“It is impossible at present to say anything definite about her, sir,” I answered. “I saw her but for a second, and then only very indistinctly, but she loomed up through the fog like a craft of about our own size.”

“Very well, sir,” answered Hennesey; “stay where you are, and keep a sharp lookout for her next appearance.”

Once more I returned the stereotyped, “Ay, ay, sir!” as I sent my glances searching round the ship for further openings. The next that overtook us swept down upon our port quarter; it was fully a mile and a half wide, and when it bore about four points abaft the beam another shape slid into it, not vague and shadowy this time, as the other shape had been, but clearly distinct—a frigate, unmistakably, under a similar spread of canvas to our own, and as nearly as possible our own size. So close indeed was the resemblance that for a second or two I was disposed to fancy that by some strange trick of light and reflection the fog was treating me to a picture of the old Althea herself, but a more steadfast scrutiny soon dispelled the illusion. There were certain unmistakable points of difference between this second apparition and ourselves, some of which were so strongly characteristic that I at once set her down as a French frigate.

The plot was thickening, and it was not wholly without a certain feeling of exhilaration that I again hailed the deck—

“A frigate broad on our port quarter, sir, with a very Frenchified look about her!”

“Thank you again, Mr Courtenay,” answered Hennesey, with an unmistakable ring of delight in his jovial Irish accent, which, by the way, had a trick of growing more pronounced under the influence of excitement. “Ah, true for you, there she is,” he continued, “I have her! Mr Hudson, have the kindness to jump below and fetch me my glass, will ye, and look alive, you shmall anatomy!”

A gentle ripple of subdued laughter from the forecastle at this sally of our genial “second” floated up to me from the forecastle, a glimpse of which I could just catch under the foot of the fore-topsail, and I could see that the men were all alive down there with pleasurable excitement at the prospect of a possible fight. Young Hudson—a smart little fellow, barely fourteen years old, and the most juvenile member of our mess—was soon on deck again with the second lieutenant’s telescope; but by this time the fog had shut the stranger in again, so, for the moment, friend Hennesey’s curiosity had to remain unsatisfied. Not for long, however; the presumably French frigate had not been lost sight of more than two or three minutes when I caught a second glimpse of the other craft—the one first sighted—on our starboard quarter.

“There is the other fellow, sir!” I shouted. “You can see her distinctly now. And she too is a frigate, and French, unless I am greatly mistaken.”

“By the powers, Mr Courtenay, I hope you may be right,” answered Hennesey. “Ay, there she is,” he continued, “as plain as mud in a wineglass! And if she isn’t French her looks belie her. Mr Hudson, you spalpeen, slip down below and tell the captain that there are a brace of suspicious-looking craft within a mile of us. And ye may call upon Misther Dawson and impart the same pleasant information to him.” Then, turning his beaming phiz up to me, he continued—

“Mr Courtenay, it’s on the stroke of eight bells, but all the same you’d better stay where you are for the present, until the fog clears, since you know exactly the bearings of those two craft. And I’ll thank ye to keep your weather eye liftin’, young gentleman; there may be a whole fleet of Frenchmen within gun-shot of us, for all that we can tell.”
