“No use in rousing out the other men in a way to show the outlaws
you are expecting them.”
“Oh, shucks! are they watching us already?”
“They sure are. All I feared in making my way to your tent was their
sharp eyes. I knew what your guards would be.”
“You don’t have a very high opinion of us mule-skinners, then?” said
the captain, rather sharply.
“I have a very poor opinion indeed of men who will be careless on
this trail,” said Buffalo Bill sternly. “Recklessness is never bravery.”
“Huh!” grunted the other.
“Cook, you creep out at the rear and speak to the sentinel at the
back of the camp. Keep close to the ground and tell him to have a
care. Let him step across and speak to the guard by the river—
casually, remember.”
“All right, sir,” said the cook, recognizing the tone of authority.
“Then you creep over to the farther tent and awaken the boys
carefully. The captain here had better attend to the other two. Go on
your hands and knees, boys! And don’t startle anybody. Have they
got arms with ’em, or are they in the wagons?”
“Oh, they’ve got their rifles. I’m not quite a fool,” said the captain.
“Glad to hear that,” the scout returned, and did not stop to explain
whether he was rejoiced to hear that the men were properly armed,
or that the captain was not an entire ignoramus!
It was too serious a situation for the man to take open offense,
however. He, as well as the cook, did Cody’s bidding without further
remark. They crept from tent to tent, keeping well in the shadow,
while the first guard, warned by the cook, went across and warned
the man pacing the beat by the river.
Buffalo Bill was pretty confident that the outlaws would wait until the
sentinels were changed at midnight before attacking. That was the

best time for such a movement, for the new guards would be sleepy,
and the other men would have just settled into heavier sleep.
When the gang had been awakened the captain reported to the
scout. Thus far none of the boys had come out of the three larger
tents, and they were warned to keep under cover until they received
the word.
“You don’t want to have your mules stampeded far,” said the scout.
“When the sentinels are changed, let one of those coming off duty
step out and lead in your bell-mare, and hobble her inside the line of
the wagons. Then you’ll be sure of her, and, even if the long-ears do
run away, they’ll come back again, come daybreak.”
The cook’s fire was already out, and Cody warned them to let the
other one burn down as low as it would. The more shadowy the
camp was the better the freighters could move about without
attracting the notice of any watching outlaws.
Cody remained in the little tent with the flap pinned back, and the
cook and the captain came to him and reported their missions
accomplished. Midnight came—it was not a long wait—and the
sentinels went to the tents and appeared to awaken those who were
to relieve them. Cody had particularly instructed the man who was
to go to the river-bank. One of the others brought in the gray mare.
The camp settled down to apparent quietude and peace again.
“Now, boys, to your places,” whispered the scout to the cook and the
captain. “Signal your men, captain; be ready to fling on the fire a
heap of that light stuff yonder when you hear me hoot, cook! All
right!”
The captain crept out once more and scratched with his finger-nail
upon the canvas of each tent. At that the freighters began to wriggle
out from under the canvas and crawl on their bellies to shelter
beneath the wagons. Cody knew that the first fire of the outlaws
would be aimed at the tents. Boyd Bennett and his villains would
expect to thus kill or seriously wound several of the sleeping
freighters and throw the others into utter confusion.

Buffalo Bill remained no longer in the small tent himself. He crept
down to the river-bank, and he and the sentinel saw each other.
Cody expected a part of the attacking party would approach in the
way he had come to the camp, only from the other direction.
And this was a good guess. The outlaws—or several of them—
dismounted and came along under the bank. In fact, so sure were
they of catching the encampment asleep, that the scout heard their
footsteps. They did not take proper care in disguising them.
“Now, mister!” Buffalo Bill exclaimed, under his breath to the
sentinel near him.
Instantly this man dropped down in the grass, the other guard fell
flat, there was a sudden pounding of horse’ hoofs down the ridge
from the south and west. Then:
Bang! bang! bang!
A volley of rifle-shots tore through the tents inside the wagon-line.
Instantly the shrill yell of Buffalo Bill, the Border King, answered the
shots defiantly. The sound had often struck terror to the hearts of
his red foes, and it was not unknown to Boyd Bennett and his
comrades.
“That hell-cat, Cody, is here!” screamed Bennett.
The cook flung the light brush on the fire. It blazed up almost
immediately, giving the men under the wagons a chance to see any
of the outlaws that might venture into the camp. But none of them
reached the inner circle. As those afoot sprang up the bank from the
riverside, Cody and the man with him shot them down, or drove
them shrieking with fear out of rifle-shot.
Pandemonium reigned for a few minutes, however. Although Boyd
Bennett yelled his warning, the gang did not give over the fight so
easily. They poured round after round of bullets into the camp; but
at first they did not realize that they were being answered from
beneath the wagons rather than from the tents.

