(Colorado) The Engineering and Mining Journal, Scientific Publishing Co.
A great find for Colorado. While the volume studies the latest mining developments, in newspaper fashion with many articles, ads and images, for all parts of the US, the focus on the mining activities in Colorado is quite strong. Touching on many areas around Boulder, as well as Georgetown and into Summit County, there are numerous single page maps and prints as well as some larger foldout images. While many of the images pertaining to the West, such as the material related to the Grand Canyon, are typically taken right from government reports, the material for Colorado appears to be fresh and perhaps sourced from different prospectuses, but we don't immediately recognize them.
Condition is very good for this complete volume, with the over 490 pages, only a few old repairs to handful of text pages. The binding is very solid with wear to the leather corners and spine.
