Nux and I sitting half asleep by the mouth of the cave, were warned by the first chill blast that swept over us that the weather had changed and a storm was imminent. Springing to my feet I looked fearfully at the darkening sky.

“What’ll we do, Nux?” I asked. “This will bring our enemies back here in double-quick time.”

“Better climb on top de rock, Mars Sam,” advised the Sulu.

“But it’ll rain—floods and torrents, probably—and thunder and lightning besides.”

“’Spect it will, Mars Sam. But rain won’t hurt us much.”

“And Daggett’s gang will, if they catch us. I guess you’re right, Nux. Come along.”

As we started along the ledge the wind came upon us in sudden gusts, and the sky grew so dark that we almost had to feel our way. It was necessary to exercise great care, both to find a secure footing and to cling fast to the face of the rock, to prevent our being blown into the abyss below; but we struggled manfully on, and presently reached the top, where Nux hoisted me over the edge and then scrambled after me.

By this time the lightning was playing all around us, and we were obliged to crawl carefully on hands and knees to the little hollow in the center of the rock, where we were to an extent shielded from the fierce gusts of wind. Even then I feared we would be blown away; but Nux shouted in my ear to hold fast to the gold, which served as a sort of anchor, and enabled us both, as we lay flat in the hollow, to maintain our positions securely.

And now the lightning began to be accompanied by sharp peals of thunder, while the wind suddenly subsided to give place to wild floods of rain. At intervals could be heard the shouts of the robbers, who had reached the rocks and were creeping along the ledge to their cave. All the elements seemed engaged in a confused turmoil, until I was nearly deafened by the uproar. I tried to ask a question of Nux, but could not hear my own voice, and gave up the attempt. The thought crossed my mind that we had been very foolish to climb to this peak of rock, where we were exposed to the full fury of the storm, and I wondered vaguely, as I clung to the sack of gold we had risked so much to secure, how long it would be before the wind swept us away, or we would be annihilated by a bolt of lightning.

Presently an arm was laid across my back, as if to protect me, and raising my head I saw by the light of a vivid flash that Bryonia had joined us and was lying in the hollow at my side.