Several of their ponies were shot down. Although the mules were
stampeded for a ways, the ruffians could make no good use of this
fact. Instead of catching the camp unawares, they were themselves
ambushed, thanks to the Border King!
“Escape, men! We are undone!” shrieked Boyd Bennett, at last.
He had seen four of his men fall never to rise again, and two others
had lost their mounts and had to spend precious moments in
catching two of their dead comrades’ horses. Back the decimated
party fled over the ridge.
The freighters poured in volley after volley upon the retreating
outlaws. But the captain would not let them mount such horses and
mules as they could catch and follow the crew. In this he got square
with Buffalo Bill for the scout’s sharp words.
In the height of the fight, after seeing that the freight crew were
more than a match for the outlaws, Buffalo Bill had slipped down
under the river-bank and had run at his best pace toward the spot
where the outlaws had been encamped earlier in the evening. There
he had seen White Antelope tied to a sapling so that she could not
escape while her captors tried their nefarious scheme of robbing and
murdering the freight-train crew.
Believing that Bennett would leave nobody to guard the girl, the
scout was bent upon reaching the place first and releasing her.
And this much he did accomplish: he reached the place first. But
almost as soon as he had recognized Buffalo Bill’s yell, Boyd Bennett
spurred back toward the bound girl. He feared the scout would do
exactly the thing he was attempting. Knowing that Cody must have
followed them here for the express purpose of saving White
Antelope, he feared the shrewdness of his enemy.
Cody found the spot. A camp-fire burned low, but revealed the girl
writhing in her bonds at one side. The scout bounded to her side
just as the thunder of Bennett’s horse sounded down the hill.

“All right, White Antelope! ’Tis I—the Long Hair!” whispered the
scout. “My horse is not far away. I will save you—— The devil!”
The scout broke off with a savage exclamation. He had hoped to
slash through the girl’s bonds and carry her to his horse, which he
had left in a thicket not far away. But for once in his life the scout
had made a terrible oversight!
Chief had picked up a small pebble in his hoof late that afternoon,
and Buffalo Bill had got down and pried it out with the point of his
bowie. He had stuck the knife into a sheath which hung to his
saddle-bow, and had forgotten it until this very instant. He had
nothing with which to cut the girl’s bonds.
Already the chief of the bandits was almost upon him. Boyd Bennett
rode down the hill yelling like a fiend.
“Fly!” murmured the girl. “They will kill you.”
“Curse it! I am foiled for the time. But, remember, White Antelope, I
am near you and will release you yet, and serve your enemy as he
deserves!”
With these words the scout dropped to all fours, and, as stealthily
and silently as a wolf, crept away in the darkness.

The gang of outlaws had been depleted by five. One had fallen on
the river-bank, and four others had either been killed or so badly
wounded that they fell captive to the freighters on the side of the
ridge. There were but eight who gathered about the spot where
White Antelope was left tied, when the fight was over.
And they feared pursuit and a worse thrashing than they had already
endured. They clamored to be led away from the place, and Boyd
Bennett, gnashing his teeth in impotent rage, was forced to agree.
Every man of them had a fear of Buffalo Bill, the Border King. How
he could have gotten ahead of them, and been in the teamsters’
encampment when they made their attack, added to the
superstitious veneration in which the outlaws had begun to hold the
great scout. Heretofore they had held Boyd Bennett as a better man
than Cody; but now they began to doubt.
Besides, several of them did not approve of his bearing away the
Indian girl from her village. While Bennett had posed as the
medicine chief of the Sioux, they were all sure of being treated well
by the savages. Some of them had taken Indian wives and were
living in ease and plenty—the lazy, irresponsible existence of the
“squaw-man.”
Boyd Bennett’s unhappy attachment for the chief’s daughter had
brought the gang together again, and old-time loyalty had caused
them to answer his command. But they now believed that they had
lost more than they should gain. All the Sioux would be down upon
them, and so they would be at enmity with every man they met in
the forest and on the plain, both red and white!
White Antelope showed plainly that she would never yield to Boyd
Bennett’s demand and espouse him. While he was with the Indians

