“That’s the talk!” The colonel gripped Dave’s hand for an instant, then was away.

When two hours later the Wanderer nosed her way out of the smooth water of the canal into the surging seas that swept Lake Superior, Dave caught his breath. Had he, for once, overestimated the cruising power of his stout little craft? Only time would tell. The Wanderer appeared to glory in its battle with the waters. Climbing one monstrous wave, it glided down the breaker’s slope, only to start climbing again. Great splashes of white spray were dashed against the pilothouse window. The deck was all awash; yet the Wanderer’s motors throbbed sweetly as the gallant boat forged its way ahead.

Night came. The storm increased. The black waves of night seemed more terrible than those of the day. Struggling into her little galley, Katie braced herself stiff-legged against a screwed-down table while she prepared sandwiches for the weary men.

Below deck, one of the twenty pumps, breaking its moorings, threatened to smash the others into bits. Only after many bumps and bruises was Rufus able to restore it to its proper place.

“Wi-wild night,” Dave’s words were blown down his throat as he reached gratefully for his sandwich.

“Tho-thought I saw a light,” Florence screamed.

“Sure! Sure! There it is!” Dave shouted. “Must be Passage Island. And boy, oh, boy! If it is, we’re right on our course!”

They were on their course. They had Indian John to thank for that. One peril still lay before them—the narrow, rocky entrance of Rock Harbor. Could they make it? There was a prayer in every heart as they neared the dark bulks looming out of the night.

“Little islands that guard the channel,” Dave explained, playing his ship’s light upon them. “They’re all solid rock. And you don’t see all of them. Some are just under the water. One touch on a night like this, and—

“There! There’s the gap!” he exclaimed excitedly. “It’s straight ahead of us, one marker to the right and one to the left. Thank God, the waves are striking the island squarely! We’ll ride them like a bucking broncho.
