They passed the Louvre (lōō´-vr´), once a palace. It is now the largest museum in the world. Here such famous works of art as the Venus de Milo (vē´-nus dĕ mē´-lō) and the Mona Lisa (mō´-nä lē´-zä) are to be seen. [Illustration: THE LOUVRE--THE LARGEST MUSEUM IN THE WORLD] The Arc de Triomphe (ärk dĕ trē´-ônf´) stands as a memorial to the great victories of the French general, Napoleon I. It is an arch of splendor set in the center of branching wide avenues. [Illustration: THE ARC DE TRIOMPHE] For Paris is a city noted for beauty. It was planned and built and dreamed, while most other cities, like Topsy, the colored girl, "just growed." Paris, with its avenues lined with trees, its wide streets and spacious parks, did not "just grow." It was a dream before it was built, and now it is that dream realized. The little girls passed the spot where the Bastille once stood. This was the famous prison into which people were thrown by the French kings, usually without fair trial. But one day the Parisians marched against the Bastille and burned it to the ground. [Illustration: THE SPOT WHERE ONCE STOOD THE BASTILLE] The little girls passed the Tuileries (twēl-rē´), which are fairy-like gardens. They are a children's paradise, and part of the dream that Paris is. [Illustration: THE TUILERIES--FAIRY-LIKE GARDENS AND CHILDREN'S PARADISE] Margot and Jeanne watched the people sitting outside of cafés on the streets. They watched the fashionable strollers along the boulevards. For Paris is well dressed, both inside and out. French cooking is an art, as is everything that these art-loving people attempt. At the end of their happy day the little girls drove to the park. They sat upon a bench beneath shady trees and they watched a Guignol play. They had chatted and laughed and now were the very best of friends. Margot was a happy little girl that day. She had learned from Jeanne how to play. "Sit still, Pierrot," scolded Jeanne softly so that only Margot might hear. "Pierrot, you shall never come again if you do not behave!" continued Jeanne. Margot was laughing, for she could see Pierrot bouncing up and down on the bench. Of course the other children couldn't see it, but Jeanne told Margot about it. So she could see plainly what this naughty puppet was doing. "Oh, dear!" whispered Jeanne to Margot. "He will do something dreadful when Guignol comes on the stage. You know he cannot bear Guignol!" There now was an ugly, red-nosed clown in the play. He had taken Pierrot's place after that day when poor Pierrot had been abandoned. "Here comes Guignol!" exclaimed Margot. Guignol slid upon the stage and fell flop!--on his nose. Guignol began to dance. But again he tripped over his big feet and landed puff!--on his stomach. He stood up, grunting and groaning and puffing, and again he danced.
