Running streams and rivers carry seeds uninjured for many miles and finally deposit them in places where they sprout and grow into trees.

Many seeds are carried by the ocean currents to distant foreign shores.
The decay of leaves and woodland vegetation forms rich and fertile soils in the forests, in which conditions are favorable for the development of new tree growth.

When living tree seeds are exposed to proper amounts of moisture, warmth and air in a fertile soil, they will sprout and grow.

A root develops which pushes its way down into the soil, while the leaf-bud of the plant, which springs from the other end of the seed, works its way upward toward the light and air.

This leafy part of the seed finally forms the stem of the tree.
