So long as the thing a man works with is a part of an inner ideal to him, so long as he makes the thing he works with express that ideal, the heat and the glow and the lustre and the beauty and the unconquerableness of that man, and of that man’s delight, shall be upon all that he does. It shall sing to heaven. It shall sing to all on earth who overhear heaven.

Every man who loves his work, who gets his work and his ideal connected, who makes his work speak out the heart of him, is a poet. It makes little difference what he says about it. In proportion as he has power with a thing; in proportion as he makes the thing—be it a bit of color, or a fragment of flying sound, or a word, or a wheel, or a throttle—in proportion as he makes the thing fulfill or express what he wants it to fulfill or express, he is a poet. All heaven and earth cannot make him otherwise.

That the inventor is in all essential respects a poet toward the machine that he has made, it would be hard to deny. That, with all the apparent prose that piles itself about his machine, the machine is in all essential respects a poem to him, who can question? Who has ever known an inventor, a man with a passion in his hands, without feeling toward him as he feels toward a poet? Is it nothing to us to know that men are living now under the same sky with us, hundreds of them (their faces haunt us on the street), who would all but die, who are all but dying now, this very moment, to make a machine live,—martyrs of valves and wheels and of rivets and retorts, sleepless, tireless, unconquerable men?

To know an inventor the moment of his triumph,—the moment when, working his will before him, the machine at last, resistless, silent, massive pantomime of a life, offers itself to the gaze of men’s souls and the needs of their bodies,—to know an inventor at all is to know that at a moment like this a chord is touched in him strange and deep, soft as from out of all eternity. The melody that Homer knew, and that Dante knew, is his also, with the grime upon his hands, standing and watching it there. It is the same song that from pride to pride and joy to joy has been singing through the hearts of The Men Who Make, from the beginning of the world. The thing that was not, that now is, after all the praying with his hands … iron and wood and rivet and cog and wheel—is it not more than these to him standing before it there? It is the face of matter—who does not know it?—answering the face of the man, whispering to him out of the dust of the earth.

What is true of the men who make the machines is equally true of the men who live with them. The brakeman and the locomotive engineer and the mechanical engineer and the sailor all have the same spirit. Their days are invested with the same dignity and aspiration, the same unwonted enthusiasm, and self-forgetfulness in the work itself. They begin their lives as boys dreaming of the track, or of cogs and wheels, or of great waters.

As I stood by the track the other night, Michael the switchman was holding the road for the nine o’clock freight, with his faded flag, and his grim brown pipe, and his wooden leg. As it rumbled by him, headlight, clatter, and smoke, and whirl, and halo of the steam, every brakeman backing to the wind, lying on the air, at the jolt of the switch, started, as at some greeting out of the dark, and turned and gave the sign to Michael. All of the brakemen gave it. Then we watched them, Michael and I, out of the roar and the hiss of their splendid cloud, their flickering, swaying bodies against the sky, flying out to the Night, until there was nothing but a dull red murmur and the falling of smoke.

Michael hobbled back to his mansion by the rails. He put up the foot that was left from the wreck, and puffed and puffed. He had been a brakeman himself.

Brakemen are prosaic men enough, no doubt, in the ordinary sense, but they love a railroad as Shakespeare loved a sonnet. It is not given to brakemen, as it is to poets, to show to the world as it passes by that their ideals are beautiful. They give their lives for them,—hundreds of lives a year. These lives may be sordid lives looked at from the outside, but mystery, danger, surprise, dark cities, and glistening lights, roar, dust, and water, and death, and life,—these play their endless spell upon them. They love the shining of the track. It is wrought into the very fibre of their being.

Years pass and years, and still more years. Who shall persuade the brakemen to leave the track? They never leave it. I shall always see them—on their flying footboards beneath the sky—swaying and rocking—still swaying and rocking—to Eternity.

They are men who live down through to the spirit and the poetry of their calling. It is the poetry of the calling that keeps them there.
