Tints and Autumn Colors.

Everyone has seen and admired the hennHfnl colors of autumn leaves. but "Very few know anything about the why and wherefore. It has been noticed that in two trees of maples, oak or other trees, coloring In 1 autumn, of the same species, one will often take on much brighter color than the other. It should be remembered that, though there must be certain chemical combinations before any color cnfl.be produced, the act of producing is a vital one, and can only operate under vital conditions. If we cut off a branch of any tree in summer time and throw it aside, the leaves turn black or brown, and without any brilliant color; but if the branch be only half broken off or In some way injured the leaves will color, as If the autumn time hail arrived. This shows that coloring is connected with a check to vital power, short of Its total destruction. Hence, in the autumn, the tree with the greater vital power will color less than the other.