and wielding so much influence as Death Killer, the medicine-man,
she had spurned his advances. Much more did she hold him in
contempt now.
And Boyd Bennett, too, was acting very strangely. Evil ways and evil
desires were turning the man’s brain. He acted without judgment.
Now he unloosed White Antelope, caught her up to his saddle, and
rode away with his men without as much as looking for traces of
Buffalo Bill in the vicinity, or learning if in reality the freighters were
inclined to follow up their advantage and push the attack.
They swam the river and made for another exit from the valley. But
their horses were pretty well done up, and they could get only a
spurt of speed out of them now and then. Besides, Boyd Bennett’s
own mount refused after a time to carry double. This necessitated
one of the other ruffians carrying White Antelope before him on his
saddle.
The chance afforded the chief villain an escape from certain death.
The party were aiming to leave the valley by the way the broadening
river flowed; but they were some distance from the river’s side.
Through the uncertain light of early morning they did not see a
tireless white horse carrying its rider down the opposite bank until
they reached a ford, through which the stallion splashed to the side
of the stream on which the bandits rode.
It was the avenger on the villain’s trail; but they did not suspect that
again Buffalo Bill had ridden ahead of them. Chief was tireless.
The scout ensconced the horse behind a thicket, and wormed his
way out into the open where he could draw bead on anybody
passing along the river trail. It was a long shot, but the scout had
succeeded in making more ticklish ones in times past.
By and by the band of tired horsemen loped along the trail. The light
was too uncertain for Cody to distinguish one man from the other;
but he saw one riding ahead and carrying the girl before him, and he
believed it must be Bennett. He did not think the fellow would let the
White Antelope out of his own bloody hands.

Therefore he took sight—deadly sight—at this man, and shot him
through the head!
A yell rose from the bandits as the rifle exploded and the man
pitched off his mount. It was answered by Buffalo Bill’s eery war-
whoop. The seven remaining bandits knew who had fired the fatal
shot.
But, although the immediate captor of the girl had fallen, she had no
time to urge the pony to one side and thus escape. Buffalo Bill saw
his mistake in a moment. With a wild yell Boyd Bennett spurred to
the side of the horse which White Antelope sat, and threatened her
with drawn bowie as the whole cavalcade shot down the river trail
and put a brush-clump between them and the scout’s rifle. When
they appeared again they were out of rifle-shot.
“Seven of them left,” muttered Buffalo Bill. “I thought I had that
devil that time. But let him wait—let him wait!”
He mounted Chief once more and rode for a time in the wake of the
bandits. But, fearing that some of them might slip off their horses
and lay in wait for him, he turned aside into the hilly country and so
saw the refugees only occasionally from the summits of certain hills
which he climbed. He kept them from resting, however, during the
forenoon. By midday the desperadoes’ ponies were completely worn
out.
Had they not been so fearful of the scout the seven men might have
shown fight. They were equally well armed with Buffalo Bill, and
some of them were good shots. But Boyd Bennett thought only of
escape with the girl, and his mates were in a blue funk, anyway.
They came at noon to a deserted Indian encampment. It was a
hunting-camp, the braves evidently being out in the hills after game
and having left nobody but the squaws on guard. The squaws had
gone into the bush after late berries. Therefore, there was none to
balk the bandits.
There were no ponies, or the men would have left their fagged
mounts and stolen those of the red men. But in the river lay two

