 Title:  Nathan Spencer's account of Godfrey, 1809     
 Dates:  1809 
 Abstract:  This volume contains an essay, apparently written by Pennsylvania farmer Nathan Spencer, about Thomas Godfrey. There are also copies of James Logan's correspondence. Some believe Godfrey invented the quadrant, and Spencer's biography argues this point. Spencer also claims to live on the same farm that Godfrey had owned.
