Who Has Seen the Wind?Christina Rossetti

From Westerm Wind to the wind in this poem by Rossetti. These decent lively simple words communicate a sense of the invisible forces that animate the world- forces which we cannot see, but we know must be there.

who has seen the wind?
Neither I nor you:
But when the leaves hang trembling,
The wind is passing thro;

who has seen the wind:
Neither you non I:
But when the trees bow down their heads,
The wind is passing by.
