NNP Adds San Francisco Mint Notebook
Recently discovered on abebooks.com, by Wayne Homren, is a manuscript notebook of the San Francisco Mint Melter & Refiner, Edwin R. Leach. If the name sounds familiar, Leach was the son of the San Francisco Mint superintendent, Frank A. Leach, who saw the Mint through the 1906 earthquake and fire. The father, Frank A. Leach, later became the overall Mint Director.
The notebook discusses melting and refining processes and apparently represents a trip to the east coast, where Edwin Leach visited a number of smelting facilities. There are still great literature finds to be made “in the wild,” as the discovery of this notebook clearly attests.
