"Meet me outside their offices at nine to-morrow morning," said the stranger, "and they'll let you in." III Not only the next morning, but also on hundreds of mornings following, Castro's and de Mattos' doors opened to Antonio. Somewhat straitened financially, Senhor Castro, the only surviving partner, was coquetting with a rich English wine-merchant who wished to acquire a direct interest in an Oporto wine-lodge of repute. The negotiations demanded an exact stock-taking, and to this end Antonio was engaged for three months at a wage of four milreis a week. The hours were long and the work was heavy. Two porters were at his disposal; but Antonio had often to put his own shoulder to the shifting of a cask. As for the brain-work it was harder than the manual. Following Portuguese custom the Castro wines had been reckoned by weight; and it was the young monk's duty to work out difficult sums in weights and measures, transmuting the awkward Portuguese almudes into equally awkward English tuns and hogsheads. On the last day of July, more than four weeks before anybody expected the work to be finished, Antonio placed a neatly-written summary in his employer's hands. Senhor Castro was delighted. Not only was he able to resume his negotiations a month earlier than he had hoped, but his losses during the siege proved to be less than he had feared. Recalling the strenuous Antonio to his private room he renewed his engagement, and entrusted him with important duties far up the Douro, where the Castro vineyards lay. Throughout a torrid August, in a profound gorge where the quivering heat abode like fiery vapors in a crater, Antonio labored on, tightening the lax Castro discipline and overhauling the muddled organization. Before the feast of Saint Michael and All Angels the vintage was over, and an unusual quantity of good wine had been pressed with exceptional care. The monk returned to Oporto in a wine-boat, and his voyage was not without excitements. Here swirling through a deep ravine, there spreading over wide shallows, the Douro kept its navigators ever on the alert. Once, at sunrise, a bark which was outstripping Antonio's came to grief. Two hogsheads of wine smashed like egg-shells against a jagged reef of slate, and the chocolate-colored water was empurpled with the spilt blood of the vine. On reporting himself to Senhor Castro Antonio found his hours shortened, his importance heightened, and his salary raised to twenty-five milreis a month. But he did not abandon his cheap lodging over the cobbler's shop nor did he soften the austerities of his life. By the beginning of October, continued self-denial enabled him to send to the old cura five English pounds in return for the clothes and money which had started the monk on his secular career.
