I Wonder How Many Of Us Could Use Some Silence?

As Discovered by Lewis Francis Hadley in the 1890s,
Quaker, Hadley whose wish to see the Native Americans 
converted to Chrstianity was fairly obvious in his choice
of texts for which he found the Native sign language.

rubbed off on him, there is no further record
of Hadley undertaking the work of an evangelist
after completing his work of translating their sign lannguage.
