In this employment our voyage, upon my part at least, passed unperceived, and I was at Liverpool, before I was well sensible that I had left America. Nothing is more tedious than a sea voyage, age, to those whose minds, are intent only upon their passage. In travelling by land, the mind is recreated by variety, and relieved by the novelty of the successive objects which pass before it; but in a voyage by sea, it is inconceivable how wearisome are the sameness and uniformity, which, day after day, meet the eye. When I could not otherwise occupy my mind, I endeavoured to force myself into a doze, that I might have a chance of a dream. One of the best rules of philosophy is, that happiness is an art--a science--a habit and quality of mind, which self-management may in a great degree command and procure. Experience has taught me that this is true. I had made many sea voyages before this, and therefore had repeated proofs of the observation of Lord Bacon, that, of all human progresses, nothing is so barren of all possibility of remark as a voyage by sea; nothing, therefore, is so irksome, to a mind of any vigour or activity. If a man, by long habit, has obtained the knack of retiring into himself--of putting all his faculties to perfect rest, and becoming like the mast of the vessel--a sea voyage may suit him; but to those who cannot sleep in an hammock eighteen hours out of the twenty-four, I would recommend any thing but travel by sea. Cato, as his Aphorisms inform us, never repented but of two things; and the one was, that he went a journey by sea when he might have gone it by land. The sight of land, after a long voyage, is delightful in the extreme; and I experienced the truth of another remark, that it might be smelt as we approached, even when beyond our sight. I do not know to what to compare its peculiar odour, but the sensations very much resemble those which are excited by the freshness of the country, after leaving a thick-built and smoky city. The sea air is infinitely more sharp than the land air; and as you approach the land, and compare the two, you discover the greater humidity of the one. The sea air, however, has one most extraordinary quality--it removes a cough or cold almost instantaneously. The temperance, moreover, which it compels in those who cannot eat sea provisions, is very conducive to health.
