Heat and light during the period of ripening affect the ripening and perfect flavor of fruits. When American fruits are shown in Europe at expositions their bright coloring and flavor are commented on by all visitors. Given varieties color more perfectly and are richer in flavor than when grown in the moister and cooler air of west Europe. In the same way, apples, pears, grapes, and other fruits show higher color, and are better in flavor grown west of the lakes than in the moister and cooler summer air of Michigan or New England. Even the size and shape of apples are modified and changed by either the air or soil of some of the Rocky Mountain districts. The largest specimens of given varieties have been shown from these regions at our expositions, and in some cases the specimens were longer than those grown farther east, and enlarged in all their parts.
