The members of our party, catching something of my hope, were ready to enter at once upon this task, and it was decided to divide all our forces into two companies, one to be led by the doctor and the other by me, and then to start in different directions to try to find the entrance to that long passage into the interior. As we knew not on what part of the moon’s surface we had alighted, we were undertaking a bold piece of work, but its apparent difficulty had no terrors for the Martians, and I should not have hesitated if the circumference of the moon had been a hundred times what it was. As for the doctor, he had too much spirit to suggest any obstacles. We arranged a code of signals, and agreed that if either party were successful the other should be notified and the descent made only when all had come together. After dividing the provisions we made our adieus and separated, not knowing when we should see one another again. But, fortunately, our elaborate preparations were not of much use, for before we had been out an hour the doctor signaled to me that he had found some familiar landmarks. This meant that he was sure of discovering what we were in search of, and accordingly we started at once to rendezvous with his company. On our arrival I recognized, with exultant joy, the features of the landscape which had attracted the doctor’s attention. We now led the way with complete assurance, and came at length to the crater down whose side Mona had so strangely led us. The wind was not so strong now, but I was none the less eager to descend and enter that dark way, at the other end of which such happiness awaited me. By this time, also, the whole party were becoming enthused over the situation. When they came to see, one after another, features which they had heard us describe, they acquired a personal interest which had been impossible before, and everyone began to share my faith in regard to Mona. As we entered the tunnel, the doctor and myself still in the lead, I called Avis and asked her to keep as near me as possible. “I am flattered,” she said, “but what do you want to have me do?” “Sing,” I answered. “What for? You needn’t be afraid of the dark, for we can give you light enough.” And at that instant out flashed half a dozen lamps from different members of the party, a timely illustration of the use of their portable electricity. “No, Avis,” I said, “I am not afraid, but I would like to recall something of the sensation of our first descent into the moon, when we were led, as you know, by the sound of beautiful music. And then, as we near the end, Mona may hear you, and that would be a more gentle introduction than if we should burst upon her unannounced. I know she is not subject to fear or the usual emotions to which I have been accustomed on the earth, but still I think she would like to have us come back to her heralded by your noble song.”
