But he was not worried. The professor loved Huyck as a visionary and smiled not a little at his delightful fancies. Doubtless this was one of them. It was not until the news came flashing out of Oakland that he began to take it seriously. Then followed the disappearance of Mount Heckla. “If the world goes up”—it began to look as if the words had meaning. There was a frantic professor during the next few days. When he was not with the lens he was flashing out messages to the world for Charley Huyck. He did not know that Huyck was lying unconscious and almost dead upon the desert. That the world was coming to catastrophe he knew full well; but where was the man to save it? And most of all, what had his friend meant by the words, “look these up”? Surely there must be some further information. Through the long, long hours he stayed with the lens and waited. And he found nothing. It was three days. Who will ever forget them? Surely not Professor Williams. He was sweating blood. The whole world was going to pieces without the trace of an explanation. All the mathematics, all the accumulations of the ages had availed for nothing. Charley Huyck held the secret. It was in the stars, and not an astronomer could find it. But with the seventeenth hour came the turn of fortune. The professor was passing through the office. The door was open, and the same fitful wind which had played the original prank was now just as fitfully performing restitution. Williams noticed a piece of paper protruding from the back of the bookcase and fluttering in the breeze. He picked it up. The first words that he saw were in the handwriting of Charley Huyck. He read: “In the last extremity—in the last phase when there is no longer any water on the earth; when even the oxygen of the atmospheric envelope has been reduced to a minimum—man, or whatever form of intelligence is then upon the earth, must go back to the laws which governed his forebears. Necessity must ever be the law of evolution. There will be no water upon the earth, but there will be an unlimited quantity elsewhere. “By that time, for instance, the great planet, Jupiter, will be in just a convenient state for exploitation. Gaseous now, it will be, by that time, in just about the stage when the steam and water are condensing into ocean. Eons of millions of years away in the days of dire necessity. By that time the intelligence and consciousness of the earth will have grown equal to the task. “It is a thing to laugh at (perhaps) just at present. But when we consider the ratio of man’s advance in the last hundred years, what will it be in a billion? Not all the laws of the universe have been discovered, by any means. At present we know nothing. Who can tell?
