The only danger was that the beast would discover the method of releasing the catch; but Bry happened to have a small Yale lock in his pocket, so we unearthed a heavy bronze chain from one of the alcoves, and by tossing an object inside the niche induced Fo-Chu to dive for it. This gave us a chance to snap the lock through its links.

Knowing we were now masters of the situation we proceeded to the tomb of Kai Abon and examined it with care. It yielded us about two quarts of superb rubies, besides three dozen magnificent pearls and the great beryl. From there we visited the place where Mai Lo had been assorting his jewels, but found he had removed the heap and secreted his treasure elsewhere. The vault of the third Kai, however, contained a vast store of fine gems, and after we had secured these and added them to the treasure already acquired, we were well satisfied with the result of our night’s adventure.

Before we returned along the passage we went to take another look at the Sacred Ape. He was squatting upon the floor of his alcove, motionless but alert, and by the lamplight I thought his eyes glowed like two great rubies.

CHAPTER XXVII.
THE BATTLE IN THE CORRIDOR.

When we reached our rooms and behind bolted doors examined the contents of the tapestry curtain, we were amazed at the splendor of the treasure we had obtained.

“But it isn’t on board the Seagull yet,” Joe reminded us, and we sighed regretfully as we realized the truth of this statement. Nux took charge of the booty and then we all went to bed and tried to sleep; but on my part the attempt was not very successful. I wakened every little while with a start to see the glowing eyes of the great ape regarding me from the darkness, or the great gray body hurtling through the air to fall upon me; and my cheek pained me from the deep gash it had received.

So I slept but fitfully until daybreak, when I rose to find Archie and Joe already up and Bryonia making coffee over an alcohol stove.

Our first care was to dispose of the jewels, and this we did by tearing the leaves out of some of the books of Prince Kai, a big heap of which had been sent us by the eunuch, and wrapping the gems in them. Afterward we packed two boxes with them and nailed on the covers. To carry out the deception we had planned, we next concealed in the empty drawers of the cabinet enough ornaments to have filled the two boxes.

So far our work had progressed very well, and we had just finished breakfast and were congratulating ourselves on our progress when our eunuch Tun ran in and told us that the governor’s troops had been ordered to advance upon our retreat and capture us in our rooms.

“Send for Wi-to at once,” I commanded.
