An old man with steel rimmed spectacles and very dusty clothes sat by the side of the road. There was a pontoon bridge across the river and carts, trucks, and men, women and children were crossing it. The mule-drawn carts staggered up the steep bank from the bridge with soldiers helping push against the spokes of the wheels. The trucks ground up and away heading out of it all and the peasants plodded along in the ankle deep dust. But the old man sat there without moving. He was too tired to go any farther.

Of the seven hundred villages dotting the map of India, in which the majority of India’s five hundred million live, flourish and die, Kritam was probably the tiniest, indicated on the district survey map by a microscopic dot, the map being meant more for the revenue official out to collect tax than for the guidance of the motorist, who in any case could not hope to reach it since it sprawled far from the highway at the end of a rough track furrowed up by the iron-hooped wheels of bullock carts. But its size did not prevent its giving itself the grandiose name Kritam, which meant in Tamil coronet or crown on the brow of the subcontinent. The village consisted of fewer than thirty houses, only one of them built from brick and cement and painted a brilliant yellow and blue all over with

gorgeous carvings of gods and gargoyles on its balustrade, it was known as the Big House. The other houses, distributed in four streets, were generally of bamboo thatch, straw, mud and other unspecified material. Muni’s was the last house in the fourth street, beyond which stretched the fields. In his prosperous days Muni had owned a flock of sheep and goats and sallied forth every morning driving the flock to the highway a couple of miles away.

Its a cruel thing to leave her so.”

“Then take her to the poorhouse: she’ll have to go there,” answered the blacksmith’s wife, springing away, and leaving Joe behind.

For a little while the man stood with a puzzled air; then he turned back, and went into the hovel again. Maggie with painful effort, had raised herself to an upright position and was sitting on the bed, straining her eyes upon the door out of which all had just departed, A vague terror had come into her thin white face.

“O, Mr. Thompson!” she cried out, catching her suspended breath, “don’t leave me here all alone!”           ,

Though rough in exterior, Joe Thompson, the wheelwright, had a heart, and it was very tender in some places. He liked children, and was pleased to have them come to his shop, where sleds and wagons were made or mended for the village lads without a draft on their hoarded sixpences.

“No, dear,” he answered, in a kind voice, going to the bed, and stooping down over the child, “You she’n’t be left here alone.” Then he wrapped her with the gentleness almost of a woman, in the clean bedclothes which some neighbor had brought; and, lifting her in his strong arms, bore her out into the air and across the field that lay between the hovel and his home.

Suddenly all the tension seemed to ebb out of my body as the truth of what he said hit me. Confidently, I drew a line a full foot in back of the board and proceeded to jump from there. I qualified with almost a foot to spare.

That night I walked over to Luz Long’s room in the Olympic village to thank him. I knew that if it hadn’t been for him I probably wouldn’t be jumping in the finals the following day. We sat in his quarters and talked for two hours—about track and field, ourselves, the world situation, a dozen other things.

When I finally got up to leave, we both knew that a real friendship had been formed. Luz would go out to the field the next day trying to beat me if he could. But I knew that he wanted me to do my best—even if that meant my winning.

“Do the scientists really know? Will it happen today, will it ?”
“Look, look; see for yourself !”The children pressed to each other like so many  roses, so many weeds, intermixed, peering out for a look at the hidden sun. It rained. It had been raining for seven years; thousands upon thousands of days compounded and filled from one end to the other with rain, with the drum and gush of water, with the sweet crystal fall of showers and the concussion of storms so heavy they were tidal waves come over the islands. A thousand forests had been crushed under the rain and grown up a thousand times to be crushed again. And this was the way life was forever on the planet Venus, and this was the schoolroom of the children of the rocket men and women who had come to a raining world to set up civilization and live out their lives.
