The others are abundant and are sometimes accompanied by the little gold fern, Gymnogramme triangularis, and rarely by the curious little Botrychium simplex, some of them less than an inch high.

The finest of all the rock ferns is Adiantum pedatum, lover of waterfalls and the finest spray-dust.

The homes it loves best are over-leaning, cave-like hollows, beside the larger falls, where it can wet its fingers with their dewy spray.

Many of these moss-lined chambers contain thousands of these delightful ferns, clinging to mossy walls by the slightest hold, reaching out their delicate finger-fronds on dark, shining stalks, sensitive and tremulous, throbbing in unison with every movement and tone of the falling water, moving each division of the frond separately at times, as if fingering the music.
May and June are the main bloom-months of the year.

Both the flowers and falls are then at their best.
