Letting in the Jungle

Veil them, cover them, wall them round--
Blossom, and creeper, and weed--
Let us forget the sight and the sound,
The smell and the touch of the breed!
Fat black ash by the altar-stone,
Here is the white-foot rain
And the does bring forth in the fields unsown,
And none shall affright them again;
And the blind walls crumble, unknown, o'erthrown,
And none shall inhabit again!
