It was my business to cross the bridge, explore the bridge head 3 beyond and find out to what point the enemy had advanced. I did this and returned over the bridge. There were not so many carts now and very few people on foot, but the old man was still there.’’Where do you come from?” I asked him.
“From San Carlos,” he said, and smiled.
That was his native town and so it gave him pleasure to mention it and he smiled.
“I was taking care of animals,” he explained.
“Oh,” I said, not quite understanding.
“Yes,” he said, “I stayed, you see, taking care of animals. I was the last one to leave the town of San Carlos.”
He did not look like a shepherd nor a herdsman and I looked at his black dusty clothes and his gray dusty face and his steel rimmed spectacles and said, “What animals were they?”
“Various animals,” he said, and shook his head. “I had to leave them.”

Then there it lay in her wet palm, perfect, even pierced ready for use, with the sunset shuffled about inside it like gold—?dust. All her heart went up in flames of joy. After a bit she twisted it into the top of her skirt against her tummy so she would know if it burst through the poor cloth and fell. Then she picked up her fork and sickle and the heavy grass and set off home. Ai! Ai! What a day! Her barefeet smudged out the wriggle— ?mark of snakes in the dust; there was the thin singing of malaria mosquitoes among the trees now; and this track was much used at night by a morose old makna elephant—the Tuskless One; but Sibia was not thinking of any of them. The stars came out: she did not notice. On the way back she met her mother, out of breath, come to look for her, and scolding. “I did not see till I was home, that you were not there. I thought something must have happened to you.” And Sibia, bursting with her story, cried “Something did). I found a blue bead for my necklace, look!”
