"On the 27th October, 1838, the Royalist left the river; and, after a succession of heavy gales, finally quitted the land on the 16th December. I may here state some farther particulars, to enable my readers to become better acquainted with her and her equipment. The Royalist, as already noticed, belonged to the Royal Yacht Squadron, which in foreign ports admits her to the same privileges as a man-of-war, and enables her to carry a white ensign. She sails fast, is conveniently fitted up, is armed with six six-pounders, a number of swivels, and small arms of all sorts, carries four boats, and provisions for four months. Her principal defect is being too sharp in the floor, which, in case of taking the ground, greatly increases the risk; but I comfort myself with the reflection that a knowledge of this will lead to redoubled precaution to prevent such a disaster. She is withal a good sea-boat, and as well calculated for the service as could be desired. "Most of her hands had been with me for three years or upward, and the rest were highly recommended. They are, almost without exception, young, able-bodied, and active--fit in all respects for enduring hardship and privation, or the more dangerous reverse of self-indulgence, and willing to follow the fortunes of the Royalist and her commander through all the various shades of good or evil fortune which may betide. A fine, though slow passage took us to Rio Janeiro, which presents features of natural beauty rarely equaled. The weather during our stay was hot in the extreme, and very wet, which marred, in some degree, the satisfaction I should otherwise have enjoyed in wandering about this picturesque country. I passed ten days, however, very agreeably, and departed with some regret from this brief visit to America and from my friends (if they will so allow me to call them) on board H.M.S. Calliope. I must not omit to mention that, during my stay, I visited a slaver, three of which (prizes to our men-of-war) lay in the harbor. It is a most loathsome and disgusting sight. Men, women, and children--the aged and the infant--crowded into a space as confined as the pens in Smithfield, not, however, to be released by death at the close of the day, but to linger, diseased and festering, for weeks or months, and then to be discharged into perpetual and hopeless slavery. I wish I could say that our measures tended toward the abolition of this detestable traffic; but from all that I could learn and observe, I am forced to confess that the exertions made to abolish slavery are of no avail in this country, and never will be till harsher means are resorted to.
