"That was a clever little toad," said Harry, laughing; "and how vexed Mr. Wolf must have been! Are there any more people on the moon--I mean story people?" "Yes, there is one we read about in the legend of Hiawatha. Don't you remember how Nokomis tells about a warrior "'... Who very angry Seized his grandmother, and threw her Up into the sky at midnight, Right against the moon he threw her: 'Tis her body that you see there.'" "Do you think he meant the black marks you can see all over the moon, sister?" [Illustration: EARTH AS SEEN FROM THE MOON.] SCENERY ON THE MOON. "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. [Illustration: PLANET EARTH AND THE MOON.] "He would only weigh forty pounds," said Mary, laughing; "and if he played football on the moon, a good kick would send the ball six times as far away as here. Supposing we were on the moon now, you could throw a stone at Uncle Robert's house on the other side of the grounds, six hundred yards away, and hit one of the windows." "I expect Uncle Robert may be glad then we are not on the moon," said Harry, laughing; "because I am afraid I should be throwing stones at the windows all the time. I can see the windows plainly from here. There is a light in the library." "Then it must be very late," said Mary, looking over at the house; "because uncle said he would not be home till nine o'clock. So I can only tell you one more little story about the moon, and then I must let you go to sleep. This story is told by the Hindoo people, and gives the reason why the moon shines with such a soft, silvery light." THE HINDOO LEGEND.
