Letter: That's a great invention you have but we have a problem. Other people have been thinking about the same thing, so you have to make that sewing machine before anyone else will could make it.
Howe is thinking about his invention, and how ha can do it.
I have to do something quick. I'm going to make this so fast that people will be buying sewing machines the next day
It actually took Howe a week to make the invention.
So what does the letter say Howe?
It says that my invention just got patented by the U.S. This is great!
