The garden of the Tuileries is a parallelogram, of, I should think, fifty acres, of which one end is bounded by the palace. It has a high vaulted terrace on the side next the river, as well as at the opposite end, and one a little lower, next the Rue de Rivoli. There is also a very low broad terrace, immediately beneath the windows of the palace, which separates the buildings from the parterres. You will understand that the effect of this arrangement is to shut out the world from the persons in the garden, by means of the terraces, and, indeed, to enable them, by taking refuge in the woods that fill quite half the area, to bury themselves almost in a forest. The public has free access to this place, from an early hour in the morning to eight or nine at night, according to the season. When it is required to clear them, a party of troops marches, by beat of drum, from the chateau, through the great _allee_, to the lower end of the garden. This is always taken as the signal to disperse, and the world begins to go out, at the different gates. It is understood that the place is frequently used as a promenade, by the royal family, after this hour, especially in the fine season; but, as it would be quite easy for any one, evilly disposed, to conceal himself among the trees, statues, and shrubs, the troops are extended in very open order, and march slowly back to the palace, of course driving every one before them. Each gate is locked, as the line passes it. The only parts of the garden, which appear, on the exterior, to be on a level with the street, though such is actually the fact with the whole of the interior, are the great gate opposite the palace, and a side gate near its southern end; the latter being the way by which one passes out, to cross the Pont Royal. In attempting to pass in at this gate the other morning, for the first time, at that hour, I found it closed. A party of ladies and gentlemen were walking on the low terrace, beneath the palace windows, and a hundred people might have been looking at them from without. A second glance showed me, that among some children, were the heir presumptive, and his sister Mademoiselle d'Artois. The exhibition could merely be an attempt to feel the public pulse, for the country-house of La Bagatelle, to which the children go two or three times a week, is much better suited to taking the air. I could not believe in the indifference that was manifested, had I not seen it. The children are both engaging, particularly the daughter, and yet these innocent and perfectly inoffensive beings were evidently regarded more with aversion than with affection.
