"Jars full of water for the journey," answered the merchant.
The demon said, "You have done well to bring water as far as this, but there is no need of it beyond. Empty out all that water and go on easily." Then he added, "But we have delayed too long. Drive on!" And he drove on until he was out of sight of the merchant. Then he returned to his home with his followers to wait for the night to come.
The foolish merchant did as the demon bade him and emptied every jar, saving not even a cupful. On and on they traveled and the streak on the sky faded with the sunset. There was no forest, the dark line being only clouds. No water was to be found. The men had no water to drink and no food to eat, for they had no water in which to cook their rice, so they went thirsty and supperless to bed. The oxen, too, were hungry and thirsty and dropped down to sleep here and there. Late at night the demons fell upon them and easily carried off every man. They drove the oxen on ahead of them, but the loaded carts they did not care to take away.
A month and a half after this the wise merchant followed over the same road. He, too, was met on the desert by the demon just as the other had been. But the wise man knew the man was a demon because he cast no shadow. When the demon told him of the ponds in the forest ahead and advised him to throw away the water-jars the wise merchant replied, "We don't throw away the water we have until we get to a place where we see there is more."
Then the demon drove on. But the men who were with the merchant said, "Sir! those men told us that yonder was the beginning of a great forest, and from there onwards it was always raining. Their clothes and hair were dripping with water. Let us throw away the water-jars and go on faster with lighter carts!"
Stopping all the carts the wise merchant asked the men, "Have you ever heard any one say that there was a lake or pond in this desert? You have lived near here always."
"We never heard of a pond or lake," they said.
"Does any man feel a wind laden with dampness blowing against him?" he asked.
"No, sir," they answered.
"Can you see a rain cloud, any of you?" said he.
