At this Ham Spink's eyes brightened. He was not above telling an untruth when he felt like it.

"What will you take for what you have?" he called out.

"What have you got?"

The rival campers looked over such provisions as they had left, and enumerated the articles—-sugar, cocoa, flour, some canned goods, and some preserves. Snap and his chums went ashore and investigated.

"We'll trade even," said Snap at last, after talking with his chums. "But on one condition."

"What is that?"

"That you take some letters home for us and deliver them as soon as you arrive."

"All right, we'll do that," said Carl Dudder.

The trade was made on the spot, and the letters written; and on the following morning Ham Spink and his cronies left the vicinity of Firefly Lake. It was the last our friends saw of the dudish youth and his friends for some time to come.

"I think he feels sick all over," remarked Shep, after the other crowd had departed.
