The four men had risen to their feet. One of them, a well-set-up, handsome young fellow, shook hands with Lavendale.
'I was a year before you at Harvard, wasn't I?' he remarked. 'We think that Mr. Moreton is just a little hard upon us. We represent, to use his own words, the undeniable force, and to do it we have to forget that we are human, and persist. This may be very annoying to Mr. Moreton, but as a rule it is the world that benefits.'
The inventor, who had disappeared for a moment in the interior of the room which led out on to the piazza, suddenly stood upon the threshold. His face seemed to have become graver during the last few moments and he motioned them impatiently back to their places. Then, with a reel of what seemed to be fine wire in his hand, he made his way to the further end of the broad balcony which completely encircled the house, and carefully stretched a length of the wire from the edge of the building to the stone balustrade. As soon as he had accomplished this, he drew from his pockets what appeared to be a pair of black gloves of some spongy material, and a tiny instrument about the size of a lady's watch, which none of them could see. He drew on the gloves with great care, placed the instrument between the palms of his hands and turned to his nephew.
'Just ring the bell there, will you, Jimmy?' he directed.
The young man obeyed. The little group now were all standing up, their eyes fixed upon that strip of thin wire. Mr. Moreton slowly drew his palms together several times, pausing once to glance at the small instrument which lay concealed between them. Footsteps were heard approaching around the side of the house, and a coloured servant in livery, carrying a tray in his hand, appeared. He had no sooner set his foot upon the wire than he stopped short, gave a wild jump into the air, came down again, jumped again, and slowly, with the salver still in his hand, began to dance.
'Touch the bell,' the inventor ordered, in a voice which seemed tense with suppressed emotion.
His nephew obeyed at once and again there were footsteps. Another servant, carrying a chair, came round the corner, paused for a moment as though in amazement on perceiving the antics of his predecessor, stepped on to the wire, leapt into the air, and commenced to perform almost similar gyrations. Mr. Moreton's breath was coming fast and he seemed to be the victim of some peculiar emotion. This time he only glanced towards the bell, which his nephew pushed. Again there were footsteps. A third servant, with a box of cigars, appeared, gave a little exclamation at the extraordinary sight before him, stepped forward on to the wire, leapt up till his head almost touched the sloping portico, and commenced throwing the cigars into the air and catching them. Mr. Moreton glanced from the three performers towards his little audience. The expression on their faces was absolutely indescribable. Meanwhile, the dancing of the three men in livery became more rapid. The man with the salver and glasses began throwing them into the air and catching them again, the servant on the outside was now occupied in balancing a cigar on the tip of his nose, while his neighbour on the right was twirling the wicker chair which he had been carrying, on the point of his forefinger. Mr. Moreton stretched out his hand towards the spellbound, stupefied little company.
