“Now, supposing the tide from the Pacific runs into Providence Beach a few minutes earlier than it reaches Nelson Straits, that would account for the terrific rush in which we were caught. For the same cause, the falling tide should be far less strenuous here, but stronger there, and I do really believe that opposite our camp the ebb tide always developed a swifter current than the flood.”

“I’m sure of it,” agreed Sturgess. “They were both pretty hefty, but this morning’s flood didn’t begin to compare with last night’s ebb. You ought to know. You went through it alone on board the raft.”

“Then the answer is, ‘Go forward,’” said Madge.

“I think so. Let us be guided by events. We have the best part of the day before us. Surely we can find some safer lodgment than this before night falls.”

The others knew that Maseden’s voice had lost its confident ring, but the fact that they had so narrowly dodged death barred all other considerations.

In his heart of hearts he was deadly afraid that they might indeed be compelled to return to Hanover Island. The sheer barrenness of the islet on which they were now stranded was its vital defect. Probably they would still find shell-fish, still knock an occasional seal on the head, but wood they must have, both for fire and raft building, and it seemed to him that there were no trees nearer than the slopes facing Providence Beach.

However, having come so far, they might at least have a look at the conditions on the south side, where lay yet another island; and there was also the unalterable fact that if they must escape by using the tides, their first day’s experiences, though resulting in disaster, had brought them many miles in the right direction.

Perhaps they had met and conquered their greatest danger. They had paid a dear price for victory, but that was nothing new in war.

Of course there was a long and wearisome wait before they could do other than sit on the slowly emerging rocks. But it was something gained when they were free to climb out into the open and see the sky over their heads. The silent, nerve-racking menace of the canopied rock was quite as unbearable as the loud-mouthed threats of sea and reef.

Madge, slightly less self-contained than her sister, promptly voiced her relief.
