To any one unaccustomed to the sea the change thus wrought in the course of a few short minutes would have seemed marvellous, almost miraculous, indeed; for whereas while we were hove-to, head to wind and sea, the plunging of the ship had been so furious that it was only with the utmost difficulty even the most seasoned among us could maintain our footing; while the howling and shrieking of the wind aloft, and the savage force with which it struck us when the frigate rolled to windward, irresistibly suggested the idea that we were in the grip of a hurricane; now, when we were scudding away almost dead before it, the gale seemed to have suddenly softened to the strength of no more than a moderate breeze; there were no repetitions of those sickening lee lurches as the ship was flung aloft on the steep breast of a mountainous, swift-running sea, but, in place of it, a gentle, rhythmical, pendulum-like swinging roll, and a long, easy, gliding rush forward, with an acre of foam seething and hissing about our bows as those same steep, mountainous seas caught us under the quarter and hurled us headlong forward with our bow-wave roaring and boiling ahead of us, glass-smooth, and clear as crystal. There were but two drawbacks to our satisfaction, one of which was that the weather still remained so exasperatingly thick that we had not been able to get a further glimpse of the strange ship, while the other was that we only knew our position very approximately, and that by dead reckoning only. This last would have given us no concern at all had we been heading to the southward, for in that direction there was plenty of sea room; but we had now turned round and were rushing back northward-- north-north-east by compass, to be exact; and we knew that somewhere ahead of us--whether on the port or the starboard-bow we were not at all certain--were the terrible Penmarks; and, beyond them, the jutting Pointe du Raz, Douarnenez Bay, Pointe de Saint Mathieu, and the dangers that lurk between Ushant and the mainland, all bad enough in themselves, but with an added terror due to the furious currents that swirl round that part of the coast, and of the direction of which one can never be quite certain. That some such thoughts as these were disturbing the skipper's equanimity soon became apparent, for after pacing the deck thoughtfully for some time he suddenly looked up, and seeing me standing half-way up the poop-ladder, straining my eyes into the thickness ahead in a vain endeavour to get a glimpse of the chase, he called me to him. "Is it your watch, Mr Delamere?" said he. "No, sir," answered I, touching my hat, "but I thought I should like to get a sight of the fellow we're after before going below."
