In a wild frenzy of exertion she put forth an effort of which she would not have believed herself capable. The board gave way so abruptly that she almost fell upon the floor. The next moment she was on the verge of fainting. Before her was naught but the brickwork of the wall. Yet, stay, here the bricks had been removed for a little space and relaid without mortar. She gouged them out again after the fashion of the marauder, and behind them saw into the interior of the pilaster. The cavity was flush with the floor. She thrust in her hand, nothing! Still further with like result. She flung herself down upon the floor and ran her arm in to its extreme length. She touched a fluffy, disintegrated mass, sere leaves it might have been, feathers or fur. Her dainty fingers tingled with repulsion as they closed upon it. She steadily pulled it forward, and, oh, joy, she felt a weight, a heavy weight. She thrust in both arms and drew toward her slowly, carefully--a footfall on the stair, was it? Still slowly, carefully, the tattered remnants of an old knapsack, and a box, around which it had been wrapped. A metal box it was, of the style formerly used, inclosed in leather as jewel-cases, locked, bound with steel bands, studded with brass rivets, intact and weighty. Paula sprang up with a bound. For one moment she paused with the burden in her arms, doubting whether she should conceal the chest anew or dare the stairs. The next, as silent as a moonbeam, as fleet as the gust that tossed her skirts, she sped around the twists of the spiral turns and reached the second story. She looked over the balustrade, no light, save the moonbeams falling through the great doorless portal, no sign of life; no sound. But hark, the gnawing of a patient chisel, and presently the fibrous rasping of riving wood came from the empty apartments on the left. Still at work were the marauders, and still she was safe. She continued her descent, silently and successfully gaining the entresol, but as she turned to essay the flight to the lower hall she lost the self-control so long maintained, so strained. Still at full speed she came, silent no longer, screaming like a banshee. Her voice filled the weird old house with shrill horror, resounding, echoing, waking every creature that slept to a frenzied panic, and bringing into the hall all the men of the steamboat’s party, half dressed, as behooves a “shake-down.” The women, less presentable, held their door fast and clamored out alternate inquiry and terror. “I have found it! I have found it!” she managed to articulate, wild-eyed, laughing and screaming together, and rushing with the box to the astonished Ducie, she placed it in his hands. “And, oh, the house is full of robbers!”
