The present Palace of Justice is for the most part a modern building, but portions of the old edifice of the same name which used to stand upon this spot still remain. In one of these we shall visit the old Conciergerie, which is famous as a French state prison. Here we shall see the little room with a brick floor, in which the beautiful Marie Antoinette, the wife of Louis XVI., was imprisoned for two months before her execution. Here is the very arm-chair in which she sat. Thus we bring to mind the events of the great French revolution, and can easily recall the sorrowful things which took place in the halls and rooms of that gloomy Conciergerie. Another celebrated Parisian church is the Pantheon, an immense edifice. This building was intended as a burial-place for illustrious men of France. We have all heard of the famous cemetery of Pere-Lachaise. It lies within the city, and will be interesting to us, not only because of its great size and beauty, and because it contains the graves of so many persons famous in art, science, literature, and war, but because it is so different from any graveyard to which we are accustomed. It has more than twenty thousand monuments, and many of these are like little houses standing side by side as if they were dwellings on a street. Each vault generally belongs to a family, and the little buildings are almost always decorated with a profusion of flowers and wreaths, and often with pictures and hanging lamps. Here, as in other French cemeteries, it is not uncommon to place a framed photograph of a deceased person over his grave. There are small steamboats which run up and down the Seine like omnibuses, and the charge to passengers is about two cents apiece. These little boats are called by the Parisians _mouches_, or flies, and as they are often very convenient for city trips, we shall take one of them and go to the Jardin des Plantes, a very extensive and famous zooelogical and botanical garden. Here we may ramble for hours, and see animals from all parts of the world in cages, and houses, and in little yards, where they can enjoy the open air. At the other end of the city, outside the walls, is the Jardin d' Acclimatation, that contains a great number of foreign animals and plants, many of which have been naturalized so as to feel at home in the climate of France. In one house here, we may see all kinds of silk-worms, with the plants they feed upon growing near by. In another part of the grounds we shall find trained zebras and ostriches harnessed to little carriages, in which children may take a ride; and we shall see some very gentle elephants and camels, on which we may mount and get an idea of how people travel in the East. We shall here perhaps call to mind the account of this place which was published in ST. NICHOLAS more than ten years ago,--in June, 1874.
