# The Tower Treasure/Chapter 6

CHAPTER VI
Tire Tracks
Next day was Saturday, and immediately after breakfast the Hardy boys asked their mother to make up a lunch for them, as they intended to spend the day in the woods with a number of their school chums.
Mrs. Hardy quickly made up a generous package of sandwiches, not forgetting to slip in several big slices of the boys' favorite cake, and the lads started out in the bright morning sunshine, with the whole holiday before them.
They met the other boys, half a dozen in all, on the road at the outskirts of the town and so, whistling and chattering and telling jokes, the group trudged along the dusty highway. Once in a while they would explore along the fences for berry bushes, and occasionally a friendly scuffle would start, to end with both laughing contestants covered with dust.
When they reached the crossroads Chet had not yet appeared, so they rested in the shade of the trees until at length the chubby youth ​came panting along the road, his lunch under his arm.
"If I only had my roadster I wouldn't be late," he said, as he came up to them. "I've been so used to it that I've forgotten how long it takes to walk this far."
"Well, are we all set?" asked Frank.
"Everybody's here. Where are we going?"
"What do you say to Willow Grove?"
"All those in favor say 'Aye'," demanded Chet, and there was a chorus of "Aye" from the crowd.
"It's unanimous," Chet decided. "Willow Grove it shall be. Let's go."
Willow Grove was about a mile farther on. It was some distance in from the road, and was on the banks of Willow River, from which it got its name. It was an ideal place for a picnic, and as it was somewhat early in the season it was hardly likely that other parties from the city would be in the grove that day.
Frank told the other boys about Chet's adventure with the auto horn and the story was greeted with shouts of laughter, which were redoubled when Chet told how he had later jumped down from the wagon and run along a shouting to Lem Billers to give him a ride.
"It was a shame!" he confessed. "The poor old chap reined in his horses and made me ​come up and sit on the seat beside him. He asked me if I had walked very far and then he told me all about his argument with the policeman and the chauffeur. I could hardly keep my face straight."
When the boys reached the lane that led in toward Willow Grove from the main road they broke into a run and raced into the woods, shouting and yelling like wild Indians. Once in the friendly shade of the trees they capered about in the joy of their Saturday freedom. Chet took charge of the lunches and stored them in a convenient clearing, and then began the rush for the river.
The day passed in the usual fashion of such days. They swam, they ate, they loafed about under the trees, they played games at imminent risk of life and limb, they explored the woods, and otherwise enjoyed themselves with all the happy energy of healthy lads. Joe Hardy, who was an amateur naturalist in his way, went roaming off by himself during the afternoon while the other boys were enjoying their third swim of the day, and penetrated deeper into the woods.
He poked about in the undergrowth, examining various flowers and plants that came to his attention, but discovered no specimens that he had not seen before. He was just on the point of going back to the other lads when he saw be​fore him a small clearing. It was a part of the grove in which he had never been, so he ploughed on through the bushes until he found himself in a clearing that appeared to be part of an abandoned roadway.
It was in a low-lying part of the grove and the ground was wet. At one point it was muddy, and in this mud Joe saw something that aroused his curiosity.
"Tire tracks, eh! There's been an automobile in here," he muttered to himself. "I wonder how on earth a car could get this far into the woods!"
Then he remembered his father's remarks on the value of developing his powers of observation, so he went over closer and examined the marks in the mud.
"That's a strange tread," he thought. "I've never seen a tire mark quite like that before."
He gazed at it until he was sure that if he ever saw a similar auto tread again he would recognize it.
"That just goes to prove that dad was right," said Joe. "Probably I've seen auto tires like that often, but I've never noticed the markings, and now that I do notice one in particular it seems strange to me. But I wonder what an automobile was doing in here and how it came to get here in the first place!"
However, he gave the matter little further ​thought and retraced his steps through the woods until he returned to the other boys, who were getting dressed after their swim.
"I thought automobiles weren't allowed in Willow Grove," he said casually to Chet Morton.
"Neither they are. You have to park just inside the fence."
"Well, somebody brought a car right down into the grove."
"They couldn't. There's no road."
"Well, there's a sort of clearing over there," said Joe, motioning in the direction from which he had just returned. "It looks as if it had been a road at one time."
"That's probably the old creek road. It hasn't been used for years."
"Well, it was used just this week. I saw the marks of an automobile tire over there not ten minutes ago. And it was a mighty peculiar tread, too. Like this—," and Joe commenced to draw a replica of the design in the sand, using a thin stick of wood as a pencil.
Chet Morton stared.
"Why," he exclaimed, "there's only one car in the city has tires like that!"
"Whose car?"
"Mine!" exclaimed Chet, springing to his feet. "Where is this road you found?"
Joe Hardy quickly led the way and all the ​other boys came trooping along behind, the whole band thrown into a state of great excitement by this unexpected discovery. They all knew that Chet's car was of an unusual make and that the tires were distinctive. When they reached the clearing and Chet had examined the imprint in the mud he exclaimed:
"There's no mistake about it! My car has been here! No other car in the city has a tread like that!"
"Perhaps the car is still around here," suggested Frank quickly. "For all we can tell, the thief may have abandoned it and picked this road as a good place to hide it."
"It would be an ideal place," agreed Chet. "This road leads off the main highway, and it isn't often used. Let's take a look around, anyway."
The boys quickly scattered, some taking one side of the road, the rest taking the other. For a while the search continued without success, but at last Frank and Chet, who were following the abandoned road farther down, gave a simultaneous cry.
"Here's a bypath!"
Before them was a narrow roadway, overgrown with weeds and low bushes that almost hid it from view. It led from the abandoned road into the very depths of the wood. Without hesitation the two boys plunged into it.
​The narrow roadway widened out farther on, then wound about a heavy clump of trees, until it came to an end in a wide clearing.
And in the clearing stood Chet Morton's lost roadster!
"My car!" yelled Chet, in delight.
His shout was heard by all the other boys, and the sound of snapping twigs and crackling branches soon told Frank and Chet that the others were losing no time in reaching the scene.
Chet's delight was boundless. He examined the car with minute care, in every particular, while the other boys crowded about. At last he straightened up with a smile of satisfaction.
"She hasn't been damaged a bit. All ready to run. The thief just hid the old bus in here and made a getaway. Come on, fellows, we don't walk back home to-day. We ride."
He clamored into the car and in a few seconds the engine roared. There was sufficient room in the clearing to permit him to turn the roadster about, and when he swung the car around and headed up the bypath the boys gave a cheer and hastened to clamber on board.
Lurching and swaying, the roadster reached the abandoned road and from there it was an easy run to the main highway. In spite of the fact that it had been left in the bush for probably a week, the roadster was in perfect con​dition and the engine ran smoothly. Joe was given the seat of honor beside the driver, because he had discovered the tire marks that had led to the recovery of the car, and the other boys distributed themselves as best they could. They clung to the running boards, hung precariously to the back, and one lad even straddled the hood. In this manner the triumphal procession returned to Bayport.
But as the cheering lads came down the main street they noticed that there was an unwonted air of excitement in the town. People were standing on the street corners in little groups, talking earnestly, and when the boys spied Detective Smuff, of the police force, striding along with a portentous frown, they called out to him.
"What's on your mind to-day, detective? Chet got his car back!"
"I've got something more important than stolen cars to worry about," declared Detective Smuff. "The Tower Mansion has been robbed."
