In other parts of the city of Paris, there are street railways, called here tramways, which are managed very much in the same manner as the omnibuses. These vehicles are convenient and cheap, but not very agreeable, and it is much pleasanter to walk and pay nothing, or to take a _voiture_ and pay thirty cents for two people for a drive from one end of the city to another. And thus we go on along the boulevards, passing the celebrated gateways, Porte St. Martin and Porte St. Denis, until we come to the great open space once occupied by the Bastille, in which now rises a tall, sculptured column surmounted by a figure of Liberty. Those who have studied and remembered modern French history will take a great interest in this spot, where so many important events occurred. Here end the boulevards. We now turn toward the river, and soon reach a wide street called the Rue de Rivoli, one side of which is lined with shops under arcades, which, in some respects, are more attractive than any we have yet seen. At many of these, photographs are sold; and their windows are crowded with pictures. All sorts of useful and cheap things are to be found here, and a walk through this street is like a visit to a museum. On the other side of the street is the great Palace of the Louvre, which extends for some distance, and after that, we come to the Garden of the Tuileries. When we have walked through this magnificent pleasure-ground, we shall reach the point from which we started on our tour. [Illustration: THE OPERA-HOUSE, PARIS.] We shall take many other walks and drives through the streets of Paris, and wherever we go, we shall find in each an interest of a different sort. On the southern side of the river, is the Latin Quarter, where there are some celebrated schools and academies, which, for centuries, have been the resort of students. Here we shall find narrow streets, crowded footways, and shops full of all sorts of antiquarian articles, and odds and ends of every kind, some of which seem to have no other value than that they are old, while other things are very valuable, and often very cheap. Here, too, we find book shops, and shops where prints and engravings are sold, and all with their windows and even their outside walls crowded with the best things they have to offer. Along the river front are rows of stalls covered with second-hand books at very low prices, and those of us who are collectors of old coins can find them here by the peck or bushel. In this quarter, also, are some immense dry-goods and variety stores, which are worth going to see. One of them is so large, and there is so much to see in it, that, at three o'clock every day, a guide who can speak English sets out to conduct visitors through the establishment and to explain its various details.
