Capella means "a kid," or "little goat," and that reminds me of the third reason why I enjoy so much the constellation of which Capella is the brightest star. In the old times they sometimes called this five-sided figure "the goat-carrier." And the shepherds thought they could see a man carrying a little goat in his left hand. I am sure you can see the kid they meant. It is a triangle of faint stars which you see near Capella. That's enough for to-night. To-morrow night let us look for Perseus. I dare say you know that old tale about Perseus rescuing the princess who was chained upon a rock. (He cut off the snaky head of Medusa and showed it to the dragon that was going to devour the princess, and it turned the monster to stone. Remember?) Well, there are constellations named after all the people in that story, but although they contain many showy stars, I could never make them look like a hero, a princess, a king, and a queen. I do not even try to trace out all of Perseus. For I am satisfied to enjoy a very beautiful part of it which is called the "Arc of Perseus." An arc, you know, is a portion of a circle. And the way to find this arc is to draw a curve from Capella to Cassiopeia. On nights that are not very clear I can see about seven stars in this Arc of Perseus. And the reason I love it so much is that it is the most beautiful thing, when seen through an opera-glass, that I know. You could never imagine that a mere opera-glass would make such a difference. The moment I put it to my eyes about a dozen more stars suddenly leap into my sight in and near the Arc of Perseus. That's enough. No more stories to-night. WINTER CONSTELLATIONS By winter constellations I mean those you can see in winter at the pleasantest time--the early evening. And I want you to begin with the Northern Cross. I hope you can see this before Christmas, for, after that, it may be hidden by trees or buildings in the west and you may not see it again for a long while. This is because the stars seem to rise in the east and set in the west. To prove this, choose some brilliant star you can see at five or six o'clock; get it in line with some bush or other object over which you can just see it. Put a stake where you stand, and then go to the same spot about eight o'clock or just before you go to bed. You can tell at once how much the star seems to have moved westward. Another thing, every star rises four minutes later every night, and therefore the sky looks a little different at the same hour every evening. The stars in the north set for a short time only, but when those toward the south set they are gone a long time. For instance, the brightest star of all is Sirius, the Dog Star, which really belongs to the southern hemisphere. There are only about three months in the year when children who go to bed by seven o'clock can see it--January, February, and March.
