An excerpt from the transcript:
James Rawls, Historian: In Gold Rush California, men from the United States who had lived lives presumably as upright citizens, came to California with great avarice. They were coming here to get rich quick. And they were frustrated men, because they were not getting rich quick, and they’re looking for someone to blame. What is the cause of my own failure?

Narrator: Ever since the first American miners had arrived in California, they had been trying to expel foreigners from the gold fields. But for every one driven out, it seemed, another had come to seek his fortune.
Now, in 1850, there were more than 80,000 Anglo American miners in California, competition was at a fever pitch and anti-foreign sentiment was on the rise.
