These three apples on the last of the days of July look fair and sound, partly hidden in the leaves, the deep red colors covering them in broad splashed stripes and relieved by light dots. Yet when I raise the leaves or when I lift the apples apart, I find the burrows of insects. They know that these apples are good. It is astonishing how nature covers up the wounds, how she conceals the sore places, and how fair she makes everything look. Were it not that she covers the depredations of man, the earth would not long remain habitable by him. Summer is ended. Today the sun is on the equator, and we are at the equinox when nights are equal to the days, as the word testifies. The harvest is over. The apples are no more. Yet the tree still is active and preparing for another year (Fig. 12). The spurs are now thick and stout, bearing sturdy hard leaves. The bud in the center is a big one, already recognized as a fruit-bud: here is the promise of speckled, furrowed, striped apples next August. Thereby I learn that it is not enough to be good to the tree in the year in which I desire its fruit: I must begin the year before, and the year before that, and even back at the time when the tree is planted; and if the tree at planting-time is not a good tree, it will be at a disadvantage perhaps all its life long. [Illustration: 12. September 22, and the buds are formed for the next year's crop] Finally the apple is ripe and ready. At the stem end is the "cavity," a depression, deep or shallow, according to variety, in which the stem is set. At the blossom end is the "basin," also with the characteristics of the variety as to depth and width and contour, in which the calyx-lobes persist, and inside the calyx are the remains of the dead stamens and styles; the calyx may be "closed" or "open," the character being a mark of the particular variety. Cut the apple through the center lengthwise (Fig. 13); note the curved outline of the core (the pistil) extending half or more across the fruit; if you do not see this outline, cut an apple until you do; carefully open the five cells or compartments and within the parchment walls find the two seeds attached by their points which are directed toward the stem end; perhaps one of the seeds has failed, but probably a cavity marks its place; perhaps both seeds have failed; perhaps the cell has more than two seeds. [Illustration: 13. The apples in section] Cut an apple cross-wise: note the five radiating cells of the core, the number and attachment of the seeds; note the ten points, imbedded in the flesh, marking the outline of the core. Cut an apple cross-wise above the core and beneath it; note where these points vanish and try to harmonize them with the core-outline as seen in the lengthwise section; probably you will discover why you may not see the core-outline in all the lengthwise sections you make. Before you leave the fruit, note whether single seeds in a cell are the same shape as the two seeds in a cell.
