More complex, clever, subtle methods of attack transcended those of the mere devourer of leaf-tissue, as radically as an inventor of most intricate instruments differs from the plodding tiller of the soil. In the center of one leaf, less disfigured than some of its fellows, I perceived four tiny ivory spheres, a dozen of which might rest comfortably within the length of an inch. To my eye they looked quite smooth, although a steady oblique gaze revealed hints of concentric lines. Before the times of Leeuwenhoek I should perhaps have been unable to see more than this, although, as a matter of fact, in those happy-go-lucky days my ancestors would doubtless have trounced me soundly for wasting my time on such useless and ungodly things as butterfly eggs. I thought of the coming night when I should sit and strain with all my might, striving, without the use of my powerful stereos, to separate from translucent mist of gases the denser nucleus of the mighty cosmos in Andromeda. And I alternately bemoaned my human limitation of vision, and rejoiced that I could focus clearly, both upon my butterfly eggs a foot away, and upon the spiral nebula swinging through the ether perhaps four hundred and fifty light-years from the earth. I unswung my pocket-lens,--the infant of the microscope,--and my whole being followed my eyes; the trees and sky were eclipsed, and I hovered in mid-air over four glistening Mars-like planets--seamed with radiating canals, half in shadow from the slanting sunlight, and silhouetted against pure emerald. The sculpturing was exquisite. Near the north poles which pointed obliquely in my direction, the lines broke up into beads, and the edges of these were frilled and scalloped; and here again my vision failed and demanded still stronger binoculars. Here was indeed complexity: a butterfly, one of those black beauties, splashed with jasper and beryl, hovering nearby, with taste only for liquid nectar, yet choosing a little weed devoid of flower or fruit on which to deposit her quota of eggs. She neither turned to look at their beauties nor trusted another batch to this plant. Somehow, someway, her caterpillar wormhood had carried, through the mummified chrysalid and the reincarnation of her present form, knowledge of an earlier, infinitely coarser diet. Together with the pure artistic joy which was stirred at the sight of these tiny ornate globes, there was aroused a realization of complexity, of helpless, ignorant achievement; the butterfly blindly pausing in her flower-to-flower fluttering--a pause as momentous to her race as that of the slow daily and monthly progress of the weed's struggle to fruition.
