Robert Crawford - Life's Offices.

Most of life's offices may overlap,
And form a covert for the growth of thought;
But there are some no thought and no device
May ever join; or if perchance they do,
Or this or that will soon unsightly warp,
Like green material, and give recourse
To the disastrous airs of circumstance.
