One is constantly reminded of the infinite lavishness and fertility of Nature--inexhaustible abundance amid what seems enormous waste.

And yet when we look into any of her operations that lie within the reach of our minds, we learn that no particle of her material is wasted or worn out.

It is eternally flowing from use to use, beauty to yet higher beauty; and we soon cease to lament waste and death, and rather rejoice and exult in the imperishable, unspendable wealth of the universe, and faithfully watch and wait the reappearance of everything that melts and fades and dies about us, feeling sure that its next appearance will be better and more beautiful than the last.
