But see, the mass begins slowly to melt; huge pieces of cannon float on the surface, like boats on water, and then gradually disappear. Presently upon the top of the mass a crust is seen to form, threatening danger to the furnace as well as to the model prepared to receive the fluid bronze. To prevent this crust from forming, six men were employed day and night in stirring the lava-like sea with long poles of iron; retiring, and being replaced by others every now and then; for the scorching heat, in spite of wetted coverings, causes the skin to crack like the dried rind of a tree. Still the caldron was being stirred, still the fire was goaded to new efforts, but the metal was not yet ready to be allowed to flow. Hour after hour went by, the day passed, and night came on. For five days and four nights the fire had been kept up and urged to the utmost intensity, and still no one could tell how long this was yet to last. The men worked on at their tremendous task in silence; the fearful heat was increasing, and as though it would never stop. There was a terrible weight in the burning air, and it pressed upon the breasts of all. There was anxiety in their hearts, though they spoke not, but most of all in his who had directed this bold undertaking. For five days he had not left the spot, but, like a Columbus watching for the hourly-expected land, had awaited the final moment. On the evening of the fifth day exhausted nature demanded repose, and he sat down to sleep. Hardly had he closed his eyes when his wife roused him with the appalling cry, "Awake, awake, the foundry is on fire!" And it was so. Nothing could stand such terrific heat. The rafters of the building began to burn. To quench the fire in the usual way was impossible, for had any cold fluid come in contact with the liquid metal, the consequences would have been frightful: the furnace would have been destroyed, and the 400 cwt. of bronze lost. With wet cloths, therefore, the burning rafters were covered to smother the flames. But the walls were glowing, too; the whole building was now like a vast furnace. Yet still more fuel on the fire!--the heat is not enough; the metal boils not yet! Though the rafters burn, and the walls glow, still feed, and gorge, and goad the fire! At last the moment comes!--the whole mass is boiling! Then the metal-founder of Munich, Miller by name, called to the men who were extinguishing the burning beams, "Let them burn; the metal is ready for the cast!" And it was just midnight, when the whole of the rafters of the interior of the building were in flames, that the plug was knocked in, and the fiery flood rushed out into the mould below.
