J.H. Collins to James Shackelford, 1885-1890

Collins wrote to Shackelford often to inform him of the operations taking place in Colorado as part of a mining business. He goes into great detail to inform Mr. Shackelford about what kinds of minerals they were excavating as well as the amounts which they found. In some of the letters he provides insight as to the conditions of the workers and explains any problems that he may have been encountering with the employees.
