A half hour he kept on without faltering, always with the intention of reaching the shores of the island and skirting it until he could discover the lagoon. And always his companion continued silent.

When he had time to think, Allan concluded that she had fallen asleep and was grateful.

If he could not get in to shore he was managing not be driven far out of the course.

At midnight the small steamboat would call at the island to take the guests back to the mainland, who were not to spend the night, and with luck he might be able to signal them.

"Don't you think you had better rest for a few moments, Mr. Drain?" A quiet voice suggested. "Please don't be worried, I am not uneasy. At the worst, if we cannot reach the lagoon and no boat comes to our rescue, we shall only drift about until the tide turns. When daylight arrives we shall have no difficulty. I hate your wearing yourself out and wish I could help."

Gill laughed, a more courageous, gayer laugh than he had heard from her since their earlier acquaintance.

"Why, you did not think I was asleep? I am not so stupid as all that! I did not wish to trouble you by talking."

Compelled to follow Gill's advice, resting his oars, Allan allowed their boat to move with the tide. Another half hour went by; at length both of them appreciated that it must be well past midnight and there was little chance of rescue by their friends. The small steamboat crossed directly from the island to the mainland and made no circuit of the bay.

Without comment Allan picked up his oars again.

"I think I can manage to reach the island, even if we do not discover the lagoon before dawn. I have walked around the island several times and there are a number of places where one can land. We will be more comfortable than in this cramped little boat and warmer. Besides we are in some danger with the waves growing higher and stronger and the night darker. I am not going to attempt to disguise the fact from you, you are as courageous as I am, in truth you are more courageous as I remember you. If you wish to have the score settled with me in regard to the accidental burning of my manuscript, I have accomplished it with a vengeance to-night by bringing you out on the water and getting you into this difficulty. I only hope you may not be ill again as a result of my stupidity. But I must not talk, I have no breath to spare. Once we are safe and ashore I'll offer my apology."
