The black pile of the furnace soon arose before the young man's view. It was of a very ancient pattern, heavy and squat, not more than fifty feet in height. But by degrees various improvements had been added, new organs, as it were, which had ended by forming a little village around it. The running hall, floored with fine sand, looked light and elegant with its iron framework roofed with tiles. Then on the left, inside a large glazed shed, was the blast apparatus with its steam engine; whilst on the right rose the two groups of lofty cylinders, those in which the combustible gases became purified, and those in which they served to warm the blast from the engine, in order that it might reach the furnace burning hot, and in this wise hasten combustion. And there were also a number of water-tanks and a whole system of piping, which kept moisture ever trickling down the sides of the brick walls in order to cool them and diminish the wear and tear of the awful fire raging within. Thus the monster virtually disappeared beneath the intricate medley of its adjuncts, a conglomeration of buildings, a bristling of iron tanks, an entanglement of big metal pipes, the whole forming an extraordinary jumble which, at night-time especially, displayed the most barbarous, fantastic silhouettes. Above, beside the rock one perceived the bridge which brought the trucks laden with ore and fuel to the level of the mouth of the furnace. Below, the kieve reared its black cone, and then from the belly downward a powerful metal armature sustained the brickwork which supported the water conduits and the four twyers. Finally, at the bottom there was but the crucible, with its taphole closed with a bung of refractory clay. But what a gigantic beast the whole made, a beast of disquieting, bewildering shape, which devoured stones and gave out metal in fusion.

Moreover, was there scarcely a sound, scarcely a light. That mighty digestion apparently preferred silence and gloom. One could only hear the faint trickling of the water running down the sides of the bricks, and the ceaseless distant rumbling of the blast apparatus in the engine-shed. And the only lights were those of three or four lanterns gleaming amidst the darkness, which the shadows of the huge buildings rendered the more dense. Moreover, only a few pale figures were seen flitting about, the eight smelters of the night-shift, who wandered hither and thither whilst waiting for the next 'run.' On the platform of the mouth of the furnace up above one could not even discern the men who, silently obeying the signals sent them from below, poured into the furnace the requisite charges of ore and fuel. And there was not a cry, not a flash of light; it was all dim, mute labour, something mighty and savage accomplished in the gloom.

Jordan, however, moved by the bad news given him, had reverted to his dream; and pointing to the pile of buildings, he said to Luc, who had now joined him: 'You see it, my friend; now am I not right in wishing to do away with all that, in wishing to replace such a cumbersome monster, which entails such painful toil, by my battery of electrical furnaces, which would be so clean, so simple, so easily managed? Since the day when the first men dug a hole in the ground to melt ore by mingling it with branches which they set alight, there has really been little change in the methods employed. They are still childish and primitive. Our blast-furnaces are mere adaptations of the prehistoric pits, changed into hollow columns and enlarged according to requirements. And one continues throwing in the ore and the combustible pell mell, and burning them together. One might take such a furnace to be some infernal animal, down whose throat one is for ever pouring food compounded of coal and oxide of iron, which the beast digests amidst a hurricane of fire, and which it gives out down below in the form of fused metal, whilst the gases, the dust, the slag of every kind goes off elsewhere. And observe that the whole operation rests in the slow descent of the digested substances, in total absolute digestion, for the object of all the improvements hitherto effected has been to facilitate it. Formerly there was no blast, no blowing apparatus, and fusion was therefore slower and more defective. Then cold air was employed, and next it was perceived that a better result was obtained by heating the air. At last came the idea of heating that air by borrowing from the furnace itself the gases which had formerly burnt at its mouth in a plume of flames. And in this wise many external organs have been added to our blast-furnaces, but in spite of every improvement, in spite of their huge proportions, they have remained childish, and have even grown more and more delicate, liable to frequent accidents. Ah! you can't imagine the illnesses which fall upon such a monster. There is no puny, sickly little child in the whole world whose daily digestion gives as much anxiety to his parents as a monster like this gives to those in charge of it. Day and night incessantly two shifts, each of six loaders up above and eight smelters down below, with foremen, an engineer, and so forth, are on the spot, busy with the food supplied to the beast, and the output it yields; and at the slightest disturbance, if the metal run out should not be satisfactory, everybody is in a state of alarm. For five years now this furnace has been alight; never for a single minute has the internal fire ceased to perform its work; and it may burn another five years in the same way before it is extinguished to allow of repairs being made. And if those in charge tremble and watch so carefully over the work, it is because there is the everlasting possibility that the fire may go out of itself, through some accident of unforeseen gravity in the monster's bowels. And to go out, to become extinguished, means death. Ah! those little electrical furnaces of mine, which lads might work, they won't disturb anybody's rest at nights, and they will be so healthy, and so active and so docile!'

