CHAPTER XX.—THE LAST STRAW.

A glance—more he did not dare bestow whilst confronted by that treacherous throng—showed Jack what he and Don had hitherto entirely failed (and no wonder!) to observe. In the extreme corner of the ledge on which they stood, a deep, narrow gash divided the towering side wall, and up this, clear to the summit of the rock, there ran a flight of steps. On these Bosin had perched himself. At their foot crouched the blacks, blind to everything except their own danger. .

“Wake those niggers up, and start them on ahead up the steps!” said Jack quickly. “Look sharp! they're going to rush us again.”

Falling on Spottie and Puggles, by dint of vigorous cuffing and shoving Don succeeded in getting them on the stairs. Rapidly as this was done, it produced an instantaneous effect upon the native rabble. They too had overlooked the existence of the stairway until Don's action recalled it to mind. A moment later the opening was besieged by a clamouring, infuriated throng.

“Up with you, old fellow!” cried Jack, turning on the natives with drawn cutlass after he had ascended some half-dozen steps, and thus covering his friend's retreat. “You had your innings at the pit; now it's my turn.”

Stationed on the steps as he was, Jack would have possessed no mean advantage over the natives but for one circumstance. The chain attached to his leg dangled down the steps, and the natives, discovering this, promptly seized it. In a twinkling Jack was dragged back into the midst of the furious rabble.

Don was half-way up the steps when the uproar caused by this mishap reached his ears. He turned just in time to see his companion disappear.

Down the steps he bounded, clearing half-a-dozen at a leap, until barely that number lay between him and the bottom, where, owing to Jack's desperate resistance, the natives had their hands too full to notice his approach. Gauging the distance with his eye, he took a flying leap from this height into the very midst of them, scattering them in all directions. As he intended, he overleapt his friend, who now quickly regained his feet. Before the natives had time to recover from the shock of Don's precipitate arrival in their midst, he and Jack were well up the steps again. One or two of the gang made as if to follow them, but turned tail when menaced with the cutlasses.
