When the ditch was dug, he wound stout ropes about the mould, and with the aid of windlasses prepared for that purpose, he raised it with every possible precaution, swung it out over the ditch, and let it down slowly until it was on a level with the furnace. He fixed it firmly in place there by piling around it the dirt taken from the ditch, treading it down, and putting in place, as the dirt rose about the mould, the pieces of earthen pipe which were to serve as air-holes. All these preparations took the rest of the day. Night came. For forty-eight hours Benvenuto had not slept nor lain down, nor even sat down. The workmen implored, Scozzone scolded, but Benvenuto would hear none of it: he seemed to be sustained by some more than human power, and made no other reply to the entreaties and scolding than to assign to each workman his task, in the short, stern tone of an officer manœuvring his troops. Benvenuto was determined to begin the casting at once: the energetic artist, who was accustomed to see all obstacles yield before him, exerted his imperious power upon himself; he ordered his body to act, and it obeyed, while his companions were obliged to withdraw, one after another, as in battle wounded soldiers leave the field and seek the hospital. The casting furnace was ready: it was filled with round ingots of brass and copper, symmetrically piled one upon another, so that the heat could pass between them, and the fusion be effected more quickly and more completely. He set fire to the wood around it as in the case of the other furnace, and as it was mostly spruce, the resin which exuded from it, in conjunction with the combustible nature of the wood, soon made such a fierce flame that it rose higher than was anticipated, and lapped the roof of the foundry, which took fire at once, being of wood. At the sight of this conflagration, and more especially at the heat which it gave forth, all the artist's comrades, save Hermann, drew back; but Hermann and Benvenuto were a host in themselves. Each of them seized an axe and cut away at the wooden pillars which upheld the roof, and in an instant it fell in. Thereupon Hermann and Benvenuto with poles pushed the burning fragments into the furnace, and with the increased heat the metal began to melt.
