Our first experience in the internal sphere was that of a sudden storm. The sun grew dark and appeared like a disc of sombre gold. The ocean was lashed by a furious hurricane into incredible mountains of water. Every crest of the waves seemed a mass of yellow flame. The internal heavens were rent open with gulfs of sulphur-colored fire, while the thunder reverberated with terrible concussions. The ship would spin upon the water as though every wave were a whirlpool. A golden-yellow phosphorescence covered the ocean. The water boiled in maddening eddies of lemon-colored seas, while from the hurricane decks streamed cataracts of saffron fire. The lightning, like streaks of molten gold, hurled its burning darts into the sea. Everything bore the glow of amber-colored fire. The sailors congratulated themselves on the shelter provided by the deck overhead. The motion of the ship exceeded all former experiences, for it leaped and plunged in a terrific manner. It was a question whether we would survive the storm or not, so violent was the shaking up both ship and men received. Fortunately, the loss of weight in everything, which was the cause of the rapid motion, permitted no more damage than would be caused by a lesser storm on heavier objects. The professor stated that he believed the tempest was occasioned by a polar tidal wave of air rushing into the interior sphere, to supply the exhaustion caused by outgoing warm currents, owing perhaps to a periodical overheating of the air by the internal sun. When a certain volume of the air was expelled, so that it could no longer resist external pressure, then the external air rushed down the polar gulf, creating by meeting warm outward-flowing currents cyclones such as we were then experiencing. By degrees the storm abated, the sea grew calm, the heavens above us became clearer, and the sun assumed the rose-color he first presented to our gaze, standing right in the zenith. The only damage done to the crew was a few broken limbs and some severe bruises. The ship had lost several spars, and one of her boats was blown out of its lashings on deck and was lost. It was a week since we had left the outer world, and what a change had occurred in that short space of time! The excitement had been so intense that not a man of us had slept during that period, and as for meals, we had forgotten about them altogether. A general order was given the cooks to prepare a banquet to duly inaugurate our discovery of the new world. Both officers and men, including myself, sat down at the same table, where we satisfied the cravings of a week's hunger. I expressed my heartfelt pleasure in the safety of the crew and ship so far in making so tremendous a discovery. I relied on the courage and loyalty of the crew for still further explorations in the strange and mysterious planet we had discovered. I declared that those who shared the dangers of the expedition would also share in whatever reward fortune might bestow upon us.
