THE BULL, AND THE PLEIADES.
"But there are not any animals really in the sky, are there?" said Harry.
"No," said Mary, laughing at the question; "but if you look at the stars you can imagine you see outlines of bulls and serpents and all kinds of strange animals. Only you have to imagine very much, and this is exactly what the Grecians did.
"In the shoulder of the bull is the pretty little cluster of stars known as the Pleiades."
STORY OF THE PLEIADES.
"What is a cluster of stars?" asked Harry.
A BALL OF SUNS.
"Hundreds and thousands of stars forming a family party, as it were; and seen from earth they seem to be closely packed together. But if we could draw near to them, however, we should find that they were very far apart. If you look at the Pleiades through your opera glass you will see quite a number of little stars, and if you could see it through the large telescope at the Lick Observatory you would be able to count hundreds of stars. When the cluster had its photograph taken, not long ago, six thousand stars were counted, so you might call the Pleiades a 'ball of suns.' There are hundreds of these clusters, or 'family parties,' in the sky—mighty regiments marching across the star-depths."
"What do you mean, sister?" asked Harry in surprise.
