“How? You can’t!”

“You watch me! Didn’t I take the prize at school for high trapeze work?” and Stumpy went on unlacing his shoes.

“Are you going to climb up in that cordage?” demanded Ned.

“That’s what I am.”

“We won’t let you!”

“It’s the only way!” said Fenn earnestly. “We may be killed if I don’t. There’s no danger boys. I’ll climb from the inside. If I fall, I’ll only fall into the basket! I’m going up!”

Before the others could stop him he had reached up and taken a firm hold of the cords just above the edge of the basket. They were very strong, and there were so many of them that they would have held a much greater weight than that of Fenn.

But it was a ticklish thing to climb up the netting of a balloon, more than half a mile above the earth. True, he was right over the basket, and if he slipped would land into it. But it was a daring thing to do, and his chums held their breaths as they watched him.

Up and up Stumpy went. His stockinged feet gave him a good purchase on the netting, and, clinging with his hands in a desperate grip, he mounted higher and higher toward where the caught cords dangled. It was only about ten feet but to Stumpy and his chums it seemed like a thousand.
