<h4>CONCLUSION</h4>
<p>The enemy answered the shots with a volley, and for a few
moments a lot of ammunition was wasted while the odor of
gunpowder assailed nostrils on both sides.</p>
<p>After that, the shooting died away. As the minutes lengthened
into an hour, and no word of Tad's mission had been received, the
defenders began to grow restless. They were under a double
tension now. Mr. Marquand was pacing up and down the floor.</p>
<p>Suddenly, forgetful of the danger that lurked out there, he
poked his head out of the window.</p>
<p>A sharp <i>pat</i> on the stone window frame beside him, after
the bullet had snipped off the tip of his left ear, caused Mr.
Marquand to draw back suddenly. He stalked about the floor,
holding a handkerchief to the wounded ear, "talking in dashes and
asterisks," as Chunky put it.</p>
<p>Kris Kringle's face wore a grim smile. He was taking chances
of being shot, every second now, but he insisted in holding his
place at the side of the window so he could listen and watch.</p>
<p>A thin, fleecy veil covered the moon, but it was not dense
enough to fully hide objects on the landscape.</p>
<p>"All keep quiet, now," warned Kris Kringle. "We should get a
signal pretty soon."</p>
<p>"I'm afraid something has happened to the boy," muttered the
Professor. Then all fell silent.</p>
<p>"There it goes!" exclaimed the guide in a tone of great
relief.</p>
<p>The crack of a rifle afar off sounded clear and distinct.</p>
<p>"He's made it. Thank heaven!" breathed Mr. Marquand
fervently.</p>
<p>Chunky leaped to the opening, swung his sombrero as he leaned
out, and uttered a long, shrill "y-e-o-w!"</p>
<p>A bullet chipped the adobe at his side. Stacy ducked, throwing
himself on the floor, sucking a thumb energetically.</p>
<p>"Wing you?" inquired Kris Kringle.</p>
<p>"Somebody burned my thumb," wailed the fat boy.</p>
<p>"It was a bullet that burned you. Served you right too.
Somebody tie that boy up or he'll be killed," counseled the
guide.</p>
<p>The besiegers could not have failed to hear the shot from
Tad's rifle, but it did not seem to disturb them. They evidently
did not even dream that one of the party had escaped their
vigilance and that he was well on his way for assistance.</p>
<p>The wait from that time on was a tedious and trying one,
though each felt a certain sense of elation that Tad Butler had
succeeded in outwitting the enemy.</p>
<p>It was shortly after two o'clock in the morning when Kris
Kringle espied a party of horsemen slowly encircling the adobe
house. The riders were strung out far off on the plain. Those
hiding in the sage in front of the house could not see the
approaching horsemen.</p>
<p>"There they come," whispered Kris Kringle. "Begin
shooting!"</p>
<p>The two men started firing, while the besiegers poured volley
after volley through the window.</p>
<p>The posse at this, closed in at a gallop. Their rifles now
began to crash.</p>
<p>In a few minutes it was all over. The sheriff's men surrounded
the besiegers, placing every man of them under arrest. After this
the officers quickly liberated the Pony Rider Boys. Three of the
besiegers had been wounded. Among them, was the Mexican whom Tad
had defeated in the tilting game a few days before.</p>
<p>When all was over, the boys hoisted Tad Butler on their
shoulders and marched around the adobe house shouting and
singing. Mr. Marquand decided to go back with the posse, using
these men as a guard for his treasure. It was understood that the
Pony Rider Boys were to follow the next morning. Before leaving,
Mr. Marquand called the Professor aside.</p>
<p>"There is, on a rough estimate, all of sixty thousand dollars
in the treasure chest. Had it not been for you and your brave
boys I should have lost it. So, when you reach Hondo to-morrow, I
shall take great pleasure in presenting to each of you a draft
for two thousand dollars."</p>
<p>Professor Zepplin protested, but Mr. Marquand insisted, and he
kept his word. After the posse, with their prisoners and the
treasure, had started, the Pony Rider Boys, arm in arm, started
off across the moonlit meadows toward their camp. It was their
last night in camp. Their summer's journeyings had come to an
end—a fitting close to their adventurous travels. Not a
word did they speak until they reached the camp. There, they
turned and gazed off over the plain which was all silvered under
the now clear light of the moon.</p>
<p>"It has been a silver trail," mused Tad Butler.</p>
<p>"It has indeed," breathed his companions</p>
<p>"And we've reached the end of The Silver Trail," added the
Professor, coming up at that moment. "To-morrow I'll breathe the
first free breath that I've drawn in three months."</p>
<p>The boys circled slowly around him and joined hands. Then
their voices rose on the mellow desert air to the tune of</p>
<p align="Center" class="center">"Home, Sweet Home."</p>
<p>A week later saw the wanderers back in Chillicothe. Their
welcome was a warm one. Banker Perkins found his once ailing son
now transformed into a sturdy young giant.</p>
<p>We shall meet them again in the next volume of this
series—in a tale of surpassing wonders—published
under the title: "THE PONY RIDER BOYS IN THE GRAND CANYON; Or,
the Mystery of Bright Angel Gulch." It will be found to be by far
the most interesting volume so far published about the splendid
Pony Rider Boys.</p>
