t was late in April, as we were stealing slowly past these distant
Canary Islands, when the first real puff of the Trade-wind caught our
sleeping sails, and made the braces, haulyards, and all the other
ropes connected with the yards, crack again. This breeze served more
effectually to detach our thoughts from European interests than
anything which had occurred since our leaving England. At the very
moment, however, when we were chuckling at this disentanglement of our
feelings from domestic anxieties, and all the varied agitation of home
concerns, we observed a ship crossing our path at some distance.
Signal being made to chase, we instantly darted off from the convoy to
examine the stranger, which proved to be an English ship from Lisbon.
We hailed, and asked, "What news?"

"Badajoz has fallen," replied the other, "after a terrible siege."

This was received with a general buzz of joyous congratulation along
the decks. In answer to further questions, we were told of some three
or four thousand men killed and wounded in the trenches and breach.
Then, indeed, the glorious intelligence was greeted by three jolly
huzzas from every ship in the convoy!

Nothing so startling as this occurred to us again; but the serenity of
our thoughts was in some degree interrupted, a few days afterwards, by
the north-easterly Trade-wind dying away, and a gentle south-wester
springing up in its place. This occurred in latitude 25-1/2 deg. N.,
where, according to our inexperienced conception of these singular
winds, we ought to have found a regular breeze from the very opposite
quarter! Nor was it till long afterwards that I learned how much the
force and direction of the Trade-winds are liable to modification by
the particular position which the sun occupies in the heavens; or how
far the rotatory motion of the earth, combined with the power which
the sun possesses of heating certain portions of the circumambient
air, are the regulating causes of the Trades, Monsoons, and, indeed,
of all the other winds by which we are driven about. It is by no means
an easy problem in meteorology to show how these causes act in every
case; and perhaps it is one which will never be so fully solved as to
admit of very popular enunciation applicable to all climates. In the
most important and useful class of these aerial currents, called, _par
excellence_, and with so much picturesque truth, "the Trade-winds,"
the explanation is not difficult. But before en
