I was familiar enough with earthquakes to know that, with the second shock or subsidence of the earth, the immediate danger was passed, and so I was able to note more clearly what else was passing. There was the usual sudden stampede of hurrying feet, the solitary oath and scream, the half-hysterical laughter, and silence. Then the tumult was reawakened to the sound of high voices, talking all together, or the impatient calling of absentees in halls and corridors. Then I heard the quick swish of female skirts on the staircase, and one of the fair guests knocked impatiently at the door of the end room, still immovably fixed. At the first knock there was a sudden cessation of the hurried whisperings and turning of the doorknob. “Mrs. Saltillo, are you there? Are you frightened?” she called. “Mrs. Saltillo”! It was SHE, then, who was in the room! I drew nearer my door, which was still fixed ajar. Presently a voice,--Mrs. Saltillo's voice,--with a constrained laugh in it, came from behind the door: “Not a bit. I'll come down in a minute.” “Do,” persisted the would-be intruder. “It's all over now, but we're all going out into the garden; it's safer.” “All right,” answered Mrs. Saltillo. “Don't wait, dear. I'll follow. Run away, now.” The visitor, who was evidently still nervous, was glad to hurry away, and I heard her retreating step on the staircase. The rattling of the door began again, and at last it seemed to yield to a stronger pull, and opened sufficiently to allow Mrs. Saltillo to squeeze through. I withdrew behind my door. I fancied that it creaked as she passed, as if, noticing it ajar, she had laid an inquiring hand upon it. I waited, but she was not followed by any one. I wondered if I had been mistaken. I was going to the bell-rope to summon assistance to move my own door when a sudden instinct withheld me. If there was any one still in that room, he might come from it just as the servant answered my call, and a public discovery would be unavoidable. I was right. In another instant the figure of a man, whose face I could not discern, slipped out of the room, passed my door, and went stealthily down the staircase.
