"Barbican is floating midway in the depths of the Pacific, like Mahomet in his coffin!"

Blindly yielding, however, to the melancholy hope that is born of despair, Marston and his friends renewed the search next day, the 30th, but they were all too worn out with watching and excitement to be able to continue it longer than a few hours. After a night's rest, it was renewed the day following, the 31st, with some vigor, and a good part of the ocean lying between Guadalupe and Benito islands was carefully investigated to a depth of seven or eight hundred feet. No traces whatever of the Projectile. Several California steamers, plying between San Francisco and Panama, passed the Susquehanna within hailing distance. But to every question, the invariable reply one melancholy burden bore:

"No luck!"

All hands were now in despair. Marston could neither eat nor drink. He never even spoke the whole day, except on two occasions. Once, when somebody heard him muttering:

"He's now seventeen days in the ocean!"

The second time he spoke, the words seemed to be forced out of him. Belfast admitted, for the sake of argument, that the Projectile had fallen into the ocean, but he strongly denounced the absurd idea of its occupants being still alive. "Under such circumstances," went on the learned Professor, "further prolongation of vital energy would be simply impossible. Want of air, want of food, want of courage—"

"No, sir!" interrupted Marston quite savagely. "Want of air, of meat, of drink, as much as you like! But when you speak of Barbican's want of courage, you don't know what you are talking about! No holy martyr ever died at the stake with a loftier courage than my noble friend Barbican!"

That night he asked the Captain if he would not sail down as far as Cape San Lucas. Bloomsbury saw that further search was all labor lost, but he respected such heroic grief too highly to give a positive refusal. He consented to devote the following day, New Year's, to an exploring expedition as far as Magdalena Bay, making the most diligent inquiries in all directions.

But New Year's was just as barren of results as any of its predecessors, and, a little before sunset, Captain Bloomsbury, regardless of further entreaties and unwilling to risk further delay, gave orders to 'bout ship and return to San Francisco.

The Susquehanna was slowly turning around in obedience to her wheel, as if reluctant to abandon forever a search in which humanity at large was interested, when the look-out man, stationed in the forecastle, suddenly sang out:
