Some things recede beneath the waves, never to be found again. Years ago I heard a short story on The Moth called "1919." Narrated by a Japanese woman, it was the story of a young woman among many young women coming from Japan to America as "picture brides" in cheap steerage 1919, to be wives for male Japanese immigrants in Hawaii and California. The program had been set up by Japanese societies for moral improvement in America, as the men were gambling away their money and visiting prostitutes. In most places, they were not allowed to marry white women.
The radio show announced at the time that the story was part of a book in progress. The author, who had a female relative who had been a picture bride (I don't think her mother - more likely a grandmother or great-aunt), wrote engagingly about the insecurity the girls had felt, how the poorer girls from the provinces were looked down upon by the girls from Tokyo, and those poorer bonded together; and how one of their number who had been married but quickly widowed was constantly asked to explain how they were supposed to behave when it came time for sex, because none of them had the slightest idea. Eyes open, eyes closed? Knees up, knees down?
I have checked in from time to time for the book, as I think my wife would like it, and I was able to at least trace reference to the radio hour story, stretching back into dimmer and dimmer archives. Now, at last, it has vanished with no trace. I imagine I could, with great effort, find some reference to it, and someone, somewhere still has the 15 year old recording, but that is not actually what I wanted. I want the book, and the book has never existed.
