The Boxer, having orders to proceed on a voyage to Liberia and from thence to join the Peacock off the coast of Brazil, left Boston harbour about the middle of February, 1832; and on the following March we sailed from the same port, in the latter-named vessel, for Rio Janeiro; having on board F. Baylies, Esq., whom we were carrying to that place on his way to Buenos Ayres, to which Republic he had received the appointment of chargé d’affaires from the government of the United States. No circumstance, worthy of record, occurred until the eighth day of April, when at daybreak we discovered the isle of Sal, one of the Cape de Verds, and ere evening closed, St. Nicholas and Bonavista appeared in sight. We lay to on that night under the lee of Mayo and on the following morning cast anchor in the roadstead of Porto Prayo, in the island of St. Jago. The customary salute of thirteen guns, given to the town, was immediately returned with a corresponding number. Of the weather, considering the season, we had no reason to complain. The thermometer ranged between 40° and 72°, rarely exceeding the one or falling below the other; the lowest point, when we passed St. George’s Bank, being 37°, and the highest, at the time the northeast tradewind first met us, being 71°, in latitude 19°, and longitude 26°. The barometer ranged from 29°, 97′, to 30°, 45′. The most perfect order and regularity prevailed on board the ship, in every department of duty; each individual having his duties so defined as to prevent confusion among the crew, should any of the seamen be called suddenly to quarters, or to make, take in, or reef sails. Among the acquisitions most useful and instructive, were an excellent library, presented by the government to the officers, and a second selection of books, purchased by the officers and crew, jointly. It was a gratifying sight to behold men who might, otherwise, have been occupied in relating idle stories, singing immoral songs, quarrelling, or creating a mutinous spirit among their fellows, drawing useful information from the great sources of knowledge, and extracting from the page of history, at the same time, a fund of information and a code of morals. The Cape de Verd islands belong to the kingdom of Portugal, and are ten in number. They were discovered by Noel, in the year 1440, and contain a population, as follows: Sal, four hundred; Mayo, two thousand five hundred; St. Vincent, three hundred and fifty-six; St. Nicholas, five thousand; St. Jago, thirty thousand; Fogo, ten thousand; St. Antonio, twenty-four thousand; Brava, eight thousand; Bonavista, four thousand; St. Lucia, uninhabited; total, eighty-four thousand.
