And wondrous in melody and restraint of expression is a verse like this:—

"One word is too often profaned
For me to profane it;
One feeling too falsely disdained
For thee to disdain it;
One hope is too like despair
For prudence to smother;
And pity from thee more dear
Than that from another."

The words are few, and there is nothing remarkable in the rhythm, yet there is not a line that could have come from any pen but Shelley's.

In these short poems we are clearly conscious of the poet's melancholy, a melancholy which in his longer works is veiled, or else overpowered by his belief in a bright future, his faith in the progress of the human race. The inmost recesses of his own being were penetrated by a sadness produced by the feeling of the mutability of everything, and by early experience of the manner in which feeling leads astray, love disappoints, and life deceives.

He has given imperishable expression to the feeling of mutability:—

"The flower that smiles to-day
To-morrow dies:
All that we wish to stay
Tempts and then flies.
What is this world's delight?
Lightning that mocks the night.
Brief even as bright.
Virtue, how frail it is!
Friendship how rare!
Love, how it sells poor bliss
For proud despair!
But we, though soon they fall,
Survive their joy, and all
Which ours we call.
Whilst skies are blue and bright,
Whilst flowers are gay,
Whilst eyes that change ere night
Make glad the day,
Whilst yet the calm hours creep,
Dream thou—and from thy sleep
Then wake to weep."

The first verse indicates the transitoriness of all earthly beauty and happiness; the second, the suffering that lies concealed in the very happiness; and the third is an exhortation to enjoy the dream of happiness as long as possible.

A mood of like nature has found expression in the incomparable poem which bears the simple title, Lines. This poem Shelley could not have written unless one after another of his own fond beliefs had evaporated, unless his passions for Harriet, for Mary, for Emilia Viviani, had ended in a sorrowful awakening. Yet it bears no trace of being a personal confession. It is an impassioned proclamation of the universal laws of life, first softly hummed, and then sung in a voice which has never had its equal.

"When the lamp is shattered,
The light in the dust lies dead;
When the cloud is scattered,
The rainbow's glory is shed;
When the lute is broken,
Sweet notes are remembered not;
When the lips have spoken,
Loved accents are soon forgot."

The lines on the human heart in the third verse are as condensed as a couplet of Pope's and as melodious as bars of Beethoven:—
