Farewell, Life! My senses swim,
And the world is growing dim;
Thronging shadows cloud the light,
Like the advent of the night,—
Colder, colder, colder still,
Upward steals a vapor chill—
Strong the earthy odor grows—
I smell the mould above the rose!

Welcome, Life! the Spirit strives!
Strength returns, and hope revives;
Cloudy fears and shapes forlorn
Fly like shadows at the morn,—
O'er the earth there comes a bloom—
Sunny light for sullen gloom,
Warm perfume for vapor cold—
I smell the rose above the mould!

Thomas Hood
