I was anxious to visit Tentholm, for I feared that much of our precious stores might have suffered. Fritz and I made an excursion thither. The damage done to Falconhurst was as nothing compared to the scene that awaited us. The tent was blown to the ground, the canvas torn to rags, the provisions soaked, and two casks of powder utterly destroyed. We immediately spread such things as we hoped yet to preserve in the sun to dry. The pinnace was safe, but our faithful tub-boat was dashed in pieces, and the irreparable damage we had sustained made me resolve to contrive some safer and more stable winter-quarters before the arrival of the next rainy season. Fritz proposed that we should hollow out a cave in the rock, and though the difficulties such an undertaking would present appeared almost insurmountable, I yet determined to make the attempt; we might not, I thought, hew out a cavern of sufficient size to serve as a room, but we might at least make a cellar for the more valuable and perishable of our stores. Some days afterward we left Falconhurst with the cart laden with a cargo of spades, hammers, chisels, pickaxes, and crowbars, and began our undertaking. On the smooth face of the perpendicular rock I drew out in chalk the size of the proposed entrance, and then, with minds bent on success, we battered away. Six days of hard and incessant toil made but little impression; I do not think that the hole would have been a satisfactory shelter for even Master Knips; but we still did not despair, and were presently rewarded by coming to softer and more yielding substance; our work progressed, and our minds were relieved. On the tenth day, as our persevering blows were falling heavily, Jack, who was working diligently with a hammer and crowbar, shouted: "Gone, father! Fritz, my bar has gone through the mountain!" "Run round and get it," laughed Fritz; "perhaps it has dropped into Europe--you must not lose a good crowbar." "But, really, it is through; it went right through the rock; I heard it crash down inside. Oh, do come and see!" he shouted excitedly. We sprang to his side, and I thrust the handle of my hammer into the hole he spoke of; it met with no opposition, I could turn it in any direction I chose. Fritz handed me a long pole; I tried the depth with that. Nothing could I feel. A thin wall, then, was all that intervened between us and a great cavern. With a shout of joy, the boys battered vigorously at the rock; piece by piece fell, and soon the hole was large enough for us to enter. I stepped near the aperture, and was about to make a further examination, when a sudden rush of poisonous air turned me giddy, and shouting to my sons to stand off, I leaned against the rock.
