"I
cannot make up my mind whether it is a drawback or an advantage to be so
utterly ignorant of mechanics as I am, I know nothing about mechanical
terms and I am afraid I do make it rather difficult for the draughtsmen
to whom I explain my ideas, but in the factories where I am known, they
are exceedingly patient with me because they seem to have a lot of faith
in my inventions." - Beulah Henry
