Question

The holiest of all holidays are those

Kept by ourselves in silence and apart;
The secret anniversaries of the heart,
When the full river of feeling overflows;—
The happy days unclouded to their close;
The sudden joys that out of darkness start
As flames from ashes; swift desires that dart
Like swallows singing down each wind that blows!
White as the gleam of a receding sail,
White as a cloud that floats and fades in air,
White as the whitest lily on a stream,
These tender memories are;—a fairy tale
Of some enchanted land we know not where,
But lovely as a landscape in a dream.

Answer 1

White as the gleam of a receding sail,

White as a cloud that floats and fades in air,

White as the whitest lily on a stream,

Step-by-step explanation:

Hyperbole is simply the use of exaggeration for literary effect.

This is a powerful tool that writers often employ to show the extent of something or the effect of that thing on another thing or person.

Therefore, the author compares his memories to the gleam of a receding sail, a cloud and the whitest lily on a stream.
