There is one marked peculiarity about this paper, a thing nobody seems to notice but myself, and that is that it changes as the light changes.

When the sun shoots in through the east window—I always watch for that first long, straight ray—it changes so quickly that I never can quite believe it.

That is why I watch it always.

By moonlight—the moon shines in all night when there is a moon—I wouldn’t know it was the same paper.

At night in any kind of light, in twilight, candlelight, lamplight, and worst of all by moonlight, it becomes bars! The outside pattern I mean, and the woman behind it is as plain as can be.

I didn’t realize for a long time what the thing was that showed behind,—that dim sub-pattern,—but now I am quite sure it is a woman.

By daylight she is subdued, quiet. I fancy it is the pattern that keeps her so still. It is so puzzling. It keeps me quiet by the hour.
