JOSIAH EDWARD SPURR
This was a very astute prediction. At the time, the United States gold mining production was second only to South Africa and American currency was based on the gold standard which seemed to all to be permanent. Half a century later, the U. S went off the gold standard.
Josiah Edward Spurr (1870–1950) was an American geologist, explorer, and author. Born in Gloucester, Massachusetts, he was considered something of a failure as a youth, unsuited for the family fishing business, since on a voyage he invariably became seasick. Since he could not be a productive fisherman like his brothers, his parents decided he might as well go to college. After working his way through Harvard, he began his career with the Minnesota Geological Survey, making the first-ever geological map of the great Mesabi iron range in Minnesota.
