"Because Saturn is so far away from the Sun," replied Mary. "Next to Saturn we find Uranus. This planet was first seen by William Herschel, who afterwards became one of the greatest astronomers the world has ever known. When Herschel was a little boy his home was in Hanover. He had great talent for music, and when he was fourteen years old he joined the band of the Hanoverian Guards. What a proud boy he was when he dressed in his new uniform! However, pride must have a fall, and it was not very long before he wished he had never entered the army. Just about this time war broke out between France and England, and as Hanover belonged to the English it was attacked by the French. The Hanoverian Guards were badly defeated. Herschel spent the night after the battle hiding away in a ditch, and next day, assisted by his friends, he ran away to England. There he continued his musical studies, and some years later he became a fine organist." "Did he have to play a big organ like the one in our church?" asked Harry. "Something like that, I suppose," said Mary; "and he played very well indeed. He learned more and more about music, and in the evenings when going and coming from the church he used to notice the beautiful stars overhead, and he wished to learn something about them." "Just the way I feel," said Harry. "I get nurse to pull up the window curtain at night so that I can see the stars from my bed, and they seem to laugh and wink their little eyes at me as if they knew I was watching them. Did Herschel have a telescope like the one Uncle Robert has?" "He was not so fortunate, but he wanted one very much indeed. So he borrowed a telescope from a friend, and every night after practicing in the church he would amuse himself looking at the stars. He longed to have a telescope of his own; but he found that they cost more than he could afford to pay, so he decided to make one. He bought all that was necessary, and turned his home for the time into a workshop. He had a dear, good-natured sister named Caroline, and she did all she could to help her brother. Sometimes he was too busy to eat and she used to feed him. When he was tired she would read to him from the 'Arabian Nights.'" "The same book I have?" asked Harry, in surprise. "The very same; and this helped to pass away the time while Herschel polished away on the great mirror of his telescope. When the telescope was finished people came from far and near to see it. One evening when Herschel was gazing at the stars with this magic glass he spied a star not marked down on his charts. 'Something wrong here,' thought Herschel; 'this must be a comet.' But after noticing it for a while he found that it was not a comet, but a planet or wanderer among the stars." DIFFERENCE BETWEEN A PLANET AND A STAR. "How could he tell the difference?" asked Harry. "When I looked at Planet Jupiter last night it looked like the stars, only rounder and bigger."
