America to build railroads"

Some of them stayed and became Americans as did the Irish.

I can't remember the book but there was a part where some Chinese were prepping a rock
face to blow it for a tunnel. Some foreman type was attempting to tell them how to set
the charge and one of the chinese crew said, something to effect we know what we are
doing, the chinese invented gunpowder.

I wish I had a better memory.
