Not many steamers stop at the Soo, save those which run in connection with the tourist travel, between Mackinac and the rapids city. But there is a constant procession of steamers, and whaleback grain barges going in both directions, day and night, all during some seven months of the year. The tonnage of the government canal through which these boats pass around the rapids far exceeds that of the Suez Canal for the entire twelve months.

After finding a responsible party in whose charge the three brave little boats could be left, the cruisers proceeded to take in the sights.

Of course the rapids came first, and they viewed these from every angle. Jack was also deeply interested in the government fish hatchery on the little island; and watched with an envious eye the various pools in which scores of enormous speckled trout, weighing upward of seven pounds, were kept.

“Wait till we get to the Agawa,” he said, shaking his head with determination. “I want to find out how some of those whoppers feel at the end of a line.”

Nick had made for a clothing emporium, where he fitted himself out in some new clothes. Of course he did not explain just why this was necessary; but judging from the suspicious looks cast upon him every time he came near the clerk, the latter could give a shrewd guess concerning the truth.

Jack was still watching some of those giant trout jump out of the water in the pool when he dangled a long blade of blue grass so as to make the feathery end touch the surface like a fly, when George joined him; for they had settled upon the hatchery as a sort of rendezvous where they could come together, so as to take the thrilling ride down the rapids in a big Indian canoe.

“All off, Jack!” said George, trying to look sober; though there was a merry twinkle in his black eyes that belied the solemn cast of his face.

“What do you mean?” asked the other. “Anything more happened to that fellow Buster? Or perhaps it’s Josh who’s bent on halting our expedition now, with some caper. Go on, tell me.”

“Oh! you’re away off,” grinned George. “I only meant to inform you that they’re gone on ahead of us.”
