As indicated in the review by eBookAngel, this narrative is overly sensationalized and quite repetitive, being peiced together apparently from successive newspaper items. After reading other accounts of the flood, it appears that much of the account presented in this book is also fictional, being the work of a 'newsman' under pressure to provide copy designed to sell newspapers. In 1889 as now, exciting stories that sell papers was far more important than accuracy
A much more sober account can be found within the pages of "C.B. Clark's Johnstown City Directory 1889," which may be found online at Ancestry.com. U.S. City Directories [database on-line]. Provo, UT, USA: Ancestry.com Operations, Inc., 2010.
