The idea struck Harry as a good one; so it was agreed that he should keep to the straight road while Gordon covered the loop. They had not traveled to this point, where they were now to part for an hour or so, without keeping a keen watch for any signs of the troop which the roadside might reveal. But an afternoon shower had obliterated any tracks, if such there were, and the road had yielded no hint of those who had gone before. But Harry, still hopeful despite the gathering dusk, now took his way alone, making careful scrutiny of the right-hand border of the road for any intentional signs that might have been left, although he had no reason to anticipate finding any.
The two boys were to meet where the roads again came together, which was at the foot of Dibble Mountain about two miles ahead, their plan being to camp somewhere under the shadow of the mountain and to climb to the summit in the morning for a bird’s-eye view of the surrounding country.
The light was fast fading as Gordon left his companion and started along the loop road. It was instinctive with him to keep his eyes wide open, and his training as a scout, under Harry’s special tutelage, had developed this trait until it was said of him by his friends, and especially by Red Deer, that his habit of finding things, of picking up pennies, collar buttons, and so forth, was little less than uncanny. His pockets were a veritable junk shop of miscellaneous trifles, the trophies and mementos of his pedestrian tours.
Now, he had not gone a hundred yards along this road when something caught his attention and he paused to examine it closely. It was nothing more than an arrow, possibly three inches long, chalked upon a rock at the roadside. As nearly as he could judge in the dusk, the color of the chalk was pink, but the arrow pointed neither up nor down the road, but across it toward the west. So he crossed the road, examining the bordering trees and land, but could find nothing. He sat down on a rock and thought. To the average boy a mark of this kind would have meant nothing. To a scout it might mean many things. But, unlike most of the scout signs, its meaning was not manifest. It was not the good road sign nor the bad road sign, nor was it the sign that a message was secreted near. Yet it pointed a direction; but the direction showed no path nor trail and was fast wrapping itself in darkness.
He rubbed his fingers over the arrow, making a powdery blur upon the rock and causing his fingers to feel smooth and powdery as he rubbed them together.
“This hasn’t been here long,” said he. Then he pondered, for he knew the rule that Dr. Brent was so fond of repeating. Use your brains first, then your hands and feet.
Gordon knew all the signs, Indian and otherwise, that scouts might employ, but he had never seen a scout mark made with chalk before, and it jarred upon his romantic sense to see this schoolroom material used for purposes of woodcraft. Yet there was the arrow, pointing directly across the road, apparently at nothing. He did not know what to make of it. Perhaps it was only a tramp’s mark. Perhaps—perhaps—then, suddenly, a thought came jumping into his head which gave him a thrill of joy. Three nights ago, in the club room, Dr. Brent had sketched Lake Champlain on the blackboard in pink chalk. That settled it. “I’ve found them,” he shouted, which was very much like him, for he was apt in his enthusiasms to anticipate his triumphs.
Leaping across the road, he got down on his hands and knees, lighting match after match, and searched the ground. Presently he noticed a log spanning the little marshy gully at the side of the road. This he had not seen before, for it was well hidden amid the weedy roadside growths. Now he saw that several reeds which had inclined across the path of this rough bridge had been broken, and hung limply over to one side. The log ran into a floor of pine needles, where no sign of footprint showed. But there were the arrow and the ford and the broken reeds, and these meant that somebody had crossed—crossed and flown up in the air, for all that he could discover. Nervous with expectation, he hurried about the grove, felt of the trees, knelt and examined rocks, and avoided kicking the smallest stone until he had observed its position in regard to other stones. Stealthily, silently, alertly, he moved about. His scout instinct was aroused. But he found nothing, and the long summer twilight was now almost at an end. Peeling some bark from a tree and pulling off a quantity of the sticky resiny substance from others, he hastily kindled a small fire. In a few moments this blazed up, showing him an illuminated area with a ground as smooth as a ballroom. There was not a sign of track or trail. He paused a moment, thinking. Then he pulled up his stocking, which was an indication that he meant business—a sort of challenge.
Thus, with all his spirit of adventure and scouting instinct, he stood, baffled but thoughtful, in the vast, strange country, with his eyes fixed on his little fire. For a moment he forgot Harry, forgot everything but the pink arrow, the log ford, and the broken reeds, and stood there, his brown eyes fixed on the dancing flame, his staff stuck in the ground beside him and his duffel bag thrown over it. Presently, he went back to the log, knelt down, and examined the end of it which rested on the bed of pine needles. On the near side of the log was a very slight oval depression in the ground in which the pine needles were rotted, and where a little red lizard lay contentedly in the dampness. On the side of the log nearest this depression several slugs crawled distractedly about. Gordon reached his arm across the log and rolled it back into the depression where it belonged. Then he sat down upon it and thought.
“Some one must have lost his balance in the middle of the log,” said he, aloud, “and in falling pushed it out of place.” And that could not have been long ago, for the slugs were still moving confusedly here and there and had not yet found the under side of the log. Gordon examined the muddy incline which led from the gully up into the grove. The dank, reedy foliage did not seem to have been disturbed, but in the brighter glow of his growing fire he presently noticed a well-defined, muddy imprint upon a flat rock. If he had discovered a diamond he could not have been more elated.
