Again: if we do not, like the Roman Augurs, watch and interpret the flight of birds as of good or evil omen, some of them--I mean some of the birds, not of the Augurs--may help us to become, for a while, independent of fate and fortune. Did you ever, for instance, sit at a window on a summer's evening, and take note how a flight of swallows skims the air? They are not very numerous, perhaps; but as they dart to and fro, and cross and recross before you, their number appears indefinite, and the zigzag peculiarity of their movements can only be verified by the closest possible scrutiny. I have satisfied myself that the motion is regular, and that it describes an elongated figure of 8, traced as I am sure you have often traced it upon ice with the outer edge of your skates. Now, though I tell you this on the faith of my own personal observation, you are not bound to accept my word for it. Dream therefore that, while you are blending two ovals into one figure upon the frozen pond, swallows overhead are keeping time to your gyrations. The winter sport and the summer bird may be made to harmonize, as it is only in a dream; and close watching will enable you hereafter to support or disavow my theory. Again: return, if you please, from air to water, for you have by no means exhausted the resources of this latter element, in the way of material for dreams. Are you an angler? Did you never drowse and doze over your rod, when "sitting in a pleasant shade," on a sultry afternoon, not a nibble disturbed the equanimity of your float? The mere thought were suggestive of a nap--suggestive, that is, to the indolently disposed, with whom however you may not be classed, seeing that your mind is in a state of unwholesome excitement, the which it is my business to allay. And so, I pray you, look deeper into this matter; pry down into the blue transparent depths, and mark the fish that swarm about your hook. Is it paste thereon, or a wriggling worm? Never mind; the bait is singularly attractive. To say nothing of the float gently bobbing ever and anon, and of the tell-tale ripples rising to the surface, you can see with your own eyes how victims dally with temptation; how they course to and fro, and round and round; how one eyes the bait, and another smells it, and another mumbles it; how one swims away, and presently returns, and with him his mate in size and colour. Are they over-fed or over-cautious, that they thus play round, but will not gorge? Does one egg on his brother to try the suspicious morsel, hoping himself to profit by his brother's experience? Is there so much resemblance to human foibles discernible down there, among these poor little inhabitants of the waters under the Earth? The question is worth studying out--especially by a sleepless man, who, while contemplating the forms, the motions, the manners, and the minds of fish, may unconsciously swallow the bait that is thus dropped before him.
