3. The bloom of the apple-tree
It is evident that the last two years were good ones for my apple limb, for the growths were long (19 and 15 inches) and most of the buds produced spurs. The result is evidenced also in the fact that the limb is this year laden with potential bloom. On 1918 the two spurs bear flowers, one of them only a single bloom and the other five blooms. On 1919 twelve of the fourteen spurs are bearing flowers in the following numbers: 5 flowers, 5, 5, 7, 5, 6, 5, 5, 5, 5, 5, 5 = 63 flowers. On 1920 are no spurs bearing flowers, but the terminal bud (as is frequent on vigorous young trees) bears five flowers. Here, therefore, on this yard of three-year-old twig are seventy-four blossoms.
But there will not be seventy-four fruits; some of the flowers are small and weak; others, as the petals fall, show unmistakable signs of failing. A few of them show the plump form of an embryo apple: I think there are a score of such promises. But I know that others will fail later from physiological causes, and others probably from onslaught of insects or disease or from accidents. If six fair fruits mature on a branch like this, the crop will be good; and probably the branch would not have vigor enough to set as many fruit-buds the following year or to bear as many fruits.
It is good to watch the opening of the apple bloom: pink buds swelling and puffing out each day, the woolly stems elongating, the five overlapping incurving petals spreading and growing big, the stamens, about twenty, straightening up and lengthening their filaments that are attached on the flower-rim; the big light yellow anthers shedding pollen; the five green styles in the center. In some flowers the styles do not develop, and we have one reason why many flowers are sterile.
The flower-clusters differ much among themselves, in size of parts, number of flowers, color; on some trees the flowers appear in advance of most of the leafage, but usually they are coincident with the leaves. Sometimes the flower-stems or peduncles are branched, bearing two or three flowers, and in that case there may be a small green leaf or bract where the fork arises. The placing of the petals in the bud at the epoch of expansion may differ in two flowers on the same tree. One petal may stand guard outside the others and free from them, both edges uncovered, while the remaining petals are spiral with one edge under and one edge over; or there may be two guard petals, one on either side; or sometimes all the petals may be spiral, one margin out, one margin in; in some cases all the petals stand free as the flower is expanding, with no margin interlapping. Sometimes one petal is missing, and again the petals may be six.
This infinite variety within the bonds of so great regularity lends a subtle charm to natural objects, that is wholly absent in man's perfected machine-work. Man aims at uniformity, two and two alike; nature aims at endless difference, every object or even every member of an object having its own character. Much of man's energy is expended in trying to overcome the diverseness of nature.
Gradually and slowly the flower balloons enlarge and puff themselves up, the petals standing together at their tips; all the variety is united into a harmony of exuberance, color and form; then one day there is a shower of genial rain, a warm sun, birds in the air, bees released, grasses soft and lush, and behold! the apple-tree is in bloom,—a great heavenly mound of white and pink exhaling a faint delicious breath. Then the pulses stir, the dogs bark at the edges of the wood, the fields call, the scented winds lead on forever.