good-sized canoes. Abandoning their ponies the outlaws seized
these boats, forced White Antelope into the leading one with Boyd
Bennett and two others, and the four remaining men entering the
other boat, both were pushed off and paddled down the stream.
Cody beheld this move from a hilltop, and immediately rode down to
the river. Had he crossed the paths of any of the Indians—they were
not Sioux, but he knew the tribe—he might have obtained their help.
Alone, however, he came to the river-bank. The canoes were far out
in the stream and going down rapidly with the current and the force
of the paddles. The scout saw the White Antelope on her knees in
the forward boat, her arms stretched out to him. Her mute gesture
for help spurred him on to a desperate attempt!
Chief had come far now without much rest, but he was able to make
one more spurt. Down the river path the scout thundered, racing to
catch up with the canoes. There was a high bluff across the river,
offering no landing-place. On this side the bank was low. Even if the
canoes were paddled near the opposite shore, the scout’s rifle would
carry a deadly ball that distance. In coming near, and into sight,
however, he gave the bandits a chance to try their marksmanship
upon him.
But this risk the brave scout took. For the White Antelope’s sake he
was venturing his life.
He forced Chief to top speed until the brave old horse came out
upon a cleared space just ahead of the two canoes. The bandits
began to pop at him with their rifles; but shooting from a sitting
position in a trumpery little canoe was no easy job.
Both craft were overloaded, anyway. Two men were supposed to be
the full complement of the cargo of each. So the craft rode low, and
the least movement might tip them over. One man in the forward
boat, and two in the latter, turned their attention to the scout and
his white horse; but their bullets flew wide of the mark.
The scout, however, paid no more attention to the whistling lead
than he would have to so many buzzing flies. He dismounted from

Chief, and, standing out deliberately on the river-bank, raised his
rifle and took aim at the leading paddler in the rear boat. He did not
shoot at those with White Antelope in the other canoe. First he
would reduce the numbers of the gang.
Crack!
The heavy rifle spoke no louder than a pistol across the flat surface
of the water. With a yell the man dropped his paddle, turned a face
all gory upon the scout, and then pitched out of the canoe!
Strangely enough he did not tip over the vessel. Another caught up
his paddle. They tried to urge the craft to the foot of the steep bluff.
But now the current had caught the light canoe in a fierce grip, and
to swerve it was not easy.
Crack!
Just as a second man was drawing bead as well as he could upon
the undaunted scout, the rifle dropped from his hands, and he fell
backward into the bottom of the canoe. The craft dipped
dangerously and all but went over. As it righted the scout fired a
third time. Plunk the ball went through and through the body of the
canoe!
The water began to run in at both holes, and the canoe sank. One of
the remaining men, in complete panic, threw himself overboard and
swam for the shore. The other continued to paddle desperately.
A double report sounded. The rifleman in the forward boat had
stood up and taken a better aim at the scout. The latter’s shoulder
was plowed just under the skin by the ball. But Cody’s own bullet
sped straight to the desperate paddler in the second canoe, and the
man fell sideways, shot through the lungs; the canoe tipped
completely, and man and canoe went to the bottom together.
Meanwhile, the fourth man in that boat had reached the strand. It
was a narrow beach and offered no shelter for him. He scrambled up
the steep bluff like a crab making for its hole. But when he was half-

way up, and his body against the yellow sand made an excellent
target, the scout’s gun spoke again.
Sprawled out, and screaming, the fellow fell all the way back to the
shore, and there, squirming with the agony of the wound which was
in a vital part, he rolled into the river, and the black current swept
him swiftly down-stream.
He passed the first canoe that had been retarding, while the
rifleman tried a second particular shot at the scout. The drowning
man yelled for help. He even snatched at the gunwale of the canoe
as he was swept by.
Instantly Boyd Bennett seized a pistol from his belt and deliberately
shot the drowning man through the head. Perhaps, if the latter had
seized the canoe, he would have overturned it and sacrificed the
four other lives; yet it was a desperately cruel act!
Meanwhile Cody had leaped aside, escaping the second shot of the
rifleman in the remaining canoe; and then, before the man could sit
down and the canoe could shoot ahead, he dropped him cleanly with
a ball through the heart!
In five minutes the bloody battle was over. But two of the bandits
were left alive. The other five had sunk to the bottom of the river,
while the remaining two, and the White Antelope, were being carried
swiftly down the stream, and by a current now so powerful that they
could not steer to the bank on either side. Just below were the worst
series of rapids on the entire river!

