Rapidly the two walked back along the fire trail. "Charley," said the forester suddenly, "just how did you manage to get that message to Jim? It's all that saved the forest. The telephone was put as completely out of commission as your wireless was."

Charley then told the forester how he had used a tree for an aerial. "It was my last chance," he said. "If it hadn't worked, the forest would have burned. I had read about the use of trees to receive by, and I thought I had read that messages had been sent through trees, but I wasn't sure. It was my only chance and I took it."

"You're a wonder, Charley. I take back everything I ever said about the wireless. I have telegraphed for the Commissioner to come on from the capital. I shall put this entire matter before him and urge the installation of a wireless outfit in every district of the state forests. No matter what is done elsewhere, we're going on a wireless basis here as soon as we can get the outfit, just as I told you. If I can't get money from the state for the outfit, I'll pay for it myself and have your Wireless Club make it. This coming winter we'll start a radio school and you shall have charge of it. Maybe Jim can help you now."

"That will be grand," said Charley with sparkling eyes. "If only we had the money Lumley robbed the state of, we could buy a dozen outfits."

"We'll get every cent of it," said the forester with decision. "Don't you worry about that. When we went to the lumber camp after Lumley last night, I stopped all cutting. Before another stick is felled, you and I are going in there and measure every stump. Then we'll estimate the timber that came from those stumps and the lumber operators will pay for it or they will face a criminal prosecution. If we catch Lumley, we've got the operators dead to rights. He's the kind of a rat that will squeal quick when he's caught."

They reached the road, jumped into the forester's car and sped away to Lumley's house. Half an hour later they entered the forester's office, carefully carrying a window-sash. As the forester reached his desk, the man in charge handed him a message from the state police at Maple Gap. It read, "Have arrested three men who came out of the forest here and tried to board a train. They give fictitious names, but no doubt two of the men are wanted. Third has gold teeth and scar over right cheek. Do you want him?"

"Do we want him?" echoed the forester, as he began to write an answer. "Well, I should say we do."

He dashed off his message, and handed it to his assistant. "Rush that," he directed.

Then he took a long coil of wire from a closet and led the way back to his car. "That's for a temporary aerial in case you decide to make one," he said, as Charley climbed up beside him and they went whirling back to the fire-tower in the mountains.
