It was no mere prettiness of single Trees, but something massed and mountainous. About her rose the wall of its huge opposition to the sky, its scale gigantic, its power utterly prodigious. What she knew of it hitherto as green and delicate forms waving and rustling in the winds was but, as it were the spray of foam that broke into sight upon the nearer edge of viewless depths far, far away. The trees, indeed, were sentinels set visibly about the limits of a camp that itself remained invisible. The awful hum and murmur of the main body in the distance passed into that still room about her with the firelight and hissing kettle. Out yonder—in the Forest further out—the thing that was ever roaring at the center was dreadfully increasing.
