He knew his deception, but it was better, he thought, to let her live without the knowledge of the utter impossibility of the fulfillment of her hopes, than to tell her the truth, and break her heart. She would outgrow her girlish love, he argued, and time would soften, if not deaden, the sorrow of his continued absence. For a half-hour they talked, they loved, this man of thirty-three and the girl of seventeen. Who can fathom the mysteries of love! Leaving her in sorrow at his coming departure, but hopeful for the future, he moved toward the workshop of Colchis, while a choking sensation surrounded his heart, and tears filled his eyes. Turning the knob of the last door at the end of the hall, Cobb entered, and found his friend moving toward him. The room was lighted by four Edison incandescent lamps, one in each corner, besides an arc light directly over a large and peculiar machine from which sparks were incessantly being emitted. Like all true workers in electricity, Colchis' apartments were a net-work of wires, while the various parts of the house were connected, in one way or another, for quick communication. The answer to the summons which Cobb had made at the door was given by a speaking-tube, while the door itself opened and closed by magnets; thus Colchis was enabled to remain in his room while answering the calls at his door made by the few who had occasion to visit him. "Ah, Junius, my boy, welcome to the shop!" and the old man grasped the latter's hand. "I was expecting you this morning, sure; for it is now over forty-eight hours since you were here. What has kept you away?" "Duty, master; duty." Cobb had early used the term master, in token of the ability of his old but generous friend. "I was engaged the past two nights, and it was impossible for me to get here; but how progresses the work? Are you making a good showing, for you know the time is drawing near when I shall want the full amount." "Yes; there are nearly eight pounds ready for you when you desire to take them." "Good! It is close to the amount, I must say; and the batteries are still at it, I see." "Will you take a look at the work of the day?" "Yes; but yet, master, you know that I do not pretend to pass upon your work. I am too well satisfied that it is being well done." They moved toward the sparkling and crackling instrument near the further corner of the room.
