INTRODUCTION.

THE WRITER INDULGES IN FANCIES.

The summer outing is a fad—a necessity of fashion. Reigning beauty bares its brow on ocean waves and climbs mountain heights, courting sun-kisses. Jaunty sailor hats and narrow visored caps are donned, that the amber burning of the summer's excursion may be displayed at early assemblies of heraldic Four Hundred. Anglo-mania has taught at least one good lesson—that the russet cheek of romping health is more kiss-tempting than the rose-in-cream of beauty lolling on downy cushions. Elite closes its massive doors and draws down front window shades; Paterfamilias sweats in his struggle to force a balance to the credit side, and mothers and daughters sit at back windows in glare of sunlight, wooing sun-beams, while notices of "Out of town" are already placarded on front stoops.

The summer outing is urged by honest doctors, with the admission that change of air and scene is oftentimes worth more than all the nostrums doled out over apothecaries' counters. Motion is nature's first inexorable law. A tiny drop of water is pressed between two plates of glass, apparently rendering the slightest motion impossible. The microscope fills it with scores or hundreds of beings full of life and energy, disporting in pleasure or waging deadly battle. Around us and about us nothing is still. The grasses grow in refreshing green and spring beneath the feet, but ere the wane of day, wither and crackle under the tread. Flowers bloom in beauty and within the hour fade in ugliness. The rock ribs of earth expand and contract under tidal commands of sun and moon, and continents lift from, or are sinking beneath briny oceans.

The gleaming sun, so rounded in glowing calmness as he gently circles across the vaulted sky, is a raging mass of countless millions boiling, dashing, burning jets, in any one of which fiery Vesuvius would be lost as a dim spark. Myriads of starry spheres flecking the midnight sky, are mighty suns tortured by inconceivable convulsions. Far off beyond them the telescopic lens dips up from limitless space countless suns, all boiling, roaring and raging in unending, monstrous motion.
