How closely the ground itself may be crowded with plants is seen in Fig. 16, where a young peach orchard, whose tree tops were six feet through, planted in rows twenty-two feet apart, had also ten rows of cabbage, two rows of large windsor beans and a row of garden peas. Thirteen rows of vegetables in 22 feet, all luxuriant and strong, and note the judgment shown in placing the tallest plants, needing the most sun, in the center between the trees. But these old people, used to crowding and to being crowded, and long ago capable of making four blades of grass grow where Nature grew but one, have also learned how to double the acreage where a crop needs more elbow than it does standing room, as seen in Fig. 17. This man's garden had an area of but 63 by 68 feet and two square rods of this was held sacred to the family grave mound, and yet his statement of yields, number of crops and prices made his earning $100 a year on less than one-tenth of an acre. His crop of cucumbers on less than .06 of an acre would bring him $20. He had already sold $5 worth of greens and a second crop would follow the cucumbers. He had just irrigated his garden from an adjoining canal, using a foot-power pump, and stated that until it rained he would repeat the watering once per week. It was his wife who stood in the garden and, although wearing trousers, her dress showed full regard for modesty. But crowding crops more closely in the field not only requires higher feeding to bring greater returns, but also relatively greater care, closer watchfulness in a hundred ways and a patience far beyond American measure; and so, before the crowding of the crops in the field and along with it, there came to these very old farmers a crowding of the grey matter in the brain with the evolution of effective texture. This is shown in his fields which crowd the landscape. It is seen in the crops which crowd his fields. You see it in the old man's face, Fig. 18, standing opposite his compeer, Prince Ching, Fig. 19, each clad in winter dress which is the embodiment of conversation, retaining the fires of the body for its own needs, to release the growth on mountain sides for other uses. And when one realizes how, nearly to the extreme limits, conservation along all important lines is being practiced as an inherited instinct, there need be no surprise when one reflects that the two men, one as feeder and the other as leader, are standing in the fore of a body of four hundred millions of people who have marched as a nation through perhaps forty centuries, and who now, in the light and great promise of unfolding science have their faces set toward a still more hopeful and longer future.
