Putting his bugle to his lips Rand blew a long, clear call, but it brought no response.
"Which way did the sound come from?" asked Gerald.
"From over that way," replied Dick, indicating with his hand.
"What would he be doing away off there?" demanded Donald.
"There is it again," said Gerald, as the sound was repeated.
"It is over this way," declared Jack, designating another direction.
"No, it's over this way," asserted Dick, but still at variance with the others.
"Wait," said Rand, "maybe we can hear it again."
The boys stood silent for a few moments, when the call came faintly once again.
"It is over this way," declared Rand, leading the way to the right, but, although they stopped from time to time to listen, they did not hear the sound again, nor did they find any trace of their missing comrade. For a half hour or more they continued their search, but in vain, and they were returning to the road when they heard the call again, but so faintly that it was lost almost as soon as heard.
