Give thy thought, O husbandman! to the wild rice; soon nature will give back the rice plump wheat.
Give thyself, O inventor! to the raw ores, and nature will give thee the forceful tools.

Give thyself, O reformer! to the desert world; soon the world-desert will be given back a world-garden.

Give sparingly to nature, and sparingly shalt thou receive again.

Give bountifully, and bounty shall be given back.

Give scant thought and drag but one plank to the stream, and thou shalt receive only a narrow bridge across the brook.
