Retracing our steps a short distance, we continued our ride to Saint Germain en Laye, and observed on our left a stupendous steam engine which, on inquiry, we found is used for supplying the fountains of Versailles and Saint Cloud with water from the Seine, and has succeeded the famous machine of Marly. This machine had become so decayed in some parts before its removal, that it occasioned the death of several persons who were examining its construction--and heedlessly stepped on an old board, which giving way they were precipitated into the river and drowned, or crushed to death by the wheels. Saint Germain en Laye derives its name from the extensive forest adjoining it, which is considered the finest in France, and has ever been the favorite hunting ground of the French monarchs. While partaking of the pleasures of the chase they inhabited the spacious palace, that still exists and is at present a barracks for soldiers. That abject king James the Second, resided in it twelve years, supported by the munificence of Louis le grand, and finally closed his earthly career in this noble retreat. He was buried in the adjoining church, and his heart is enshrined in a paltry looking altar, before which a lamp is constantly burning, and upon which is an inscription informing the reader why it was erected. But what renders the palace at Saint Germain peculiarly interesting, is its having been the residence of the Duchess de la Vallière; and in the ceiling of one of the rooms appropriated to her use there is a trap door, through which it is supposed her enamored sovereign descended when he visited her clandestinely. On the left of the castle is a terrace one mile in length, and bordering an acclivity that overhangs the Seine, and is highly cultivated in vineyards and fruit trees. This terrace is much frequented by persons who resort there, for the purpose of enjoying fresh air and a fine prospect. Some go in carriages, but the usual mode of conveyance is by a donkey, and this we chose. The streets of the town are wide and the houses generally large; which might be expected, as court festivities were so often held here; and now-a-days, many of the Parisian gentry pass the summer months here.
