Then, carefully wrapping the ancient badge of regal dignity in a piece of hide and binding it securely with wire as the carriers' loads had been, I gave it back to her. In half an hour we had completed our examination of the wondrous accumulation of treasure, finding among it many quaint and extraordinary ornaments, some no doubt dating from the earlier days of the foundation of the mysterious isolated kingdom, and others manufactured during recent centuries. The gems were unique in size and character. Truly the thieves in the employ of the Arab chief had taken care to secure the most valuable portion of the royal jewels and leave behind only those of least worth.

With the secret of their concealment in our possession we were both full of eagerness to get back to the light of day and take steps for their removal, yet I confess that the mystery of what was contained behind those strange plates of iron puzzled me.

Leaving Liola to continue her inspection of our discovered treasures, I crossed to the wall and examined one of the plates again, trying with both hands to force it out, but being compelled to relinquish the attempt as hopeless. I was about to give up all idea of discovering how they might be opened, when Liola suddenly uttered an exclamation, and in turning to glance at her, the flame of the lamp I held came into contact with the wall close to the plate that had defied my exertions to remove it.

In an instant a bright flash ran around the chamber, lighting it up as bright as day; a puff of grey smoke was belched in our faces, and a report like thunder deafened us.

An explosion had occurred, great pieces of rock and other débris being flung in all directions.

Its terrific force hurled me heavily against the wall, while Liola was flung face downward upon the pile of jewels. Fortunately, neither of us sustained any injury beyond a few bruises, but when I had assisted her to rise, and gazed around, I was amazed to discover that a strange thing had occurred. The whole of the iron plates had been torn from their sockets, and a dark cavity behind each disclosed.

The small sealed cells had been wrenched open simultaneously, as if by a miracle.

But upon careful examination there was, I found, nothing miraculous in the manner in which they had thus been forced. The suffocating smoke that filled the place was of itself sufficient evidence of the agent to which the explosion had been due, and when I looked at the first cavity I saw that right around the chamber, from plate to plate, there had been laid a train of gunpowder, communicating with a charge of powder placed behind each of the semi-circular holes that had so puzzled me. Apparently it had been deemed by Samory wiser to seal the cells entirely rather than secure them by locks, and the train of powder had been placed in position in the event of any reverse of fortune requiring him to secure his treasure quickly before flight. A single spark, as I had accidentally proved, was sufficient to open every cell simultaneously.

Fortunately our lamp was not blown out by the concussion, therefore as soon as the smoke cleared, we together made another tour of inspection around the cavities, finding each of them crammed to overflowing with treasure of every description. Five of the cells, apparently freshly sealed, contained a portion of the stolen jewels of Mo, but all the remainder were evidently the spoils of war, much of it of enormous value. It amused me, too, to discover in one of the cavities, among a great collection of costly bejewelled ornaments, such European articles as a pair of common scissors in a pasteboard case, several penknives of the commonest quality, an India-rubber squeaking doll, a child's toy train in tin, and a mechanical mouse. All were, no doubt, considered as treasures by the Arab potentate, yet I reflected that nearly every article in the whole of that miscellaneous collection had been acquired by the most ruthless and merciless bloodshed.

When at last we became convinced of the necessity for finding some exit, we left the chamber by the way we had entered. The discovery of the wonderful treasure of the Sanoms made it plain to me that there must be an exit somewhere, for the packs were far too ponderous to have been lowered from the Kasbah by the way we had entered. On reflection I saw that the lion was evidently kept there to guard the entrance to the store of treasure, therefore it was not surprising that there was no outlet in that direction.
