About six miles from Liege, on the road to Spa, most beautifully situate, lies the little warm spring of the above name. The waters are limpid, inodorous, and tasteless. The temperature is 90½° of Fahrenheit. The specific gravity is that of common water. It contains small quantities of carbonic, sulphuric, and muriatic acid, and also some lime. One hundred pints of this spring yielded 240 grains of saline matters—of which 88 were common salt—91 carbonate of lime—14 sulphate of lime—15 muriate of magnesia—12 alumine—and 15 silice. They are, therefore, very analogous to the waters of Pfeffers, Wildbad, and Schlangenbad—and may be used for the same purposes as their more celebrated contemporaries. They may be reached in nine or ten hours from Ostende, by the rail-road. A young lady from England, who bathed in these waters once, and sometimes twice a day, remarked that she always “felt like eel” after leaving them, and throughout the same day. I do not exactly know what the “eel-feel” is, but I can easily believe that it is not precisely that which the eel itself experiences when it changes its mud-bath for the hands of the cook. SPA. “Heureux qui s’ecartant des sentiers d’ici bas, A l’ombre du desert allant cacher ses pas.” Thirty miles South of AIX-LA-CHAPELLE, and twenty-four South-east of Liege, embosomed in a sombre but rather romantic valley of the Ardennes, lies SPA, formerly one of the most aristocratic and celebrated chalybeates of Europe. We proceed from Liege to Spa along the valley of the Vesdre, and a more beautiful drive can hardly be met with. I do not think it inferior to the banks of the Meuse, and it certainly is much more _beautiful_ than many parts of the Rhine. The sides of the valley are clothed with wood, or cultivated carefully, from their very summits, and studded with beautiful villas, cottages, and hamlets, in all directions. At every winding, we see hundreds of men at work, carrying the new rail-road over rivers and through the solid rock. “Cette route charmante decouvre à chaque detour de ravissants vallons qui laissant aperçevoir au loin des maisons de plaisance, de vieux chateaux, et de riants villages. Les cotes escarpées des montagnes qui en dessinent les sinuositées parsemées d’arbres, de rochers, et de precipices.” At the village of Pepinsterre, about sixteen miles from Liege, we quit the Aix-la-Chapelle road, and turn up to the right. The whole way from this to Spa is a constant ascent, the air becoming more bracing, and the scenery more wild, or of the Ardennes-forest character, till we approach the town through a triple avenue, the centre one a pavé, and the side ones for walking or riding. Spa itself lies in a very picturesque dell, the eastern side of which is very abrupt, and covered with wood. The houses are all white and clean, and the locale, altogether, pleased me more than almost any spa I had previously visited.
