"This place will do," said a voice.
"Yes, the leeward side is best."
"I wonder if the trigger will act?"
"I am sure it will."
"We were to let it off at ten, were we not?"
"Yes, at ten sharp. We have eight minutes yet." There was a pause. Then the voice began again—
"They'll hear the drop of the trigger, won't they?"
"It doesn't matter. It will be too late for any one to prevent its going off."
"That's true. There will be some excitement among those we have left behind, won't there?"
"Rather. How long do you reckon it will be before they hear of us?"
