“Nerves!”

For a moment something like real panic seized the Motor Boys, and the impulse of each of them was to run. But they did not know which direction to take. Then, too, this sensation lasted but a few seconds before they had control of themselves again and the situation was well in hand.

“Do you really think we’re lost?” asked Jerry, in a whisper which in a measure defeated the echo, as only a faint murmur came back.

“I’m sure of it!” and Ned was equally careful about using loud tones. “This is where the echo is loudest, you remember, and it’s where I found the red rock. I thought it might be red gold, that I’ve heard can be found in some places, but as soon as I picked up the rock I found it was too light to be gold, so I chucked it away. But here we are back at the same place instead of being on our way out of the canyon.”

“That’s so,” agreed Bob. “But let’s get to some place where we can talk naturally without all those echoes butting in, and then we can decide what’s best to do. I’m glad I brought some sandwiches,” and he significantly tapped his bulging coat pockets on either side.

It was no time for Ned or Jerry to poke fun at the fat lad, and they held back any remarks that might have occurred to them.

“We may be lost a long time,” went on Chunky.

“Oh, I think we can soon find a way out of here,” Jerry replied.
