"Loose bowlder! Look out fer it, boy!"
The others were yet some distance away, so that Frank and Gabe were together, the boy being astride his heavily breathing horse.
With each moment the roaring grew louder, till it swelled to jarring thunder, and then past them shot a huge black ma.s.s, enveloped in a cloud of dust. This ma.s.s leaped down into the black depths of a great chasm that yawned close at hand.
Frank"s horse was frightened and began to plunge. The boy tried to quiet the animal, which was no easy task. In its mad plunging the creature reached the edge of the chasm. Big Gabe leaped forward with a second shout of warning, but it came too late.
Horse and rider went over the brink!
CHAPTER XLIII.
A FRIGHTFUL PERIL.
Not a sound came from the lips of our hero as his horse went plunging into the chasm, although, in the moment when he went over the brink, the boy fully expected to be dashed to death in the dark depths below.
He saw Big Gabe leap to clutch him, but realized that the giant was too late.
In that fateful moment Frank cleared his feet from the stirrups and made a desperate effort to save himself.
Too late!
All he could do was to clutch at the high pommel of the Mexican saddle, to which he clung tenaciously.
A wild, half human scream of terror came from the throat of the horse.
"Whoa up, thar!" roared the giant, as he made a clutch at the horse.
By rare good fortune the man clutched the flowing tail of the animal fairly and firmly. His heels settled into a rift of the rocks, and he surged backward.
Over went the horse, dangling, head downward, above the terrible chasm, while the giant held it thus by clinging to the creature"s tail!
And our hero held fast to the Mexican saddle!
Frank was amazed when he found the horse was not going downward, and, being unable to see the big man, he wondered what held the animal suspended in the air.
In a moment the man above cried:
"Are you gone, boy? Are yer done fer, youngster?"
"No," replied Frank, with sudden hope. "I am hanging to the saddle.
Drop a rope to me, and pull me up--quick, before the horse falls!"
"Can"t do it."
"Why not?"
"I"m holdin" ther critter by ther tail, an", burn me, ef yer both won"t go to ther bottom ef I leggo!"
Then the boy realized what had saved him, impossible as it seemed, and he marveled at the astonishing strength of the strange giant who had been sent to Lake Tahoe to die of consumption.
"But he can"t hold out long!" thought the lad. "He must give up in a moment, and then we"ll go down to death!"
It was not a pleasant thought, and still Frank was not terrified. He wondered at his own coolness. He speculated on the length of time they would be falling. Would he be conscious when they struck, or would the fall rob him of his senses?
He looked down. Far below, ragged points of rocks jutted out from the chasm wall, seeming to beckon to him. They would bruise and tear him, and it seemed that they were awaiting, with impatience, for him to fall.
He could not see the bottom of the chasm!
"It is sure death!"
Without knowing that he did so, he uttered the words aloud.
"Not ef I kin hold on a little longer, boy."
The giant had heard him and made reply, much to his surprise, for he had seemed to forget that Blake was holding him from falling.
Then he marveled more than ever at the strength of the man, for it began to seem that he had been suspended thus many hours. Surely Gabriel Blake possessed supernatural prowess.
Something like a laugh came from the boy"s lips.
"It is foolish to try to hold on longer," he said, a bit wildly. "Let go, before you, too, are dragged over to death."
"Hyar, hyar!" called the man from above. "Don"t git nutty, boy! I kin hold yer some time yit."
Still Frank was sure it was all folly; it could only end in one way.
"I must fall at last!"
The giant heard these hoa.r.s.ely muttered words, and he feared the boy would let go.
And now Bart Hodge and the two men had become aware of Frank"s peril, and they were spurring their horses madly forward, having reached the top of the climb.
The giant saw them coming, and it gave him new strength.
"Hold fast, down thar, youngster!" Big Gabe shouted to Frank. "Thar"s help comin" hot-foot an" hustlin". We"ll hev yer out uv thar in two shakes, brand me deep ef we don"t!"
Still, Frank did not dare to hope. Once or twice it seemed that the horse, wild-eyed and snorting with terror, slipped a bit, and the boy fancied Gabe was losing his grip.
It was a fearful strain on the giant, but he held fast as if his own life depended on it. The cords stood out on his neck and forehead, and perspiration rolled down his face. He could hear his own heart thumping like a hammer in his breast.
The sheriff, Sile Jones and Bart Hodge came tearing up to the spot, flung their horses back with a surge at the bit, and leaped to the ground.
In a moment Jones had leaped to the side of Big Gabe and obtained a hold on the tail of the horse, relieving the giant a bit.