CHAPTER XLIII.
MAN TO MAN AT LAST.
Buffalo Bill knew the peril which threatened the two bandits and the
girl quite as soon as they knew it themselves. But he was
handicapped a bit now by his wound, which bled profusely. He had
to wait to bind it up roughly, so that the blood would stop flowing,
before he could pay much attention to the endangered trio in the
canoe.
Ere then the craft was swiftly speeding down the river, going almost
as fast as an ordinary horse could trot. Buffalo Bill whistled Chief to
him, sprang into the saddle, and galloped down the trail. It was
some minutes before he overtook the boat.
There was no danger then of anybody aboard it shooting at him.
Boyd Bennett in the stern and his last comrade in the bow were
having all they could handle in steering the craft. Rocks and snags
began to crop up in the current, and they were now tossed this way,
then that, while the foaming water boiled almost into the frail craft!
Buffalo Bill, intent on saving White Antelope’s life at any cost,
unslung his lariat and made ready to cast the endangered men an
end if the canoe came near enough to the shore. For the sake of
assisting the girl he would have given up his vengeance on the
outlaws.
However, when he cast the rope, although it fell across the boat,
Boyd Bennett, with a scream of rage, threw it off.
“You madman!” yelled his companion, glancing over his shoulder.
“Mind your paddle!” roared Bennett.
“My God! I’ll take help from anybody,” cried the other.

Cody coiled his rope to swing it again, this time intending to aim
ahead of the canoe so that the other man could catch it. But Bennett
saw his intention, and he drew in his paddle, grabbed his pistol, and
presented it at his comrade’s back. White Antelope was lying down
in the canoe, knowing that this was the safest place for her.
“You touch that rope!” shrieked the bandit leader, as the lariat
whistled through the air again, “and I’ll send you to Hades!”
The man glanced fearfully over his shoulder at the words, and saw
the threatening pistol.
“Look out!” shouted Buffalo Bill, for his cast had been true, and the
coil of the lasso was circling just over the man.
The fellow was too scared of the pistol to watch the loop, and it
settled fairly over his head. With a shriek he tried then to get out of
it, but it was too late. The canoe darted suddenly into a cross
current, shooting off from the shore, and the rope was pulled taut.
Buffalo Bill could not have released the rope from his saddle-bow in
time to save the unfortunate outlaw, nor could he force Chief nearer
the water. The noose was about the man’s neck, and with an awful
jerk the rope literally snatched him out of the canoe!
Had the girl not been lying down at the moment his body would
have carried her likewise into the river. It was by mere chance that
the canoe did not overturn; but it righted and sailed on with its
freight of two. The other outlaw was dead before Buffalo Bill could
drag him ashore. His neck had been broken.
The scout’s interest lay, however, in the fate of the two remaining in
the canoe. He cast the dead man loose and spurred hard down the
path, trying to keep up with the frail canoe now shooting the rapids.
It was a perilous journey; yet Boyd Bennett, ruffian though he was,
exercised the greatest ingenuity in managing the canoe. The scout
could not but admire this in the fellow.
It seemed impossible, however, that the canoe and its living freight
could get through the rapids intact. The water boiled madly about

