Most of the text of “Wie alles begann” (how it began) and “Die goldenen Jahre” (the golden years) is translated from two sources.
History of the Comstock Lode Virginia City, Storey County, Nevada
and “A Kid on the Comstock” by John Taylor Waldorf.
So these sources do not agree completely, there may be something wrong.
