"That," said O'Hara, "is the question."

"There's no doubt but they're traders," Gleazen muttered. "We'll have to fight before we reach the river. The more on our side, the merrier, I say, when it comes to fighting."

By our silence we assented.

Arnold raised his hand. "It is by surprise, gentlemen, or not at all. Are you ready?"

Breathing hard, we pressed closer together.

"Quickly, then! Together, and with speed!"

Arnold's voice snapped out the orders as if we were a company of military. There was something so commanding, so martial, in his manner and carriage, yet something that fitted him so well and seemed so much a part of his old, calm, taciturn, wise way, that I felt a sudden new wonder at him, a feeling that, well though I thought I had known him, I never had known him.

Then, brought all at once into action by the energy and force of his command, as was every one of the others, I started at the word as did they. Together we ran straight through the camp of sleeping blacks,—so strong was Matterson's spirit, so great his eagerness, that he now kept pace with us almost without help,—straight past the coals of their campfire, over the remnants of their evening meal, over their weapons and shields strewn in the road, and on toward their picket-line. As they woke behind us, bewildered, and groped to learn the cause of the sudden disorder, and realized what was happening, and started up with angry cries, we leaped, one after another, actually leaped, over a black sentry nodding at his post, over a frail barrier that they had thrown up to conceal their movements, and charged down upon a threatening stockade behind which lay the caravan.

That the caravan kept better watch than their besiegers, we learned first of all; for even as we leaped the barricade and came racing down the road, a gun went off in our faces and a cry of warning called the defenders from their sleep.

"Don't shoot!" O'Hara yelled. "We're white men! Don't shoot!"
