Norton went below and returned with a glass jar in which to carry the water and the balance of us lined the rail with our service revolvers ready in the event of an emergency as he went over the side. None of us had walked more than a few steps since coming on deck after our landing. I had noticed a slightly peculiar sensation of buoyancy, but in view of the numerous other distractions had given it no consideration. As Norton reached the bottom of the ladder and set foot on lunar soil I called to him to make haste. Just in front of him was a low bush and beyond it lay the river, about thirty feet distant. In response to my command he gave a slight leap to clear the bush and, to our amazement as well as to his own consternation, rose fully eighteen feet into the air, cleared a space of fully thirty- five feet and lit in the river. “Come!” I said to the others, wishing them to follow me to Norton’s aid, and sprang for the rail; but I was too impetuous. I never touched the rail, but cleared it by many feet, sailed over the intervening strip of land, and disappeared beneath the icy waters of the lunar river. How deep it was I do not know; but at least it was over my head. I found myself in a sluggish, yet powerful current, the water seeming to move much as a heavy oil moves to the gravity of Earth. As I came to the surface I saw Norton swimming strongly for the bank and a second later Jay emerged not far from me. I glanced quickly around for West, whom I immediately perceived was still on the deck of _The Barsoom_, where, of course, it was his duty to remain, since it was his watch. The moment that I realized that my companions were all safe I could not repress a smile, and then Norton and Jay commenced to laugh, and we were still laughing when we pulled ourselves from the stream a short distance below the ship. “Get your sample, Norton?” I asked. “I still have the container, sir,” he replied, and indeed he had clung to it throughout his surprising adventure, as Jay and I, fortunately, had clung to our revolvers. Norton removed the cap from the bottle and dipped the latter into the stream. Then he looked up at me and smiled. “I think we have beaten Mr. West to it, sir,” he said. “It seems like very good water, sir, and when I struck it I was so surprised that I must have swallowed at least a quart.” “I tested a bit of it myself,” I replied. “As far as we three are concerned, Mr. West’s analysis will not interest us if he discovers that lunar water contains poisonous matter, but for his own protection we will let him proceed with his investigation.” “It is strange, sir,” remarked Jay, “that none of us thought of the natural effects of the lesser gravity of the Moon. We have discussed the matter upon many occasions, as you will recall, yet when we faced the actual condition we gave it no consideration whatsoever.”
