is capable
of producing. I shall never forget the impatience with which I have
often watched the approach of darkness after a long day's run to the
south, knowing that, in a few moments, I was to discover celestial
phenomena heretofore concealed from my view.

After slanting through the north-east Trade-wind, we reached that
well-known but troublesome stage in the voyage, so difficult to get
over, called the Variables. This region has acquired its title from
the regular Trades not being found there, but in their place unsteady
breezes, long calms, heavy squalls, and sometimes smart winds from the
south and south-westward. These Variables, which sorely perplex all
mariners, even those of most experience, while they drive young ones
almost out of their senses, are not less under the dominion of the
causes which regulate those great perennial breezes the Trades,
blowing to the northward and southward of them. Their laws, however,
are not quite so readily understood, and consequently are not so
easily allowed for in the practice of navigation.

When we actually encounter, on the spot, and for the first time, a
crowd of new circumstances, of which, previously, we have only known
the names, or have merely heard them described by others, we feel so
much confused and bewildered, that we fly eagerly to the nearest
authority to help us out of the scrape. It generally happens, in these
cases, that the reference does not prove very satisfactory, because
the actual circumstances with which we are engaged are rarely similar
in all their bearings to those with which we compare them; and when
this is not the case, the blindfold method of proceeding in the beaten
path is very apt to mislead.

As an illustration of this kind of deception, it may be stated that
navigators, whose actual experience has not extended to the tropical
regions, are very apt, in poring over the voyages of others, to
acquire, insensibly, a very confident notion that each of the great
Trade-winds blowing on different sides of the Line (the North-east and
the South-east by name), are quite steady in their direction; and
that, in the equatorial interval which lies between them, only calms
and light winds are to be found. Moreover, inexperienced persons
generally believe this interval to be equally divided by the equator,
and that both the breadth and the position of this calm region
continue unchanged throughout the whole year. Now, here are four
important mista
