I had filled one page of the pocket-book, and had just turned to the next, when I became conscious of a difficulty in fixing my attention on the subject that was before it. I was at once reminded of the similar difficulty which I felt in Shetland, when I had tried vainly to arrange the composition of the letter to my mother which Miss Dunross was to write. By way of completing the parallel, my thoughts wandered now, as they had wandered then, to my latest remembrance of Mrs. Van Brandt. In a minute or two I began to feel once more the strange physical sensations which I had first experienced in the garden at Mr. Dunross's house. The same mysterious trembling shuddered through me from head to foot. I looked about me again, with no distinct consciousness of what the objects were on which my eyes rested. My nerves trembled, on that lovely summer night, as if there had been an electric disturbance in the atmosphere and a storm coming. I laid my pocket-book and pencil on the table, and rose to go out again under the trees. Even the trifling effort to cross the room was an effort made in vain. I stood rooted to the spot, with my face turned toward the moonlight streaming in at the open door. An interval passed, and as I still looked out through the door, I became aware of something moving far down among the trees that fringed the shore of the lake. The first impression produced on me was of two gray shadows winding their way slowly toward me between the trunks of the trees. By fine degrees the shadows assumed a more and more marked outline, until they presented themselves in the likeness of two robed figures, one taller than the other. While they glided nearer and nearer, their gray obscurity of hue melted away. They brightened softly with an inner light of their own as they slowly approached the open space before the door. For the third time I stood in the ghostly presence of Mrs. Van Brandt; and with her, holding her hand, I beheld a second apparition never before revealed to me, the apparition of her child.