the craft. It was flung hither and yon, and at times it was so racked
by the opposing forces of the current that Buffalo Bill, on the bank,
could hear the wood crack.
Boyd Bennett’s glaring eyes did not turn toward his enemy
throughout all this trial. He watched each black-ribbed rock or
floating snag against which his craft might be hurled. Nor did he
speak a word to the girl lying in the bottom of the canoe.
She knew as well as he that any movement on her part would add to
their danger, and, although she might now leap overboard—she was
free—it would mean certain death. So freedom tantalized her. She
could only escape at the peril of her life!
She saw Boyd Bennett’s glowing eyes occasionally cast upon her a
basilisklike glance. There was madness in them, she knew. The
brave girl, used as she was to battle and the chase, shrank from this
terrible foe. And she was helpless!
The canoe swung around rocks, which she thought surely they must
hit; it just escaped collision with logs and drift-stuff in the most
marvelous manner, and all the time Boyd Bennett sat holding the
paddle as a steering-oar, his black eyes glaring out of his death’s-
head face, impassive, yet all alive to the dangers of the run.
Spray broke over the side of the canoe and drenched the girl. The
craft seemed to fairly throb and jump with the motion of the water.
Once an eddy seized them. Despite all Bennett could do the canoe
shot into this whirlpool, and they made several rapid revolutions
before the man saw his way out, and thrust the canoe between two
ragged jaws of rock, and so escaped!
On and on fled the boat, while Buffalo Bill urged his mount along the
river path. He could barely keep up with it. Each moment he
expected to see it overturned, and both passengers tumbled into the
raging current.
At last the more quiet river below the rapids came into view. Here
the stream widened and the current quickly became sluggish. In the

midst of the stream was a wooded island, its sharp upper end,
consisting of an outcropping ledge, dividing the river into two
channels just at the foot of the white water.
The canoe, as it shot out of the smother of spray, chanced to take
the channel nearest to the bank on which Cody urged his horse. This
was an oversight on Bennett’s part, but he had been too anxious to
get out of the rapids at all to attend to where the canoe finally went.
Cody saw his chance, and, although Chief was well winded now, he
yelled with delight. He saw what appeared to be the finish of the
race—and in his favor.
“I’ve got you now, Boyd Bennett!” he shouted.
The bandit at last turned his eyes upon him, and then glanced
around. He saw Cody’s meaning. The canoe was drifting so near the
scout that the latter could either shoot, or rope him. And the long
island forbade his getting away.
But the villain was not yet to his last card. His mind was keenly alive
to the situation, and he lost no points in the game.
“Not yet, Bill Cody—not yet!” he shrieked, and with a single thrust of
his paddle, turned the canoe’s nose toward the island.
“Hold, or I fire!” cried the scout, raising his weapon and drawing
bead upon the bandit.
Boyd Bennett drove the canoe into the rocky ledge which masked
the end of the island. Like paper the frail craft tore apart, and both
he and the girl were flung into the stream.
Buffalo Bill’s bullet flew wide of its mark that time! White Antelope
was in as much danger as the bandit—perhaps more—for the scout
did not know whether the girl could swim or not, and the current
was still quite swift and the water deep.
But White Antelope soon showed what she could do in the river. Cold
as the water was, the instant she came to the surface and saw Boyd
Bennett’s arms stretched out for her, she threw herself backward

and dove again to the bottom of the river! With a yell the bandit
flung himself after her, and again just missed the scout’s bullet. The
scoundrel seemed to bear a charmed life. Buffalo Bill was unable to
hit him. Although they were man to man at last, it was a question
still who would come out winner in the game.

CHAPTER XLIV.
THE FIGHT TO GAIN THE ISLAND.
White Antelope sank to the bottom of the river; then, unlike ordinary
swimmers, she did not move in a straight line, but shot off at a
sharp angle, and endeavored to make the shore where Cody was,
while still under water. But Boyd Bennett was quite as cunning. He
cut across her path, and, as the girl came shooting in a long slant to
the surface of the river, he reached and caught her by the shoulder.
White Antelope screamed and sought to wrench herself away. Cody
had flung aside his rifle and urged Chief down into the stream. The
white horse was already belly deep in the flood, picking his way
intelligently, while his master, rope in hand, prepared to fling the
loop to the Indian maiden.
But before Cody could make the cast, Bennett had grabbed the girl
and thrust her under the surface again. White Antelope went down
gurgling, and the cruel hand of the bandit chief held her fast. With
an oath the scout seized a revolver and aimed at the black, sleek
head of the scoundrel.
“Hold your fire, Bill Cody!” cried the bandit again. “Hold your fire, or
I’ll drown this girl—as sure as you live, I will! She’s mine, and, by
Heaven, you sha’n’t take her from me—unless it’s her dead body!”
“You devil, you!” roared the scout. “You are drowning her!”
“I surely will if you don’t put up your gun!”
“Let her up!”
“Put away your gun!”
The scout was obliged to do so. If he shot the scoundrel the latter
might sink, his clutch still upon the White Antelope, and neither of
them rise again until the breath had left both their bodies!

