"Not a dragline or a clamshell," Scotty said. "We certainly didn't make much of a dent, did we?"
"At this rate we'll be here until Christmas," Rick said.
"Not that we'll need a Christmas tree."
"We could use the lights," Rick commented. "Let's keep plugging. I'm not so sure I need a rest after all."
"Might as well."
"Just sitting on the rocks will sap our strength, anyway," Rick pointed out. "We might as well work while we're still fresh. We can take five-minute breaks when we begin to tire."
"I'm with you. Tote those rocks."
"Let's use one light, too. No point in just clearing the tunnel. We want to break through in as short a time as possible. If we use the light we can pull rocks from nearer the top of the slide."
"Sensible as usual. I'll prop my light so it shines on the slide."
Scotty did so, then both boys shed their shirts once more.
