Smoke Test

Famous quotes containing the words smoke and/or test:

“O women, kneeling by your altar-rails long hence,
When songs I wove for my beloved hide the prayer,
And smoke from this dead heart drifts through the violet air
And covers away the smoke of myrrh and frankincense;
Bend down and pray for all that sin I wove in song....”
—William Butler Yeats (1865–1939)
