"Iroquois!" said the rangers promptly.
"Yes, but are they friendly or hostile?"
The question seemed to them absurd, but they answered very civilly that it was a signal of some sort which could only be interpreted by Indians, and that they had no doubt that it meant some sort of mischief to us.
"Men," I said quietly, "you are wrong. That stone leaning upon a tree is a friendly message to me from a body of our Oneida scouts."
They stared incredulously.
"I will prove it," said I. "Jack, go you to that stone. On the under side you will find a number of white marks made with paint. I can not tell you how many, but the number will indicate the number of Oneidas who are scouting for us ahead."
Utterly unconvinced, yet politely obedient, the blond giant strode off across the road, picked up the great stone as though it were a pompion, turned it over, uttered an exclamation, and bore it back to us.
"You see," I said, "twenty Oneida scouts will join us about two o'clock this afternoon if we travel at the same rate that we are traveling. This white circle traced here represents the sun; the straight line the meridian. Calculating roughly, I should set the time of meeting at two o'clock. Now, Jack, take the stone to the stream yonder and scrub off the paint with moss and gun-oil, then drop the stone into the water. And you, Tim Murphy, go quietly among the men and caution them not to fire on a friendly Oneida. That is all, lads. We march in a few moments."
The effect upon the rangers was amusing; their kindly airs of good-natured protection vanished; Mount gazed wildly at me; Tim Murphy, perfectly convinced yet unable to utter a word, saluted and marched off, while Elerson and the Weasel stood open-mouthed, fingering their rifles until the men began to fall in silently, and I put up Elsin and mounted my roan, motioning Murphy and Jack Mount to my stirrups.
"Small wonder I read such signs," I said. "I am an Oneida chief, an ensign, and a sachem. Come freely to me when signs of the Iroquois puzzle you. It would not have been very wise to open fire on our own scouts."
