"Looney again," was the guard's comment which Frank heard. "Come on back to your room."
"I must try again," Frank said softly to himself as he hurried across the open space and into the woods once more. "I am on the right track!"
The boy made his way to where he had left the canoe. His mind was in a whirl at the scene he had just taken part in, and his heart, that had been filled with hope, was a little sad now at his failure. Still he had not given up.
"I'll go back to camp," he thought. "Then I can try again. I must have more time to talk to him, and we must get a chance when there will be no danger of interruptions. I will come again, but I must think up a new plan."
Then, setting the canoe into the water, he began to paddle back. Though it was approaching midnight he decided he would keep on, and get back to camp by morning.
CHAPTER XXI
FRANK LEAVES AGAIN
Frank reached camp in time for breakfast. He was weary with his long night journey, and his chums saw evidences of the strain it had been on him in his eyes, heavy from need of sleep, and his arms, which trembled from the long paddling. But they did not question him.
"Here's some hot coffee!" called Fenn, as his chum drew the boat up on the bank.
"Thanks," replied Frank. "I think I'll go to bed if you fellows don't mind. I'm dead tired."
"We're going off fishing," said Bart. "You can do as you please, and lie around all day."
