Sources of Information about Edwin J. Hulbert
Edwards, George, “The Late Edwin J. Hulbert“, Mining and Engineering World, Volume 33, Nov. 26, 1910 p 988. (Page 2 of this post)
“Biography of Edwin James Hulbert (1829-1910)“ in: Hannan, Caryn, Michigan Biographical Dictionary: A-I, (1998) pp 340-342. This book is not in the public domain, but the entry on Hulbert is available online. Not mentioned there is that Hulbert also served as the ‘Vice-President for Houghton County’ of the Pioneer Society of Michigan in the 1870s, which published the annual periodical Historical Collections.
The following book was published in 1893 (actually a collection of several long letters) in which Hulbert described his work and discoveries from 1854 to 1864. Unfortunately it could not be found online.
Hulbert, E. J., Calumet-Conglomerate, Ontonagon Miner Press 1893. 148 p.
Another booklet was published on the same subject in 1899, which was a response by Hulbert to a newspaper article in which it was claimed that his discovery of the Calumet deposit was actually made by someone else. That Hulbert booklet was entitled Calumet Conglomerate Discovery, but also could not be located online.
As the Hannan biography above mentions, Hulbert was employed for a time in producing maps. One was found online:
Booth, John C. and Hulburt, E. J. Geological and Topographical Map of the Mineral District of Lake Superior, Mich., NY: 1864

Hulbert, and a little background on the beginning of mining operations by the Calumet & Hecla company. The book is not in the public domain, but this portion is available online.
