Thus it is with the two great rivals who perform their various feats à l'envi l'un de l'autre on the opposite sides of the Channel. No sooner does one burst out with some new and bright idea which like a newly-kindled torch makes for awhile all other lights look dim, than the other catches it, finds out some ingenious way of making it his own, and then grows as proud and as fond of it as if it had been truly the offspring of his own brain. But in this strife and this stealing neither party has any right to reproach the other, for the exchange is very nearly at par between them. A very few years ago, half a dozen scraping fiddlers, and now and then a screaming "sirène ambulante," furnished all the music of the Champs Elysées; but now there is the prettiest "salon de concert en plein air" imaginable. By the way, I confess that this phrase "salon de concert en plein air" has something rather paradoxical in it: nevertheless, it is perfectly correct; the concerts of the Champs Elysées are decidedly _en plein air_, and yet they are enclosed within what may very fairly be called a salon. The effect of this fanciful arrangement is really very pretty; and if you have managed your echo of this agreeable fantasia as skilfully, an idle London summer evening has gained much. Shall I tell you how it has been done in Paris? In the lower part of the Champs Elysées, a round space is enclosed by a low rail. Within this, to the extent of about fifteen or twenty feet, are ranged sundry circular rows of chairs that are sheltered by a light awning. Within these, a troop of graceful nymphs, formed of white plaster, but which a spectator if he be amiably disposed may take for white marble, stand each one with a lamp upon her head, forming altogether a delicate halo, which, as daylight fades, throws a faint but sufficient degree of illumination upon the company. In the centre of the enclosure rises a stage, covered by a tent-like canopy and brilliant as lamps can make it. Here the band is stationed, which is sufficiently good and sufficiently full to produce a very delightful effect: it must indeed be very villanous music which, listened to while the cool breeze of a summer's evening refreshes the spirit, should not be agreeable. The whole space between the exterior awning and the centre pavilion appropriated to the band is filled with chairs, which, though so very literally en plein air, were all filled with company, and the effect of the whole thing was quite delightful.
