Green changed to white, emerald to opal: nothing was changed   The man let the water trickle gently into his glass, and as the green clouded, a mist fell from his mind   Then he drank opaline      Memories and terrors beset him, the past tore after him like a panther    And through the blackness of the present he saw the luminous tiger eyes of the things to be   But he drank opaline      And that obscure night of the soul, and the valley of humiliation, through which he stumbled, were forgotten   He saw blue vistas of undiscovered countries, high prospects and a quiet, caressing sea   The past shed its perfume over him to-day held his hand as if it were a little child   And to-morrow shone like a white star; nothing was changed   He drank opaline      The man had known the obscure night of the soul, and lay even now in the valley of humiliation;   And the tiger menace of the things to be was red in the skies, ut for a little while he had forgotten   Green changed to white, emerald to opal;   Nothing was changed
