Craig looked around hastily. In a corner, just back of us was a long pole. He s.n.a.t.c.hed it up and moved cautiously toward the window, keeping the pole as level as possible as he endeavored to get a leverage on the sash. The flames were mounting faster and higher, licking up everything.

"Keep back, Walter," he muttered, "just as far as you can."

He had scarcely raised the window a fraction of an inch when an old rusty, heavy anvil and a bent worn plowshare crashed down to the floor directly over the spot where I should have been if he had not dragged me away. I started back, aghast. Nothing had been overlooked to finish us off.

"I think you may try it safely now, all right," smiled Kennedy coolly.

We climbed out of the window, not an instant too soon from the raging inferno about us.

Having gained the clump of woods, the gaunt figure had paused long enough to gloat over his clever scheme. Instead, he saw us making good our escape. With a gesture of intense fury he turned. There was nothing more for him to do but to zigzag his way to safety across country.

The barn was now burning fiercely and it was almost as light as day about us. Kennedy paused only long enough to look down at the ground where the fire had been started.

"See, Walter," he exclaimed pointing to a square indention in the soft soil. "No white man ever made a footprint like that."

I bent over. The prints had the squareness of those paper-layered soles of a Chinaman.

"Long Sin," came the name involuntarily to my lips, for I knew that Wu would delegate just such a job to his faithful slave.

Kennedy did not pause an instant longer, but in the light of the burning barn, as best he could, started to follow the trail in a desperate endeavor either to overtake Long Sin, or at least to find the final direction in which he would go.

At the entrance of the pa.s.sageway which led to the little underground chamber in which we had sought the treasure hidden by the Clutching Hand, Wu Fang was seated on a rock waiting impatiently, though now and then indulging in a sinister smile at the subtle trick by which he had recovered the ring.

The sound of approaching footsteps disturbed him. He was far too clever to leave anything to chance and, like a serpent, he wriggled behind another rock and waited. It was only a glance, however, that he needed to allay his suspicions. It was Long Sin, breathless.

Wu stepped out beside him so quietly that even the acute Long Sin did not hear. "Well?" he said in a guttural tone.

Long Sin drew back in fear. "I have failed, oh master," he replied in an imploring tone. "Even now they follow my tracks."

It was bad enough to confess defeat without the fear of capture.

Wu frowned. "We must work quickly, then," he muttered.

He picked up a dark lantern near-by, indicating another to Long Sin.

They entered the cave, flashing the lights ahead of them.

"Be careful," ordered Wu, proceeding gingerly from one stepping-stone to another. "We shall be followed no further than this."

He paused a moment and pointed his finger at the earth. Everywhere, except here and there where a stone projected, was a sticky, slimy substance. It was an old trick of primitive races.

"Bird lime," hissed Wu, pointing at the viscid substance made of the juice of the holly bark, extracted by boiling, and mixed with a third part of nut oil and grease.

They pa.s.sed on from stone to stone until they came to the subterranean chamber itself. Without a moment's hesitation, Wu made his way toward the rock in which they had found the slot with its cryptic inscription.

Long Sin watched his master in silent admiration as, at last, he drew forth the mystic ring for which they had dared all.

Without a word, Wu dropped it in the slot. It tinkled down the runway, a protuberance hit a trigger and pushed it a hair's breadth.

A noise behind them caused the two to turn startled. Even Wu had not expected it.

On the other side of the chamber, a great rock in the ground slowly turned, as though on a pivot. They watched, fascinated. Even then Wu did not forget the precious ring, but as the rock turned, reached down quickly and recovered it from the cup at the floor.

Inch by inch the pivoted rock moved on its axis. They flashed their lanterns full on it and, as it moved, they could see disclosed huge piles of gold and silver in coins and bars and ornaments, a chest literally filled with brilliants, set and unset, rubies, emeralds, precious stones of every conceivable variety, a cave that would have staggered even Aladdin--the rich reward of the countless marauding operations of Bennett's other personality.

For a moment they could merely stand in avaricious exultation.

Painfully and slowly, we managed to trail Long Sin's footprints, until we came to a road where they were lost in the hard macadam. There was no time to stop. We must follow the road on the chance that he had taken it. But which way?

Kennedy chose the most likely direction, for the trail had been at an angle to the road and Long Sin was not likely to double back. We had not gone many rods before Kennedy paused a minute and looked about in the moonlight.

"It's right, Walter," he cried. "Do you recognize it?"

I looked about. Then it flashed over me. This was the back road that led past the entrance to the treasure vault at Aunt Tabby's.

We went on now more quickly, listening carefully to catch any sounds, but heard nothing. At last Kennedy stopped, then plunged among the rocks and bushes beside the road. We were at the cave.

"You go in this way, Walter," he directed. "I'll go around and down where it caved in."

I groped my way along through the darkness.

I had gone only a yard or two, when it seemed as though something had grasped my foot.

With a great wrench I managed to pull it loose. But the weight on my other foot had imbedded it deeper. I struggled to free this foot and got the other caught. My revolver, which I had drawn, was jarred from my hand and in the effort to recover it, I lost my balance. Unable to move a foot in time to catch myself, I fell forward. My hands were now covered by the slimy, sticky stuff, and the more I struggled, the worse I seemed to get entangled.

Wu and Long Sin paused only a minute in astonishment. Then they literally fell upon the wealth that lay before them, gloating over the gold, stuffing their hands into the jewels, lifting them up and letting the priceless gems run through their fingers.

Suddenly they paused. There was the slight tinkle of a Chinese bell.

Kennedy had reached Aunt Tabby's garden, outside the roof of the subterranean chamber where it had given way, had gone down carefully over the earth and rock, and in doing so had broken a string stretched across the pa.s.sageway. The tinkle of a bell attached to it aroused his attention and he stopped short, a second, to look about. Wu Fang had arranged a primitive alarm.

Quickly, Wu and Long Sin blew out their lanterns while Wu gave the rock a push. Slowly, as it had opened, it now closed and they stood there listening.

I was still struggling in the bird lime, getting myself more and more covered with it, when the reverberation of revolver shots reached me.

Wu and Long Sin had opened fire on Kennedy, and Kennedy was replying in kind. In the cavern it sounded like a veritable bombardment. As they retreated, they came nearer and nearer to me and I could see the revolvers spitting fire in the darkness. So intent were they on Kennedy that they forgot me.

I watched them fearfully as they hopped deftly from one stone to another to avoid the lime--and were gone.

"Craig! Craig!" I managed to cry feebly. "Be careful. Keep to the stones."

He strained his eyes toward the ground in the darkness, at the sound of my voice. Then he struck a match and instantly took in the situation which, to me, under any other circ.u.mstances, would have been ludicrous.
