You must have sometimes noted this fact that I am going to remind you of and to use for a special illustration. Riding along over a rocky road, suddenly the slow monotonous grinding of the crushing gravel changes to a deep heavy rumble. There is a great hollow under your feet,--a huge unsunned cavern. Deep, deep beneath you in the core of the living rock, it arches its awful vault, and far away it stretches its winding galleries, their roofs dripping into streams where fishes have been swimming and spawning in the dark until their scales are white as milk and their eyes have withered out, obsolete and useless. So it is in life. We jog quietly along, meeting the same faces, grinding over the same thoughts, the gravel of the soul's highway,--now and then jarred against an obstacle we cannot crush, but must ride over or round as we best may, sometimes bringing short up against a disappointment, but still working along with the creaking and rattling and grating and jerking that belong to the journey of life, even in the smoothest-rolling vehicle. Suddenly we hear the deep underground reverberation that reveals the unsuspected depth of some abyss of thought or passion beneath us. I wish the girl would go. I don't like to look at her so much, and yet I cannot help it. Always that same expression of something that I ought to know,--something that she was made to tell and I to hear,--lying there ready to fall off from her lips, ready to leap out of her eyes and make a saint of me, or a devil or a lunatic, or perhaps a prophet to tell the truth and be hated of men, or a poet whose words shall flash upon the dry stubble-field of worn-out thoughts and burn over an age of lies in an hour of passion. It suddenly occurs to me that I may have put you on the wrong track. The Great Secret that I refer to has nothing to do with the Three Words. Set your mind at ease about that,--there are reasons I could give you which settle all that matter. I don't wonder, however, that you confounded the Great Secret with the Three Words.
