On another day perhaps you might have chanced to knock at his door when some serious complication had vexed him--a day when the cogs and pulleys upon which he had depended for certain demonstration had become so tangled up in his busy brain that he had thoughts for nothing else. Then, had he pushed pack his green door to receive you, his greeting might have been as cordial and his welcome as hearty, but before long you would have found his eyes gazing into vacancy, or he would have stopped half-way in an answer to your question, his thoughts far away. Had you loved him you would then have closed the green door behind you and left him alone.
Had you remained you would, perhaps, have seen him spring from his seat and pick up from his work-bench some unfinished fragment. This he would have plunged into the smouldering embers of his forge and, entirely forgetful of your presence, would have seized the handle of the bellows, his eyes intent on the blaze, his lips muttering broken sentences. At these moments, as he would peer into the curling smoke, one thin hand upraised, the long calico gown wrinkling about his spare body, the paper cap on his head, he would have looked like some alchemist of old, or weird necromancer weaving a mystic spell. Sometimes, as you watched his face, with the glow of the coals lighting up his earnest eyes, there would have flashed across his troubled features, as heat lightning illumines a cloud, some sudden brightness from within followed by a quick smile of triumph. The rebellious fragment had been mastered. For the hundredth time the great motor was a success!
And yet, had this very pin or crank or cog, on which he had set such store, refused the next hour or day or week to do its work, no trace of his disappointment would have been found in his face or speech. His faith was always supreme; his belief in his ideals unshaken. If the pin or crank would not answer, the lever or pulley would. It was the "adjustment" that was at fault, not the principle.
And so the dear old man would work on, week after week, only to abandon his results again, and with equal cheerfulness and enthusiasm to begin upon another appliance totally unlike any other he had tried before. "It was only a mile-stone," he would say;
"every one that I pass brings me so much nearer the end."
If you had been only a stranger--some savant, for instance, who wanted a problem in mechanics solved, or a professor, blinded by the dazzling light of the almost daily discoveries of the time, in search of mental ammunition to fire back at curious students daily bombarding you with puzzling questions; or had you been a thrifty capitalist, holding back a first payment until an expert like Richard Horn had passed upon the merits of some new labor-saving device of the day; had you been any one of these, and you might very easily have been, for such persons came almost daily to see him, the inventor would not only have listened to your wants, no matter how absorbed he might have been in his own work, but he would not have allowed you to leave him until he was sure that your mind was at rest.
Had you, however, been neither friend nor client, but some unbeliever fresh from the gossip of the Club, where many of the habitues not only laughed at the inventor's predictions for the future, but often lost their tempers in discussing his revolutionary ideas; or had you, in a spirit of temerity, entered his room armed with arguments for his overthrow, nothing that your good-breeding or the lack of it would have permitted you to have said could have ruffled his gentle spirit. With the tact of a man of wide experience among men, he would have turned the talk into another channel--music, perhaps, or some topic of the day--and all with such exquisite grace that you would have forgotten the subject you came to discuss until you found yourself outside the yard and half-way across Kennedy Square before realizing that the inventor had made no reply to your attacks.
But whoever you might have been, whether the friend of years, the anxious client, or the trifling unbeliever, and whatever the purpose of your visit, whether to shake his hand again for the very delight of touching it, to seek advice, or to combat his theories, you would have carried away the impression of a man whose like you had never met before--a man who spoke in a low, gentle voice, and yet, with an authority that compelled attention; enthusiastic over the things he loved, silent over those that pained him; a scholar of wide learning, yet skilled in the use of tools that obeyed him as readily as nimble fingers do a hand; a philosopher eminently sane on most of the accepted theories of the day and yet equally insistent in his support of many of the supposed sophistries and so-called "fanaticisms of the hour"; an old-time aristocrat holding fast to the class distinctions of his ancestors and yet glorying in the dignity of personal labor; a patriot loyal to the traditions of his State and yet so opposed to the bondage of men and women that he had freed his own slaves the day his father's will was read; a cavalier reverencing a woman as sweetheart, wife, and mother, and yet longing for the time to come when she, too, could make a career, then denied her, coequal in its dignity with that of the man beside her.
A composite personality of strange contradictions; of pronounced accomplishments and yet of equally pronounced failures. And yet, withal, a man so gracious in speech, so courtly in bearing, so helpful in counsel, so rational, human, and lovable, that agree with him or not, as you pleased, his vision would have lingered with you for days.
