"You boys are the brakes," sang out Uncle Dick, almost as excited as the young people themselves. "When we shout for 'Brakes!' it is up to you twins to do your part."

"We will, sir!" cried Tommy and Teddy in unison.

"And don't hang your arms or legs over the sides," advised Uncle Dick. "Farewell, Jack! Take care of him, Mrs. Canary. And many, many thanks for a jolly time."

The boys and girls chorused their gratitude to the owner of Mountain Camp and his wife. The men behind gave the pung just the tiniest push. The runners creaked over the ice, and the forward end pitched down the slope. They had started.

And what a ride that was! It is not likely that any of them will ever forget it. Yet, as it proved, the danger was slight. They coasted the entire down-grade to the little railroad station where Fred Jaroth was telegraph operator with scarcely more peril than as though they had been riding behind the Jaroth horses.

But they were on the qui vive all the time. Bobby declared her heart was in her mouth so much that she could taste it.

There were places when the speed threatened disaster. But when Uncle Dick shouted for "Brakes!" the twins broke through the crust with their peaveys and the hook broke up the thick ice and dragged back on the pung so that the latter was brought almost to a stop. The handles of the peaveys were braced against the end staffs of the pung, and to keep them in position did not exceed the twins' strength.

Once Ted's peavey was dragged from his hands; but he jumped out and recovered it, and then, falling, slid flat on his back down the slippery way until he overtook the slowly moving pung again amid the delighted shouts of his chums.

Otherwise there were no casualties, and the pung flew past the Jaroth house a little before eleven to the great amazement of the whole family, who ran out to watch the coasting party.

"I don't know how Jonathan Canary will recover his pung," said Mr. Gordon when they alighted on the level ground. "But I will leave it in Jaroth's care, and when the winter breaks up, or before, it can be taken back to Mountain Camp.
