The glen path, narrow and rough, went up and down, still following the water.

Hazel and birch, oak and pine, overhung and darkened it.

Bosses of rock thrust themselves forward, patched with lichen and moss, seamed and fringed with fern and heath.

Roots of trees, huge and twisted, spread and clutched like guardian serpents.

In places where rock had fallen the earth seemed to gape.
