Chapter IV

And now they learn the things they could not know
On mortal earth. They learn the secrets of
All things that are in space above, or in
The Earth beneath: the elements which form
The air that man did breathe, and where obtained,
And how composed. They learn of primal rocks,
Foundations of the new-formed worlds in space,
And how these worlds evolve into abodes
For man. The source of light and heat and power
They find, and grasp the laws by which they may
Be rightly used and perfectly controlled.
And then, most precious gift! they learn of life:
What makes the grass to grow, what gives the flowers
Their fragrance and their many-colored hues.
They comprehend all life in moving forms,--
In worm, in insect, fish, and bird, and beast;
And knowing this, they have the power to draw
Life from its store-house, and to make it serve
The highest good in never-ending ways.
