"To-night is soon enough," he replied. "It's time for lunch now."

They reached the Stevens house late in the afternoon. The place was well-secluded in the thick woods; an ideal spot to remain undiscovered. The house contained old furniture; they arranged the beds with sheets and blankets that they had bought at Stevens's store.

"What next?" asked Bruce.

"Come with me," replied Harry.

He went to the back of the coupe and opened it. Within was a large box which Harry unlocked. Lifting the lid and taking out an inner covering, he revealed a complete radio apparatus — the most compact mechanism that Duncan had ever seen.

"Know anything about wireless telegraphy?" questioned Harry.

"Not much," admitted his companion. "I studied the International code and can send messages slowly, but I never went in for radio very strongly."

"I know a good bit about it?" said Harry. "This is one of the simplest sending sets ever devised. It has remarkable mechanical improvements. You can help me put up the aerial. I'll do the rest."

The two men completed the work at dusk. The night was cool at this altitude. They sat before a fire in the main room on the first floor, with the sending equipment and the receiving set close by.

"We'll cook some dinner," said Harry. "Then we can make our last investigation. After that we send out information. Fellows said that the Monday night report would be most important."
