Long ago, there was a man and woman who lived in a little mud hut under the palm trees on the river bank. They had so many children they did not know what to do. The little hut was altogether too crowded. The man had to work early and late to find food enough to feed so many. One day the seventh son said to his father, “O, father, I found a little puppy yesterday when I was playing on the bank of the river. Please let me bring it home to keep. I have always wanted one.”
The father consented sadly. He did not know how to find food for the children, and an extra puppy to feed seemed an added burden. He went to the river bank to fish that day with a heavy heart. He cast his net in vain. He did not catch a single fish. He cast his net from the other side with no better luck. He did not catch even one little piranha.
Suddenly he heard a voice which seemed to come from the river bed itself, it was so deep. This is what it said: “If you will give me whatever new you find in your house when you go home I will give you fisherman’s luck. You will catch all the fish you wish.”
