The farming teacher told the children to spades and hoes from the car and started them on weeding. He told them all about weeds: how hardy they were; how some grew faster than crops and hid the sun from them; how weeds were good hiding places for bad insects; and how weeds could be a nuisance by taking all the nourishment from the soil. He taught them one thing after another. And while he talked, his hands never stopped pulling out weeds. The children did the same. Then the teacher showed them how to hoe; how to make furrows; how to spread fertilizer; and everything else you had to do to grow things in a field, explaining as he demonstrated.

A little snake put its head out and very nearly bit the hand of Ta-chan, one of the older boys, but the farming teacher reassured him, "The snakes here ain't poisonous, and they won't hurt you if you don't hurt them."

Besides, teaching the children how to plant a field, the farming teacher told them interesting things about insects, birds, and butterflies, about the weather, and about all sorts of other things. His strong gnarled hands seemed to attest that everything he told the children, he had found out himself through experience.

The children were dripping with perspiration when they had finally finished planting the field with the teacher's help. Except for a few furrows that were a bit uneven, it was an impeccable field, whichever way you looked at it.

From that day onward, the children held that farmer in high esteem, and whenever they saw him, even at a distance, they would cry, "There's our farming teacher!" Whenever he had any fertilizer left he would bring it over and spread it on the children's field, and their crops grew well. Every day someone would visit the field and report to the head-master and the other children on how it was doing. The children learned to know the wonder and the joy of seeing the seeds they had planted themselves sprout. And whenever two or three of them were gathered together, talk would turn to the progress of their field.

Terrible things were beginning to happen in various parts of the world. But as the children discussed their tiny field -they were still enfolded in the very heart of peace.
