The price of entrance to all this prettiness is one franc! This, by the bye, is a part of the arrangement which I suspect is not rivalled in England. Neither will you, I believe, soon learn the easy sort of unpremeditated tone in which it is resorted to. It is ten to one, I think, that no one--no ladies at least--will ever go to your al-fresco concert without arranging a party beforehand; and there will be a question of whether it shall be before tea or after tea, in a carriage or on foot, &c. &c. But here it is enjoyed in the very spirit of sans souci:--you take your evening ramble--the lamps sparkle in the distance, or the sound of the instruments reaches your ears, and this is all the preparation required. And then, as you may always be perfectly sure that everybody you know in Paris is occupied as well as yourself in seeking amusement, the chances are greatly in your favour that you will not reach the little bureau at the gate without encountering some friend or friends whom you may induce to _promener_ their idleness the same way. I often marvel, as I look around me in our walks and drives, where all the sorrow and suffering which we know to be the lot of man contrives to hide itself at Paris. Everywhere else you see people looking anxious and busy at least, if not quite woe-begone and utterly miserable: but here the glance of every eye is a gay one; and even though this may perhaps be only worn in the sunshine and put on just as other people put on their hats and bonnets, the effect is delightfully cheering to the spirits of a wandering stranger. It was we, I think, who set the example of an annual public exhibition by an horticultural society. It has been followed here, but not as yet upon the same splendid scale as in London and its neighbourhood. The Orangery of the Louvre is the scene of this display, which is employed for the purpose as soon as the royal trees that pass their winters in it are taken out to the Gardens of the Tuileries. I never on any occasion remember having been exposed to so oppressive a degree of heat as on the morning that we visited this exhibition. The sun shone with intolerable splendour upon the long range of windows, and the place was so full of company, that it was with the greatest difficulty we crept on an inch at a time from one extremity of the hall to the other. Some of the African plants were very fine; but in general the show was certainly not very magnificent. I suspect that the extreme heat of the apartment had considerably destroyed the beauty of some of the more delicate flowering plants, for there were scarcely any of the frail blossoms of our hothouse treasures in perfection. The collection of geraniums was, compared to those I have seen in England, very poor, and so little either of novelty or splendour about them, that I suspect the cultivation of this lovely race, and the production of a new variety in it, is not a matter of so great interest in France as in England.
