CHAPTER XVIII.
THE TRIP TO YELLOWSTONE.
Everyone was up early the following day to watch the installing of the radio. With the exception of Bob and Arthur, who were always obliged to go out for the horses, no one did any riding that day.
Kirk and John did most of the work, while the others stood around, longing to be of some assistance and asking innumerable questions.
“Will it last till next summer if we should come back?” inquired Mae.
“You mean when you come back!” corrected Tom Melville. “For, of course, you’re coming.”
“I hope so,” answered John, smiling.
“How far do you think we can hear?” asked Bob. “San Francisco?”
“Probably. But surely Denver.”
“Not New York?” said Lily, in a disappointed tone. She had thought that once you possessed the instrument you could hear any sending station in the world.
“Hardly,” replied John. “It has to be a larger, more sensitive instrument to hear such distances. But I am sure you will listen in on lots of interesting things.”
