"At _Taurus_, the wild bull," said Uncle Henry. "You can see that _Taurus_ is very fierce, and would enjoy nothing better than to chase the twin star boys round and round the sky. He might not really want to hurt the boys, whose names are _Castor_ and _Pollux_, but _Taurus'_ horns are very sharp and he doesn't know how to play gently, so it keeps _Orion_ pretty busy getting between him and _Gemini_ and threatening the bull with his club." "What's 'jimini,' Uncle Hen?" said Paul. "Sounds like our swear word." "It _is_ the origin of it," said Uncle Henry. "The ancient Romans used to swear 'by _Gemini_,' and it has slowly been changed into your 'jimini.' _Gemini_ is the Latin word that means 'twins.' We'll find them after we finish up _Orion_ and _Taurus_, and then you'll see just how _Orion_ keeps protecting them from the bull." "Hurry up, Uncle Hen!" urged Peter. "I'm dreadful excited!" Uncle Henry did, and as a result _Orion_ looked like this: [Illustration] "Ooh! he's got a sword, too!" cried Paul, as Uncle Henry added the three tiny stars below _Orion's_ belt, and drew the outline around them. "Why didn't he use the sword on _Taurus_?" asked Peter. "Because he knew _Taurus_ was only playing in his rough way," Uncle Henry replied. "Well, we've heard a lot about that bull," said Betty. "Let's find him right away." Uncle Henry said nothing, but took the chalk from Betty and drew a light line from _Orion's_ right foot to his left shoulder, and continued it upward about the same distance. (20) "There," he said, "that point is just between the bull's horns and over his right eye. The right eye of _Taurus_ is a very bright star called _Aldebaran_. Anybody see it?" "Oh, I do!" said Paul. "What, hasn't _Taurus_ any left eye, Uncle Hen?" "He has," said Uncle Henry, "but he has it closed just now. He's winking it at _Orion_ as much as to say, 'Oh, I act fierce, but I wouldn't hurt those twins after all. I'm just playing.' Go ahead and put in the stars for the bull's head and horns as fast as you find them, youngsters." The children did, and when Uncle Henry had showed them the fore legs and shoulder, which contains the beautiful little group of faint stars called the _Pleiades_, _Taurus_ looked like this: [Illustration] "Now we want the twins!" cried Betty. "All right," said Uncle Henry, "follow a line straight up the bull's left horn and a little more than the length of the horn beyond its tip and you will reach _Castor_, the head of the fainter twin." (21) Peter and Paul began to show great interest, because they were twins themselves. They demanded that each be allowed to select one of the sky children and finish him completely, without Uncle Henry's assistance. [Illustration] Paul, having first choice because he was twenty minutes younger than Peter, selected _Pollux_, and Peter had to be contented with the less bright _Castor_.
