Still, the effect of the uncovered bed of the Loire, with its variegated pebbles and mirror-like pools, is infinitely more picturesque than if it were mud flats, and its tree-bordered banks are for ever opening great alleyed vistas such as are only known in France. The hills on either bank are not of the stupendous and magnificently scenic order of those of the Seine above and below Rouen; but, such as they are, they are of much the same composition, a soft talcy formation which here serves admirably the purposes of cliff-dwellings for the vineyard and wine-press workers, who form practically the sole population of the Loire villages from Vouvray, just above Tours, to Saumur far below. On the hillsides are the vineyards themselves, growing out of the thin layer of soil in shades of red and brown and golden, which no artist has ever been able to copy, for no one has painted the rich colouring of a vineyard in a manner at all approaching the original. Not far below Tours, on the right bank, rise the towers and turrets of the Château de Luynes, hanging perilously high above the lowland which borders upon the river. An unpleasant tooting tram gives communication a dozen times a day with Tours, but few, apparently, patronize it except peasants with market-baskets, and vineyard workers going into town for a jollification. It is perhaps just as well, for the fine little town of Luynes, which takes its name from the château which has been the residence of a Comte de Luynes since the days of Louis XIII., would be quite spoiled if it were on the beaten track. [Illustration: A VINEYARD OF VOUVRAY] The brusque façade of the Château de Luynes makes a charming interior, judging from the descriptions and drawings which are to be met with in an elaborately prepared volume devoted to its history. The stranger is allowed to enter within the gates of the courtyard, beneath the grim coiffed towers; but he may visit only certain apartments. He will, however, see enough to indicate that the edifice was something more than a mere _maison de campagne_. All the attributes of an important fortress are here, great, round, thickly built towers, with but few exterior windows, and those high up from the ground. There is nothing of luxurious elegance about it, and its aspect is forbidding, though imposing. The château belies its looks somewhat, for it was built only in the fifteenth and sixteenth centuries, when, in most of its neighbours, the more or less florid Renaissance was in vogue. A Renaissance structure in stone and brick forms a part of that which faces on the interior court, and is flanked by a fine octagonal "_tour d'escalier_." From the terrace of the courtyard one gets an impressive view of the Loire, which glides by two or more kilometres away, and of the towers and roof-tops of Tours, and the vine-carpeted hills which stretch away along the river's bank in either direction.
