CHAPTER XVI
REMARKABLE GROWTH OF UNITY
"We haven't heard from John for two days. I wonder if they have met with any difficulties?" asked Will, as they were together the evening after their trip to the hill and forest.
"John is very prudent, and a man of very extensive knowledge as a campaigner. If they had met any disaster we should have known of it before this."
"We ought to have had a telegraph line. That would keep us in touch with the army," added Jim.
"Wireless telegraphy would be still better," responded Tom.
"But how about wireless telephones?"
"And if wireless telephones, why not wireless power?"
The Professor smiled, as one suggestion after the other was made. The other boys smiled, too, at Jim's last suggestion that power might be transmitted by wireless.
"That is going a little too far," said Will. "I can understand why sounds can be sent, but power is another thing, it seems to me."
