Their hearts mingled in ardent brotherly affection, the most perfect and heroic affection that can blend men together. And they embraced one another whilst, with her babe on her breast, Marie, so gay, healthful and loyal, looked at them and smiled, with big tears gathering in her eyes.

Thomas, however, having finished his motor's last toilet, had just set it in motion. It was a prodigy of lightness and strength, of no weight whatever in comparison with the power it displayed. And it worked with perfect smoothness, without noise or smell. The whole family was gathered round it in delight, when there came a timely visit, one from the learned and friendly Bertheroy, whom indeed Guillaume had asked to call, in order that he might see the motor working.

The great chemist at once expressed his admiration; and when he had examined the mechanism and understood how the explosive was employed as motive power--an idea which he had long recommended,--he tendered enthusiastic congratulations to Guillaume and Thomas. "You have created a little marvel," said he, "one which may have far-reaching effects both socially and humanly. Yes, yes, pending the invention of the electrical motor which we have not yet arrived at, here is an ideal one, a system of mechanical traction for all sorts of vehicles. Even aerial navigation may now become a possibility, and the problem of force at home is finally solved. And what a grand step! What sudden progress! Distance again diminished, all roads thrown open, and men able to fraternise! This is a great boon, a splendid gift, my good friends, that you are bestowing on the world."

Then he began to jest about the new explosive, whose prodigious power he had divined, and which he now found put to such a beneficent purpose.

"And to think, Guillaume," he said, "that I fancied you acted with so much mysteriousness and hid the formula of your powder from me because you had an idea of blowing up Paris!"

At this Guillaume became grave and somewhat pale. And he confessed the truth. "Well, I did for a moment think of it."

However, Bertheroy went on laughing, as if he regarded this answer as mere repartee, though truth to tell he had felt a slight chill sweep through his hair. "Well, my friend," he said, "you have done far better in offering the world this marvel, which by the way must have been both a difficult and dangerous matter. So here is a powder which was intended to exterminate people, and which in lieu thereof will now increase their comfort and welfare. In the long run things always end well, as I'm quite tired of saying."

On beholding such lofty and tolerant good nature, Guillaume felt moved.

Bertheroy's words were true. What had been intended for purposes of destruction served the cause of progress; the subjugated, domesticated volcano became labour, peace and civilisation. Guillaume had even relinquished all idea of his engine of battle and victory; he had found sufficient satisfaction in this last invention of his, which would relieve men of some measure of weariness, and help to reduce their labour to just so much effort as there must always be. In this he detected some little advance towards Justice; at all events it was all that he himself could contribute to the cause. And when on turning towards the window he caught sight of the basilica of the Sacred Heart, he could not explain what insanity had at one moment cone over him, and set him dreaming of idiotic and useless destruction. Some miasmal gust must have swept by, something born of want that scattered germs of anger and vengeance. But how blind it was to think that destruction and murder could ever bear good fruit, ever sow the soil with plenty and happiness! Violence cannot last, and all it does is to rouse man's feeling of solidarity even among those on whose behalf one kills. The people, the great mult.i.tude, rebel against the isolated individual who seeks to wreak justice. No one man can take upon himself the part of the volcano; this is the whole terrestrial crust, the whole mult.i.tude which internal fire impels to rise and throw up either an Alpine chain or a better and freer society. And whatever heroism there may be in their madness, however great and contagious may be their thirst for martyrdom, murderers are never anything but murderers, whose deeds simply sow the seeds of horror. And if on the one hand Victor Mathis had avenged Salvat, he had also slain him, so universal had been the cry of reprobation roused by the second crime, which was yet more monstrous and more useless than the first.

Guillaume, laughing in his turn, replied to Bertheroy in words which showed how completely he was cured: "You are right," he said, "all ends well since all contributes to truth and justice. Unfortunately, thousands of years are sometimes needed for any progress to be accomplished....

However, for my part, I am simply going to put my new explosive on the market, so that those who secure the necessary authorisation may manufacture it and grow rich. Henceforth it belongs to one and all....

And I've renounced all idea of revolutionising the world."

But Bertheroy protested. This great official scientist, this member of the Inst.i.tute laden with offices and honours, pointed to the little motor, and replied with all the vigour of his seventy years: "But that is revolution, the true, the only revolution. It is with things like that and not with stupid bombs that one revolutionises the world! It is not by destroying, but by creating, that you have just done the work of a revolutionist. And how many times already have I not told you that science alone is the world's revolutionary force, the only force which, far above all paltry political incidents, the vain agitation of despots, priests, sectarians and ambitious people of all kinds, works for the benefit of those who will come after us, and prepares the triumph of truth, justice and peace.... Ah, my dear child, if you wish to overturn the world by striving to set a little more happiness in it, you have only to remain in your laboratory here, for human happiness can spring only from the furnace of the scientist."

He spoke perhaps in a somewhat jesting way, but one could feel that he was convinced of it all, that he held everything excepting science in utter contempt. He had not even shown any surprise when Pierre had cast his ca.s.sock aside; and on finding him there with his wife and child he had not scrupled to show him as much affection as in the past.

