These hints will apprise the reader that the greatest care, compatible with safety, is taken of a negro's health and cleanliness on the voyage. In every well-conducted slaver, the captain, officers, and crew, are alert and vigilant to preserve the cargo. It is their personal interest, as well as the interest of humanity to do so. The boatswain is incessant in his patrol of purification, and disinfecting substances are plenteously distributed. The upper deck is washed and swabbed daily; the slave deck is scraped and holy-stoned; and, at nine o'clock each morning, the captain inspects every part of his craft; so that no vessel, except a man-of-war, can compare with a slaver in systematic order, purity, and neatness. I am not aware that the ship-fever, which sometimes decimates the emigrants from Europe, has ever prevailed in these African traders. At sundown, the process of stowing the slaves for the night is begun. The second mate and boatswain descend into the hold, whip in hand, and range the slaves in their regular places; those on the right side of the vessel facing forward, and lying in each other's lap, while those on the left are similarly stowed with their faces towards the stern. In this way each negro lies on his right side, which is considered preferable for the action of the heart. In allotting places, particular attention is paid to size, the taller being selected for the greatest breadth of the vessel, while the shorter and younger are lodged near the bows. When the cargo is large and the lower deck crammed, the supernumeraries are disposed of on deck, which is securely covered with boards to shield them from moisture. The _strict_ discipline of nightly stowage is, of course, of the greatest importance in slavers, else every negro would accommodate himself as if he were a passenger. In order to insure perfect silence and regularity during night, a slave is chosen as constable from every ten, and furnished with a "cat" to enforce commands during his appointed watch. In remuneration for his services, which, it may be believed, are admirably performed whenever the whip is required, he is adorned with an old shirt or tarry trowsers. Now and then, billets of wood are distributed among the sleepers, but this luxury is never granted until the good temper of the negroes is ascertained, for slaves have often been tempted to mutiny by the power of arming themselves with these pillows from the forest.
