When we have paced the length of the beach, it is pleasant, and not unprofitable, to retrace our steps, and recall the whole mood and occupation of the mind during the former passage. Our tracks, being all discernible, will guide us with an observing consciousness through every unconscious wandering of thought and fancy. Here we followed the surf in its reflux, to pick up a shell which the sea seemed loath to relinquish. Here we found a sea-weed, with an immense brown leaf, and trailed it behind us by its long snake-like stalk. Here we seized a live horseshoe by the tail, and counted the many claws of the queer monster. Here we dug into the sand for pebbles, and skipped them upon the surface of the water. Here we wet our feet while examining a jelly-fish, which the waves, having just tossed it up, now sought to snatch away again. Here we trod along the brink of a fresh-water brooklet, which flows across the beach, becoming shallower and more shallow, till at last it sinks into the sand, and perishes in the effort to bear its little tribute to the main. Here some vagary appears to have bewildered us; for our tracks go round and round, and are confusedly intermingled, as if we had found a labyrinth upon the level beach. And here, amid our idle pastime, we sat down upon almost the only stone that breaks the surface of the sand, and were lost in an unlooked-for and overpowering conception of the majesty and awfulness of the great deep. Thus, by tracking our footprints in the sand, we track our own nature in its wayward course, and steal a glance upon it, when it never dreams of being so observed. Such glances always make us wiser.
