From my boyhood I have observed leaves, trees, and grass, and I have never found two alike. They may have a general likeness, but on examination I have found they differ slightly. Plants are of different families... it is the same with animals... it is the same with human beings; there is some place which is best adapted to each. The seeds of the plant are blown about by the wind until they reach the place where they will grow best--where the action of the sun and presence of the moisture are most favorable to them, and there they take root and grow.
