Scott: If your typed copy says "Fields" it was certainly not typed by the author, who would not have misspelled his own name. I think we have established that the author was Eugene Field (1850-1895).

Back before photocopiers (Xerox machines, as we called them back then) became common in the 1960s it was not unusual for people to type copies of things they wanted to keep. People even used carbon paper to make multiple copies of things they wanted to distribute to friends. Imagine that!
