But the Bradys were cheered up wonderfully.
They kept on shouting, and the track-walker finally found them by being guided by the tones of their voices.
Only their heads stuck above the water.
He stared at the pair in astonishment a moment, and cried:
"What in thunder are you doing in there?"
"Buried in quick-sand!" gasped Harry. "Help us—quick!"
The old fellow was startled and rushed in among the trees.
For a minute the detectives thought he deserted them. But he soon reappeared with a sapling he had cut with his pocket-knife.
Standing on the embankment, he reached out the end to Old King Brady, who lifted his hands above the water and grasped it.
"Pull!" gasped the detective.
