"Oh, there needn't be any difficulty about that. A button will do quite as well."
And with this Harry cut one of the buttons from his trousers.
"This will do," said he. "The face of the button will be 'head,' and the back of it 'tail.' And now, will you try it?"
He handed it to Ashby, who took it without a word.
"If it falls 'heads,' the first fire will be yours; if 'tails,' the first fire will be mine."
"Very well," said Ashby; and then, poising the button for a moment, he tossed it.
It fell, head uppermost.
"Heads!" said Harry. "Mr. Ashby, the first fire belongs to you. Here's the pistol. It's loaded. I'll take my position here. Shall I measure the distance?"
"Pardon me, Mr. Rivers," said Ashby; "but I cannot accept this from one throw. It must be the best out of three times."
"I don't see why."
