to be much amused by small flocks of
flying-fish, which very often rose from the water so near the ship's
side that we were enabled to examine them minutely. They are
generally of the size and colour of a herring; their side fins,
however, are longer and broader, and they have the power of
spreading and closing them like little wings. They raise themselves
about twelve or fifteen feet above the water, and then, after flying
more than a distance of a hundred feet, dive down again for a moment
beneath