Luc could not help laughing, amused by the loving passion which entered into Jordan's scientific researches. However, they had now been joined by Morfain and Petit-Da, and the former, under the pale gleam of a lantern, pointed to one of the four pipes which, at a height of nine or ten feet, penetrated the monster's flanks.

'There! it was that twyer which got stopped up, Monsieur Jordan,' he said, 'and unfortunately I had gone home to bed, so that I only noticed what was the matter the next day. As the blast did not penetrate a chill occurred, and a quantity of matter got together and hardened. Nothing more went down, but I only became aware of the trouble at the moment of tapping, on seeing the slag come out in a thick pulp which was already black. And you can understand my fright; for I remembered our misfortune ten years ago, when one had to demolish a part of the furnace after a similar occurrence.'

Never before had Morfain spoken so many words at a stretch. His voice trembled as he recalled the former accident, for no more terrible illness can fall on the monster than one of those chills which solidify the ore and convert it into so much rock. The result is deadly when one is unable to relight the brasier. By degrees the whole mass becomes chilled and adheres to the furnace; and then there is nothing else to be done but to demolish the pile, raze it to the ground, like some old tower chokeful of stones.

'And what did you do?' Jordan inquired.

Morfain did not immediately answer. He had ended by loving that monster whose flow of glowing lava had scorched his face for more than thirty years. It was like a giant, a master, a god of fire which he adored, bending beneath the rude tyranny of the worship that had been forced upon him the moment he reached man's estate as his sole means of procuring daily bread. He scarcely knew how to read, he had not been touched by the new spirit which was abroad, he experienced no feelings of rebellion, but cheerfully accepted his life of hard servitude, vain of his strong arms, his hourly battles with the flames, his fidelity to that crouching colossus over whose digestion he watched without ever a thought of going out on strike. And his barbarous and terrible god had become his passion; his faith in that divinity was instinct with secret tenderness, and he still quivered with anxiety at the thought of the dangerous attack from which he had saved his idol, thanks to extraordinary efforts of devotion.

'What I did!' he at last responded. 'Well, I began by trebling the charges of coal, and then I tried to clear the twyer by working the blast apparatus as I had sometimes seen Monsieur Laroche do. But the attack was already too serious, and we had to disjoint the twyer and attack the stoppage with bars. Ah! it wasn't an easy job, and we lost some of our strength in doing it. All the same, we at last got the air to pass, and I was better pleased when, among the slag this morning, I found some remnants of ore, for I realised that the matter which had set had got broken up again and carried away. Everything is once more well alight now, and we shall be doing good work again. Besides it will soon be easy to see how things are; the next run will tell us.'

Although he was well-nigh exhausted by such a long discourse, he added in a lower voice: 'I really believe, Monsieur Jordan, that I should have gone up above and flung myself into the mouth if I had not had better news to give you this evening. I'm only a workman, a smelter, in whom you've had confidence, giving me a gentleman's post, an engineer's post. And just fancy me letting the furnace go out and telling you on your return home that it was dead! Ah! no, indeed, I'd have died too! I haven't been to bed for two nights now; I've kept watch here, like I did beside my poor wife when I lost her. And at present, I may admit it, the soup which you found me eating was the first food I had tasted for forty-eight hours, for I couldn't eat before, my own stomach seemed to be stopped up like the furnace's. I don't want to apologise, but simply to let you know how happy I feel at not having failed in the confidence you put in me.'
