Kino, Juana, and Coyotito at home when the scorpion was about to sting Coyotito.
Kino and Juana take Coyotito to the doctor, but they get rejected for any service because they do not have enough money.
Kino searches the water desperately for clams with pearls in them. He discovers an odd looking clam and when he opened it there was a big pearl inside.
By now the whole town knows of Kino and Juana's possession of the pearl. On his way home there were people gathering around admiring the pearl.
The doctor now provides service to Kino and Juana because he heard of how they found the pearl. He comes over their house and claims he is treating Coyotito when he is actually making him worse in order to get more money.
In this scene Kino and Juana are on their way up to town to try and sell the pearl and see how much its worth so they can become extremely wealthy.
