This satire on the U.S.A.'s myth of being the "Home of the Oppressed,  
where all men are free and equal", is unrelenting in its pursuit of  
justice through exposure. It draws a scathingly shameful portrait of  
how Chinese immigrants were treated in 19th century San Francisco.  
(Introduction by John Greenman)