Meantime, however, the motor was travelling hither and thither, making no more noise than a bluebottle buzzing in the sunshine. The whole happy family was gathered about it, still laughing with delight at such a victorious achievement. And all at once little Jean, Monsieur Jean, having finished sucking, turned round, displaying his milk-smeared lips, and perceived the machine, the pretty plaything which walked about by itself. At sight of it, his eyes sparkled, dimples appeared on his plump cheeks, and, stretching out his quivering chubby hands, he raised a crow of delight.

Marie, who was quietly fastening her dress, smiled at his glee and brought him nearer, in order that he might have a better view of the toy.

"Ah! my darling, it's pretty, isn't it? It moves and it turns, and it's strong; it's quite alive, you see."

The others, standing around, were much amused by the amazed, enraptured expression of the child, who would have liked to touch the machine, perhaps in the hope of understanding it.

"Yes," resumed Bertheroy, "it's alive and it's powerful like the sun, like that great sun shining yonder over Paris, and ripening men and things. And Paris too is a motor, a boiler in which the future is boiling, while we scientists keep the eternal flame burning underneath.

Guillaume, my good fellow, you are one of the stokers, one of the artisans of the future, with that little marvel of yours, which will still further extend the influence of our great Paris over the whole world."

These words impressed Pierre, and he again thought of a gigantic vat stretching yonder from one horizon to the other, a vat in which the coming century would emerge from an extraordinary mixture of the excellent and the vile. But now, over and above all pa.s.sions, ambitions, stains and waste, he was conscious of the colossal expenditure of labour which marked the life of Paris, of the heroic manual efforts in work-shops and factories, and the splendid striving of the young men of intellect whom he knew to be hard at work, studying in silence, relinquishing none of the conquests of their elders, but glowing with desire to enlarge their domain. And in all this Paris was exalted, together with the future that was being prepared within it, and which would wing its flight over the world bright like the dawn of day. If Rome, now so near its death, had ruled the ancient world, it was Paris that reigned with sovereign sway over the modern era, and had for the time become the great centre of the nations as they were carried on from civilisation to civilisation, in a sunward course from east to west.

Paris was the world's brain. Its past so full of grandeur had prepared it for the part of initiator, civiliser and liberator. Only yesterday it had cast the cry of Liberty among the nations, and to-morrow it would bring them the religion of Science, the new faith awaited by the democracies.

And Paris was also gaiety, kindness and gentleness, pa.s.sion for knowledge and generosity without limit. Among the workmen of its faubourgs and the peasants of its country-sides there were endless reserves of men on whom the future might freely draw. And the century ended with Paris, and the new century would begin and spread with it. All the clamour of its prodigious labour, all the light that came from it as from a beacon overlooking the earth, all the thunder and tempest and triumphant brightness that sprang from its entrails, were pregnant with that final splendour, of which human happiness would be compounded.

Marie raised a light cry of admiration as she pointed towards the city.

"Look! just look!" she exclaimed; "Paris is all golden, covered with a harvest of gold!"

They all re-echoed her admiration, for the effect was really one of extraordinary magnificence. The declining sun was once more veiling the immensity of Paris with golden dust. But this was no longer the city of the sower, a chaos of roofs and edifices suggesting brown land turned up by some huge plough, whilst the sun-rays streamed over it like golden seed, falling upon every side. Nor was it the city whose divisions had one day seemed so plain to Pierre: eastward, the districts of toil, misty with the grey smoke of factories; southward, the districts of study, serene and quiet; westward, the districts of wealth, bright and open; and in the centre the districts of trade, with dark and busy streets. It now seemed as if one and the same crop had sprung up on every side, imparting harmony to everything, and making the entire expanse one sole, boundless field, rich with the same fruitfulness. There was corn, corn everywhere, an infinity of corn, whose golden wave rolled from one end of the horizon to the other. Yes, the declining sun steeped all Paris in equal splendour, and it was truly the crop, the harvest, after the sowing!

"Look! just look," repeated Marie, "there is not a nook without its sheaf; the humblest roofs are fruitful, and every blade is full-eared wherever one may look. It is as if there were now but one and the same soil, reconciled and fraternal. Ah! Jean, my little Jean, look! see how beautiful it is!"

Pierre, who was quivering, had drawn close beside her. And Mere-Grand and Bertheroy smiled upon that promise of a future which they would not see, whilst beside Guillaume, whom the sight filled with emotion, were his three big sons, the three young giants, looking quite grave, they who ever laboured and were ever hopeful. Then Marie, with a fine gesture of enthusiasm, stretched out her arms and raised her child aloft, as if offering it in gift to the huge city.

"See, Jean! see, little one," she cried, "it's you who'll reap it all, who'll store the whole crop in the barn!"

And Paris flared--Paris, which the divine sun had sown with light, and where in glory waved the great future harvest of Truth and of Justice.

THE END
