"Well, no one would ever say they were pretty," remarked Robert after a good look at them through the glasses. "We are catching up with them now. Hello, they've stopped."

In a short time the steam launch was abreast of the gasoline boat. In the latter but one man was to be seen, and an ill-favored man he was.

"My! What a brutal-looking fellow," remarked Nellie Strong with a shudder.

"What do you want?" demanded the man, in a surly, sullen way.

"We were stealing pilotage from you, that's all," replied Robert. "We're going up this river and don't know the channel and are afraid of going ashore. Is there danger of that if we keep in the middle of the stream?"

"I hope you'll strike a shoal and stay there till the crack of doom. You've no business to go running after another boat that way."

"What's the matter with you?" called out Robert; "and why don't your two friends show themselves? It looks to me as if you're afraid of the police."

The man made an angry exclamation and the steamer passed ahead. "What an ill-tempered man," said Helen Blunt to Robert; "I wish he'd cut off that red beard of his; he wouldn't look so much like a pirate then."

"We won't worry about that fellow. Now I'm going up in the bow with a boat-hook to take soundings; we'll run slow and keep right in the middle of the river. But isn't it beautiful around here. Just look how the little river twists and winds about and how irregular the shore is; and there are lots of little creeks running into the river and little bays stretching out from it."

"And isn't it lonely?" rejoined Helen. "There is hardly a house or a clearing to be seen; it's a regular wilderness."
