I saw that we must apply some more efficacious remedy, and sent the boys for a chest of signal-rockets we had brought from the wreck. We let fly some dozens of these fiery serpents, which went whizzing in and disappeared at apparently a vast distance from us. Some flew like radiant meteors round, lighted up the mighty circumference and displayed, as by a magician's wand, a sparkling glittering roof. They looked like avenging dragons driving a foul malignant fiend out of a beauteous palace.
We waited for a little while after these experiments, and I then again threw in lighted hay. It burned clearly; the air was purified.
Fritz and I enlarged the opening, while Jack, springing on his buffalo, thundered away to Falconhurst to bear the great and astonishing news to his mother.
Great must have been the effect of Jack's eloquence on those at home, for the timbers of the bridge were soon again resounding under the swift but heavy tramp of his steed; and he was quickly followed by the rest of our party in the cart.
All were in the highest state of excitement. Jack had stowed in the cart all the candles he could find, and we now, lighting these, shouldered our arms and entered. I led the way, sounding the ground as I advanced with a long pole, that we might not fall unexpectedly into any great hole or chasm.
Silently we marched—my wife, the boys, and even the dogs seeming overawed with the grandeur and beauty of the scene We were in a grotto of diamonds—a vast cave of glittering crystal; the candles reflected on the walls a golden light, bright as the stars of Heaven, while great crystal pillars rose from the floor like mighty trees, mingling their branches high above us and drooping in hundreds of stalactites, which sparkled and glittered with all the colours of the rainbow.
The floor of this magnificent palace was formed of hard, dry sand, so dry that I saw at once that we might safely take up our abode therein, without the slightest fear of danger from damp.
From the appearance of the brilliant crystals round about us, I suspected their nature. I tasted a piece. This was a cavern of rock-salt. There was no doubt about it—here was an unlimited supply of the best and purest salt!
But one thing detracted from my entire satisfaction and delight—large crystals lay scattered here and there, which, detached from the roof, had fallen to the ground; this, if apt to recur, would keep us in constant peril. I examined some of the masses and discovered that they had been all recently separated, and therefore concluded that the concussion of the air, occasioned by the rockets, had caused their fall. To satisfy ourselves, however, that there were no more pieces tottering above us, we discharged our guns from the entrance, and watched the effect.
Nothing more fell—our magnificent abode was safe. We returned to Falconhurst with minds full of wonder at our new discovery, and plans for turning it to the best possible advantage.
