Los Cerrillos Mines and Their Mineral Resources

INTRODUCTION TO THE 2019 REPRINT This book is a facsimile copy of the work in Cerrillos of Jacob Lyman Hayward. It is now in the public domain, having originally been published in 1880 and has been reprinted, also as a facsimile copy on at least one other occasion. Unfortunately, the prior reprint does not include the detailed map that accompanied the original publication, without which the mine claim descriptions have no geographic context. In addition, this copy includes a reproduction of the original book's cover and advertisements pertaining to the Cerrillos Hills are included at the end of the book.Hayward's 1880 published report gives the regulations and by-laws of the newly formed Galisteo and Los Cerrillos Mining District and includes a map showing the boundaries of these two districts, along with the location of the various mining claims he recorded. It became, and remains to this day, the standard reference of the dramatic increase in Cerrillos Hills mining activity during the last quarter of the Nineteenth Century.Jacob Lyman Hayward, also as J. Lyman and Jacob L Hayward (abt. 1852 - 1925) was born in Cambridge, Massachusetts and died at Mount Gilead, North Carolina, his home for many years. The records for his birth date are somewhat ambiguous, with the earliest from an 1855 Massachusetts census as a three year old with his parents. In the 1900 and 1910 US Federal Census he is listed as being born in 1858, however passport, immigration and death records argue for the earlier date. There is also a record indicating his father may have died in 1855.Hayward graduated from the Massachusetts Institute of Technology and would have been about 27 when he first came to New Mexico in 1879, with the last record of him in the State in early 1883.He spent his working career as a civil/mining/mechanical engineer and served for a time as a Deputy US Mineral Surveyor. As part of that job he recorded the developing mining areas in the Cerrillos Hills. How he came to this government position is not known. This did not prevent him from speculating in mines as he also, usually along with others, staked eleven mining claims in 1879/80.In 1889, at the age of 38 he married 17 year old Hattie DeBarry (1872 - 1930). They had four children and lived their lives in Mount Gilead, North Carolina. As something of an inventor, there are four patents recorded in his name. They include in a locking nut to be used for linking railway rails (1878), a mechanism for improving cash railways (A cash railway is a wire systems that carried cash between sales points and the cash office in shops and department stores.), a cotton press (1893), and an amalgamator for extracting gold and silver from pulverized ore (1885/1894.)
