“A labour-saving device for mariners, navigation reduced to kindergarten simplicity,” he answered gaily. “From to-day a child will be able to navigate a ship. No more long-winded calculations. All you need is one star in the sky on a dirty night to know instantly where you are. Look. I place the transparent scale on this star-map, revolving the scale on the North Pole. On the scale I’ve worked out the circles of altitude and the lines of bearing. All I do is to put it on a star, revolve the scale till it is opposite those figures on the map underneath, and presto! there you are, the ship’s precise location!” There was a ring of triumph in his voice, and his eyes, clear blue this morning as the sea, were sparkling with light. “You must be well up in mathematics,” I said. “Where did you go to school?” “Never saw the inside of one, worse luck,” was the answer. “I had to dig it out for myself.” “And why do you think I have made this thing?” he demanded, abruptly. “Dreaming to leave footprints on the sands of time?” He laughed one of his horrible mocking laughs. “Not at all. To get it patented, to make money from it, to revel in piggishness with all night in while other men do the work. That’s my purpose. Also, I have enjoyed working it out.” “The creative joy,” I murmured. “I guess that’s what it ought to be called. Which is another way of expressing the joy of life in that it is alive, the triumph of movement over matter, of the quick over the dead, the pride of the yeast because it is yeast and crawls.” I threw up my hands with helpless disapproval of his inveterate materialism and went about making the bed. He continued copying lines and figures upon the transparent scale. It was a task requiring the utmost nicety and precision, and I could not but admire the way he tempered his strength to the fineness and delicacy of the need. When I had finished the bed, I caught myself looking at him in a fascinated sort of way. He was certainly a handsome man—beautiful in the masculine sense. And again, with never-failing wonder, I remarked the total lack of viciousness, or wickedness, or sinfulness in his face. It was the face, I am convinced, of a man who did no wrong. And by this I do not wish to be misunderstood. What I mean is that it was the face of a man who either did nothing contrary to the dictates of his conscience, or who had no conscience. I am inclined to the latter way of accounting for it. He was a magnificent atavism, a man so purely primitive that he was of the type that came into the world before the development of the moral nature. He was not immoral, but merely unmoral.