Boyd Bennett saw the scout put the gun back into his belt. He then
dragged the girl up by her long, golden hair, and with her in his arms
—she was now totally unconscious—he struck out with his free hand
for the island. The scout seemed helpless. There was nothing he
could do to stop the foe or free the girl. The situation stumped
Buffalo Bill completely!
All the scout could do was to wait, hand on gun, for some chance to
aid his cause. While Bennett struggled in the river with the girl he
dared not fire for two reasons. One, already stated, was that he
feared the man would sink with his burden and both be drowned;
the other was that he feared his pistol-ball might wound the girl as
well as Bennett.
And now it was not altogether sure that the scoundrel could make
the shore of the island. He was weaker than he had been, and the
burden of the girl bore him down. There was a current set off from
the island on this side, and he had this to fight. And fight he did—
with a bravery which Cody could but admire. He breasted the
current, and fought inch by inch the downward drag of the river. It
was too much for him, however.
Suddenly the bandit almost lost his hold upon the girl. Cody believed
he was about to give her up and save himself, and he prepared to
force Chief into the deeper current and so swim out for her. He
swung his lariat again, too, that it might be ready for emergency.
But, although Bennett was carried down-stream and the shore of the
island was rapidly receding from him, he still clung to the Indian
maid.
“Look out for the rope, Boyd Bennett! Catch it!” sang out the scout,
believing that now the fellow would certainly rather save his life and
lose the girl than lose both his own and her lives. But a sputtering
shriek came back from the maniac:
“Fling your rope if you dare, Bill Cody! I’ll kill her if you do—mark
that!”
“Don’t be a fool, man. You can’t save her and yourself.”

“Then we’ll both drown,” returned Boyd Bennett, with the
determination of a still fearless man.
“I’ll give you your freedom!” roared Cody, at desperate straits now.
“I’ll not take it of you. If I die she goes with me—ah!”
A sudden eddy seized the man and swung him toward the island. He
had evidently stored some remaining energy, and this he now put
forth. He seemed fairly to leap forward in the water which was over
his head near the bank. But he caught at a drooping tree-branch
and held on.
Now, could Cody only have reached him, Boyd Bennett would have
been at his mercy. But only for an instant did the weakness
overpower him. He swung in shoreward, his feet found footing on a
ledge of rock, and in another minute he clambered up out of the
water, and, with the unfortunate girl still hanging limply over his
shoulder, passed out of the scout’s sight!
The island was well wooded. It contained about half an acre and
was long and narrow. It was so long that from the bank to which
Cody had again turned his mount, he could not see whether the
bandit found some immediate way of leaving it, and so reaching the
farther shore of the river, or not.
There was no time to waste for Buffalo Bill, therefore. He must press
after the man and the girl, giving the former no time to recover his
strength, and, perhaps, make his escape from the island.
But Chief could not help his master across the deep water to the
ledgy island. Nor could Buffalo Bill make it encumbered by his heavy
accouterments. That was not to be considered for a moment!
He dismounted and let Chief go free. The old horse had done his
share well, and as soon as he was relieved of the saddle and bridle,
he lay down and rolled as though to get the cramps out of his body.
The water of the river was ice-cold.
It even made Cody shrink when he contemplated it. His only way of
reaching the island was by swimming, and against that current, and

with the chill evening coming on, the scout might well hesitate. But
not for long. What must be done would better be done quickly, and
the Border King was well inured to exposure and cold. He threw
aside his ammunition-belt and his weapons. His coat, waistcoat, and
outer shirt went likewise. Off came his riding-boots, and then in his
undergarment, and with his bowie between his teeth, he plunged
into the flood and essayed the venture.
Whether he was being watched from the island by his enemy, Cody
did not know. But this was the only way he saw to get at Boyd
Bennett and the girl. He was matching his life against the bandit’s
now, in the last desperate act of the series which had followed the
abduction of White Antelope early the day before.
