"Can't say I do, miss."
"Then I'll show you."
This was the work of a moment. The old bush-woman was handy enough, and cool enough too, now that she was getting used to the situation. It was her own idea to bring round the storekeeper's tall stool, to plant it among the props, within reach of Naomi on the boxes and of Engelhardt on the flour-bag, and to perch herself on its leather top with the box of cartridges in her lap. Thus prepared and equipped, this strange garrison waited for the next assault.
"Here they come," cried Naomi at last, with a sudden catch in her voice. "They're carrying a great log they must have fished out from the very bottom of the wood-heap. All the top part of the heap was small wood, and I guess they've wasted some more time in hunting for the axe. But here they are!" She pushed her revolver through the slit in the roof, and the sharp report rang through the store.
"Hit anybody?" said Engelhardt next moment.
"No. They're stopping to fire back. Ah, you were right."
As she spoke there was a single report, followed by three smart raps on the sloping roof. The bullet had ricochetted like a flat stone flung upon a pond. Another and another did the same, and Naomi answered every shot.
"For God's sake take care!" cried the piano-tuner.
"I am doing so."
"Hit any one yet?"
