“Your father would have understood why I’ve done, what I’m doing; but that’s no reason why the rest of you should. And I rather think it’s the rest of you who’ve suffered most from me. He always knew what I was _there for_, and that must have been some comfort even when I was most in the way; but I was just an ordinary nuisance to you and your mother and Mabel. You were all too kind to let me see it at the time, but I’ve seen it since, and it makes me feel that, after all, the settling of this matter lies with you. If it hurts you to have me go on with my examination of your father’s theory, I’m ready to drop the lectures to-morrow, and trust to the Lanfear Laboratory to breed up a young chap who’ll knock us both out in time. You’ve only got to say the word.” There was a pause while Dredge turned and laid his extinguished pipe carefully between a jar of embryo sea-urchins and a colony of regenerating planarians. Then Archie rose and held out his hand. “No,” he said simply; “go on.” FULL CIRCLE I GEOFFREY BETTON woke rather late--so late that the winter sunlight sliding across his warm red carpet struck his eyes as he turned on the pillow. Strett, the valet, had been in, drawn the bath in the adjoining dressing-room, placed the crystal and silver cigarette-box at his side, put a match to the fire, and thrown open the windows to the bright morning air. It brought in, on the glitter of sun, all the shrill crisp morning noises--those piercing notes of the American thoroughfare that seem to take a sharper vibration from the clearness of the medium through which they pass. Betton raised himself languidly. That was the voice of Fifth Avenue below his windows. He remembered that when he moved into his rooms eighteen months before, the sound had been like music to him: the complex orchestration to which the tune of his new life was set. Now it filled him with horror and weariness, since it had become the symbol of the hurry and noise of that new life. He had been far less hurried in the old days when he had to be up by seven, and down at the office sharp at nine. Now that he got up when he chose, and his life had no fixed framework of duties, the hours hunted him like a pack of blood-hounds.
