The stream of civilisation flows on like a river, it is rapid in mid- current, slow at the sides, and has its backwaters. At best, civilisation advances by spirals. The native of New Guinea still employs stone tools; whilst an Englishman can get a nest of matches for twopence, an Indian laboriously kindles a fire with a couple of sticks. The prehistoric hunter of Solutré devoured the horse. In the time of Horace so did the Concanni of Spain. In the reign of Hakon, Athelstan's foster son, horseflesh formed the sacrificial meal of the Norseman. At the present day, as Mr. Lloyd George assures us, the haggard, ill-paid German mechanic breaks his long fast on black bread with rare meals of horseflesh. At La Laugerie Basse, on the right bank of the Vézère, is a vast accumulation of fallen rocks, encumbering the ground for at least thirty-five feet in height under the overhanging cornice. The fallen matter consists of the disintegration of the projecting lip. Against the cliff, under the shelter of the rock, as already said, are cottages with lean-to roofs, internally with the back and with at least half the ceiling composed of the rock. In one of these Lartet and Christy began to sink a pit, beside the owner's bed, and the work was carried on to conclusion by the late Dr. Massenat. The well was driven down through successive stages of Man; deposits from the sous dropped and trampled into the earth floor by the children of the cottagers till the virgin soil was reached; and there, lying on his side, with his hands to his head for protection, and with a block of fallen rock crushing his thigh, lay the first prehistoric occupant of this shelter. On the Causse de Larzac is Navacelles, in Gard; you walk over the arid plain with nothing in sight; and all at once are brought to a standstill. You find yourself at the edge of a crater 965 feet deep, the sides in most places precipitous, and the bottom is reached only by a zig-zag path. In the face of one of the cliffs is the grotto of Blandas, that has been occupied since remote ages. A methodical exploration has revealed a spearhead of silex, a bronze axe, bone bracelets, a coin of the Hundred Years' War, and lastly a little pin- cushion of cloth in the shape of a heart, ornamented with metal crosses, the relic of some refugee in the Reign of Terror, hiding to escape the guillotine.
