"All of us whom you brought to Njambai," I proceeded, "are changed men. To you alone we owe this, and I wish to go on record, here and now, for giving you credit. I see my past as I thought I never should see it, and I realize how I have wasted a large part of my life. I shall prove a worthy citizen, if we succeed in getting back to Earth, and it is you who have brought about my reformation." A glow came to the professor’s face. He held up one hand protestingly. "It is the truth," I insisted. "You have argued with me constantly ever since we were thrown together, and it was while on the road to Baigol that the truth of your arguments suddenly came home to me." I stretched out my hand, but he held back. "You are too shrewd a man, Mr. Munn," said he kindly, "to be so deceived. There have been times when your artlessness made me wonder, but you have never aroused my wonder quite so much as you have now." "Why is that?" I asked, puzzled. "Answer me this, Mr. Munn," he went on. "How did it chance that Mr. Gilhooly so suddenly recovered his reason?" "He lost his wits suddenly, and crazed people have been known to regain their sanity as quickly as they lost it. It must have been so in Gilhooly’s case." "Indeed!" he said, smiling. "And was it merely a coincidence that you found your conscience, and Gilhooly his reason, at the same time?" "Merely a coincidence," I replied. He laughed, and it was his first happy laugh since King Gaddbai had announced his coming campaign in the direction of Terra. "Let us go further," he went on. "What caused Markham, Popham and Meigs to change their points of view so miraculously? Was it the coal mines, the lack of food and the need of decent clothing?" "All that merely paved the way," I averred. "Your arguments did the rest." "You are blind, Mr. Munn! It was not the sufferings our friends endured, nor my arguments." "Then what was it?" I demanded. "The Bolla!" I recoiled, staring blankly at the kindly face before me. "Don’t let me part from you, Professor Quinn," I whispered hoarsely, "feeling that I have left behind a man of unsound mind! If I thought that, I believe I should remain here with you at any cost."
