As the long shadows came creeping across the river Peter no longer felt the fear which had made his heart beat so uncomfortably fast. His father's presence and the touch of his hand filled him with an utter confidence. The man even pointed out to him the mysteries of an ant home which they had accidentally destroyed in the log, and told him a story of how once upon a time he had gone down a flooded stream like this, and what fun it had been.
Then the shadows came more swiftly. The sun at last left only a golden glow above the forest. The blue jay and the sapsucker were gone. Out of the woods came the melodious dusk song of many red squirrels. A flock of crows sailed overhead on their way to the evening roosting place. The rush of the river seemed more gentle and lost its menace for Peter. The churning turmoil of the distant rapids was mellowed in a soft mist, and a little later they could not make out clearly the driftwood going down with the stream.
"Now is our time," said Peter's father. "Creep after me, flat on your stomach."
It took them only a minute to reach the big dry log. They could move freely here, for the upward dip of the bank concealed them. Donald McRae did not let Peter guess the tension he was under as he worked. He stood his rifle where the police would easily find it and laughed softly as he tied one end of a stout leather thong about Peter's wrist and the other end about his own. After that he rolled the log into the water and tested it to get its proper balance and tied the other leather thongs to a projecting stub.
"It's just right," he announced cheerfully. "A canoe couldn't have been better built for us, Peter. Are you ready?"
"I'm ready," said Peter.
He was in the water to his knees; now he went in to his waist. It was cold, biting cold; his teeth clicked, but he did not say anything about it. He looped his arms about the stub and through one of the leather thongs, and from the opposite side of the log his father twisted the fingers of one hand tightly in his coat. Then they began to move. His feet lost bottom and the cold water shot up to his armpits, taking his breath away. His father grinned cheerfully at him and he tried to grin back. In a moment they were in the current and the shore began to slip past them with amazing swiftness. It was not unpleasant, except for the icy chill of the water, which seemed to take the place of blood in his veins. There was no resistance against his body; the log carried them buoyantly and smoothly, so that after a little he had courage to look about him.
Their log had swung quickly into mid-stream, and they were overtaking a more slowly moving mass of driftwood. The thought came to Peter that it was like a race. Then something alive caught his eyes on the flotsam. It was a furry, catlike creature with short, perky ears and a fox's face, and he could almost have touched it with his hands when they passed.
"A fisher-cat," said his father. "He will have a nice swim when he hits the rapids!"
Peter was wondering just how much of a chance the fisher-cat had when something drifted against him. It was a drowned porcupine, floating belly up. The porky must have had a nice swim, too!
