"Very likely," replied Mary; "and perhaps you would like me to tell you what those black marks are. They are enormous plains and gloomy caverns on the moon. A long time ago, perhaps, these plains were bays and seas. At least, a great astronomer named Galileo thought they were, and he gave them such pretty names—the Sea of Serenity, the Bay of Dreams, the Ocean of Storms. But he lived in the days before it was known that there is not any water on the surface of the moon. Then the caverns on the moon may once have been volcanoes pouring forth hot lava and ashes, just as the active volcanoes on the earth. But the volcanoes in the moon have gone out. They are now like huge dark caverns, some of them more than fifty miles across. One is three miles deep, and it is named Tycho, after a great astronomer of olden times.
"Then there are mountains on the moon just like the mountains on earth, and quite as high. In walking over the moon you would find it very rough and uneven, but you would not mind this very much, as you would weigh so much less. Just think, Harry, you would weigh only one-sixth as much as you do here."
"And what would Uncle Robert weigh?" asked Harry, with a gleam of mischief in his eye.
