In the evening we thought we descried Cape Blanco[A5], and according to the instructions given by the Navy Office, we steered W.S.W. During a part of the night the _Echo_, with which we had constantly kept company since we left Madeira, burnt several charges of powder and hung a lanthorn at the mizen-mast; her signals were not answered in the same manner; only a lanthorn was hung for a few moments to the fore-mast; it went out soon after, and was not replaced by another light. M. Savigny was on deck where he remained a part of the night: he had full opportunity to perceive the negligence of the officer of the watch, who did not even deign to answer the signals made by the _Echo_[A6]. Why, in the neighbourhood of so formidable a danger, not compare the points of the two ships, as is usual when vessels sail in company? The captain of the frigate was not even informed of the signals of the corvette. At eleven o'clock, she bore off the larboard bow; and soon after he perceived that the direction of her course made a pretty large angle with ours, and that it tended to cross us passing a-head; he soon perceived her on the starboard: it is affirmed that her journal states that she sailed the whole night W.S.W. ours does the same. We must necessarily have hauled to the larboard, or she to the starboard, since at day-break the corvette was no longer in sight. At sea a vessel may easily be perceived at the distance of six leagues. From midnight till six in the morning, she must have gained above six leagues of us, which is not to be imagined, for she sailed much slower than we and stopped every two hours to take soundings. To explain this separation we must necessarily admit either that the frigate steered more south, or the corvette more west, if the two vessels had run on the same tack it would be impossible to explain it.
