Her face brightened. "I am so glad!" she said. "I have studied nothing else for months. It has been so almost from the day you left us. And it is not Mars alone I am studying; it is the great problem of communication with the people there. Oh, Julius, it is possible, and the idea is something wonderful! Just think what would follow! It would be the beginning of an understanding between reasoning creatures of the whole universe!"

He said that it was something wonderful, indeed, maybe only a dream, but a very fascinating one.

"Oh, it is no dream," she answered. "It is a glorious possibility. Why, just think of it, we know, positively know, that Mars is inhabited. Think of what has been discovered. It was perceived years ago that Mars was intersected by canals, evidently made by human—I suppose that's the word—human beings. They run from the extremes of ocean bays to the extremes of other ocean bays, and connect, too, the many lakes there. Nature does not make such lines. They are of equal width, those canals, throughout their whole length, and Schiaparelli has even watched them in construction. First there is a dark line, as if the earth had been disturbed, and then it becomes bright when the water is let in. Sometimes, too, double canals are made there close to each other, running side by side, as if one were used for travel and transportation in one direction and one in another. And there are many other things as wonderful. The world of Mars is like our own. There are continents and seas and islands there—it is not a dead, dry surface like the moon—and it has clouds and rains and snows and seasons, just as we have, and of the same intensity as ours. Oh, Julius, we must communicate with them!"

"But, my dear, that implies equal interest on their part. How do we know them to be intelligent enough?"

"Why, there are the canals. They must be reasoners in Mars. Besides, how do we know but that they far surpass us in all learning! Mars is much older in one way than the Earth, far more advanced in its planet life, and why should not its people, through countless ages of advantage, have become wiser than we? Whatever their form, they may be superior to us in every way. We are to them, too, something which must have been studied for thousands of years. The Earth, you know, is to the people on Mars a most brilliant object. It is the most glorious object in their sky, a star of the first magnitude. Oh, be sure their astronomers are watching us with all interest!"

And Corbett, dazed, replied that he was overwhelmed with so much learning in one so fair, that he was very proud of her, but that there was one subject on his mind, compared to which communication with Mars or any other planet was but a trifle. And he wanted to talk with her concerning what was closest to his heart. It was the one great question in the world to him. It was, when should be their wedding day?

The girl looked at him blushingly, then paled. "Let us not talk of that to-day," she said, at length. "I know it isn't right; I know that I seem unkind—but—oh, Julius! come to-morrow and we will talk about it." And she began crying.

He could not understand. Her demeanor was all incomprehensible to him, but he tried to soothe her, and told her she had been studying too hard and that her nerves were not right. She brightened a little, but was still distrait. He left, with something in his heart like a vengeful feeling toward the planets, and toward Mars in particular.

When Corbett returned next day the girl was in the library awaiting him. Her demeanor did not relieve him. He feared something indefinable. She was sad and perplexed of countenance, but more self-possessed than on the day before. She spoke softly: "Now we will talk of what you wished to yesterday."

He pleaded as a lover will, pleaded for an early day, and gave a hundred reasons why it should be so, and she listened to him, not apathetically, but almost sadly. When he concluded, she said, very quietly:
