“If I live that long,” corrected the young man; and stepped out briskly.

Jimmie knew that within a hundred yards a turn in the road would shut him from sight. So, he gave the stranger time to walk that distance, and, then, diving into the wood that lined the road, “stalked” him. From behind a tree he saw the stranger turn and look back, and seeing no one in the road behind him, also leave it and plunge into the woods.

He had not turned toward Bedford; he had turned to the left. Like a runner stealing bases, Jimmie slipped from tree to tree. Ahead of him he heard the stranger trampling upon dead twigs, moving rapidly as one who knew his way. At times through the branches Jimmie could see the broad shoulders of the stranger, and again could follow his progress only by the noise of the crackling twigs. When the noises ceased, Jimmie guessed the stranger had reached the wood road, grass-grown and moss-covered, that led to Middle Patent. So, he ran at right angles until he also reached it, and as now he was close to where it entered the main road, he approached warily. But, he was too late. There was a sound like the whir of a rising partridge, and ahead of him from where it had been hidden, a gray touring-car leaped into the highway. The stranger was at the wheel. Throwing behind it a cloud of dust, the car raced toward Greenwich. Jimmie had time to note only that it bore a Connecticut State license; that in the wheel-ruts the tires printed little V's, like arrow-heads.

For a week Jimmie saw nothing of the spy, but for many hot and dusty miles he stalked arrow-heads. They lured him north, they lured him south, they were stamped in soft asphalt, in mud, dust, and fresh-spread tarvia. Wherever Jimmie walked, arrow-heads ran before. In his sleep as in his copy-book, he saw endless chains of V's. But not once could he catch up with the wheels that printed them. A week later, just at sunset as he passed below Round Hill, he saw the stranger on top of it. On the skyline, in silhouette against the sinking sun, he was as conspicuous as a flagstaff. But to approach him was impossible. For acres Round Hill offered no other cover than stubble. It was as bald as a skull. Until the stranger chose to descend, Jimmie must wait. And the stranger was in no haste. The sun sank and from the west Jimmie saw him turn his face east toward the Sound. A storm was gathering, drops of rain began to splash and as the sky grew black the figure on the hilltop faded into the darkness. And then, at the very spot where Jimmie had last seen it, there suddenly flared two tiny flashes of fire. Jimmie leaped from cover. It was no longer to be endured. The spy was signalling. The time for caution had passed, now was the time to act. Jimmie raced to the top of the hill, and found it empty. He plunged down it, vaulted a stone wall, forced his way through a tangle of saplings, and held his breath to listen. Just beyond him, over a jumble of rocks, a hidden stream was tripping and tumbling. Joyfully, it laughed and gurgled. Jimmie turned hot. It sounded as though from the darkness the spy mocked him. Jimmie shook his fist at the enshrouding darkness. Above the tumult of the coming storm and the tossing tree-tops, he raised his voice.

“You wait!” he shouted. “I'll get you yet! Next time, I'll bring a gun.”

Next time, was the next morning. There had been a hawk hovering over the chicken yard, and Jimmie used that fact to explain his borrowing the family shotgun. He loaded it with buckshot, and, in the pocket of his shirt buttoned his license to “hunt, pursue and kill, to take with traps or other devices.”

He remembered that Judge Van Vorst had warned him, before he arrested more spies, to come to him for a warrant. But with an impatient shake of the head Jimmie tossed the recollection from him. After what he had seen he could not possibly be again mistaken. He did not need a warrant. What he had seen was his warrant—plus the shotgun.

As a “pathfinder” should, he planned to take up the trail where he had lost it, but, before he reached Round Hill, he found a warmer trail. Before him, stamped clearly in the road still damp from the rain of the night before, two lines of little arrow-heads pointed the way. They were so fresh that at each twist in the road, lest the car should be just beyond him, Jimmie slackened his steps. After half a mile the scent grew hot. The tracks were deeper, the arrow-heads more clearly cut, and Jimmie broke into a run. Then, the arrow-heads swung suddenly to the right, and in a clearing at the edge of a wood, were lost. But the tires had pressed deep into the grass, and just inside the wood, he found the car. It was empty. Jimmie was drawn two ways. Should he seek the spy on the nearest hilltop, or, until the owner returned, wait by the car. Between lying in ambush and action, Jimmie preferred action. But, he did not climb the hill nearest the car; he climbed the hill that overlooked that hill.

Flat on the ground, hidden in the golden-rod he lay motionless. Before him, for fifteen miles stretched hills and tiny valleys. Six miles away to his right rose the stone steeple, and the red roofs of Greenwich. Directly before him were no signs of habitation, only green forests, green fields, gray stone walls, and, where a road ran up-hill, a splash of white, that quivered in the heat. The storm of the night before had washed the air. Each leaf stood by itself. Nothing stirred; and in the glare of the August sun every detail of the landscape was as distinct as those in a colored photograph; and as still.

In his excitement the scout was trembling.
