Laura, Were there significant negative influences on the workers' health when taking on such a project as working in glass for such a long time that working off a land indenture would require or even be possible? Was this Mr. Wistar asking these workers to indenture themselves to him, knowing or thinking they'd die before the land could be claimed, and so he'd benefit from their work and never or almost never need to give them any land?
But of course, this is a part of the story that no one would want out to the public about their business dealings, isn't it. So Wistar would have remained very quiet. Only a reporter or a detective or the police would investigate a situation like this.
And I must submit that I'm a great lover of mystery stories, especially historical ones.
