"Am I right or wrong, captain?" persisted the professor. "My information came from a naval man."

The commander's face became set and stern, as it usually did when he was serious. Removing his cigar, he said slowly:

"Your informant was right. For some reason or other, there is no such thing as an absolutely accurate chart of the Indian Ocean. They have talked for years of making a new chart, but, so far, nothing has been done. Yet we sailors who regularly navigate these waters know from experience that there are hereabouts currents strong enough to divert a vessel from her true course, and a number of small islands no mention of which is made on the existing charts. The Admiralty and Lloyds are well aware of the existence Of these dangers to navigation, but you all know what red tape is."

"How delightfully romantic!" cried Grace, with enthusiasm. "Unexplored islands inhabited by savages who never saw white people, and who trade in beads and go naked!"

"Cannibals, no doubt," suggested Mrs. Stuart, with an affected shudder.

"Where are these islands?" inquired Grace.

"A long way out of our course, I hope," laughed the captain. "Yet I've passed quite close to some of them. They seem quite deserted. So far as we could make out, there is not even animal life on them. But, being in the direct steamer lane to India, they constitute a menace to shipping that should be removed."

"Most decidedly—most decidedly!" said the professor emphatically.

Captain Summers arose to go.

"It's very delightful chatting here," he said, with a smile; "but I must go up on the bridge and attend to my duties. Otherwise, we may bump right on to one of those islands."
