Spiritually the jugs may be graduated thus: Just below the shoulder of the first bottle, serious and concentrated conversation. Two inches farther down, sweetly sad memory. Three inches more, thoughts of old and satisfactory loves. An inch, thoughts of old and bitter loves. Bottom of the first jug, general and undirected sadness. Shoulder of the second jug, black, unholy despondency. Two fingers down, a song of death or longing. A thumb, every other song each one knows. The graduation stops here, for the trail splits and there is no certainty. From this point on, anything can happen.
