He listened with great interest a few days later when Mr. Tredgold, after considering audibly which island he should visit first, gave him the position of Bowers's Island and began to discuss coral reefs and volcanic action. They were now well in among the islands. Two they passed at a distance, and went so close to a third—a mere reef with a few palms upon it—that Mr. Chalk, after a lengthy inspection through his binoculars, was able to declare it uninhabited.

A fourth came into sight a couple of days later: a small grey bank on the starboard bow. Captain Brisket, who had been regarding it for some time with great care, closed his glass with a bang and stepped up to Mr. Tredgold.

"There she is, sir," he said, in satisfied tones.

Mr. Tredgold, who was drinking tea, put down his cup, and rose with an appearance of mild interest. Mr. Stobell followed suit, and both gazed in strong indignation at the undisguised excitement of Mr. Chalk as he raced up the rigging for a better view. Tredgold with the captain's glass, and Stobell with an old pair of field-glasses in which he had great faith, gazed from the deck. Tredgold was the first to speak.

"Are you sure this is the one, Brisket?" he inquired, carelessly.

"Certainly, sir," said the captain, in some surprise. "At least, it's the one you told me to steer for."

"Don't look much like the map," said Stobell, in a low aside. "Where's the mountain?"

Tredgold looked again. "I fancy it's a bit higher towards the middle," he said, after a prolonged inspection; "and, besides, it's 'mount,' not 'mountain.'"

Captain Brisket, who had with great delicacy drawn a little apart in recognition of their whispers, stepped towards them again.

"I don't know that I've ever seen this particular island before," he said, frankly; "likely not; but it's the one you told me to find. There's over a couple of hundred of them, large and small, knocking about. If you think you've made a mistake we might try some of the others."
