There were also the villages, whose houses, at times, were mere hovels of rubble and boards, some squatting amid muck-heaps, and dingy with woeful want; others more roomy and cheerful, with roofs of pinkish tiles. Strips of garden, victoriously planted amid stony soil, displayed plots of vegetables enclosed by quickset hedges. Much of the aridity of the region had arisen from the ruthless deforesting of the hills; formerly the falling leaves had spread rich vegetable soil over the mountain flanks, there had been good pasture for sheep where barren crags alone were left, and the climate, equalised by the moisture of the woods, had been less abrupt and violent in its changes.[15] Yet, in Zola's youth, as now, "wherever there was the smallest spring, the smallest brook, the glowing land still burst into powerful vegetation, and a dense shade prevailed, with paths lying deep and delightfully cool between plane trees, horse-chestnuts, and elms, all growing vigorously."[16] Those various scenes were a delight to Zola and his friends. "They craved for the open air, the broad sunlight, the sequestered paths in the ravines. They roamed the hills, rested in green nooks, returned home at night through the thick dusk of the highways. In winter they relished the cold, the frosty, gaily echoing ground, the pure sky, and the sharp atmosphere. In summer they always assembled beside the river--the willow-fringed Arc--for the water then became their supreme passion, and they spent whole afternoons bathing, swimming, paddling, and stretching themselves to dry on the fine sun-warmed sand. In the autumn they became sportsmen--inoffensive ones, for there is virtually no game, scarcely even a rabbit, in the district, and at the most one might bring down an occasional petty-chap, fig-pecker, or some other small bird. But if, now and again, they fired a shot, it was chiefly for the pleasure of making a noise, and their expeditions always ended in the shade of a tree, where they lay on their backs, chatting freely of their preferences."[17] A little later, when Zola's young muse essayed her flight, he recalled those days of Provence, singing:
