Hushang Teaches Iron and Irrigation

From A2.1, The Rule of Hushang and His Civilizing Arts. It illustrates A2.1.6–10:

A2.1.6
He first drew iron from the hardest stone,And taught the craft that men had never known.
A2.1.7
With growing skill he fashioned tools for toil,The axe, the saw, the mattock for the soil.
A2.1.8
He carved out channels where the streams might run,And watered all the fields beneath the sun.
A2.1.9
Through cut and trench he tamed the water’s pride,And farr made light his labors far and wide.
A2.1.10
As knowledge grew, men learned to sow the grain,Then reaped the harvest yielded by the plain.
