The correspondence in this collection is all incoming to Loose and covers the period from 1904 to 1928. The majority of the letters were written by Reed Smoot. Other correspondents include members of the Republican National Committee and Utah Republicans. Many of the issues that Smoot addresses have their joint mining ventures. Smoot's position as chairman of the public lands committee in the Senate seems to have helped Loose at times. Also, the collection contains a report from the Globe Investigation company concerning union organizing that was occurring in the Utah mines. The letters have been placed into chronological order so that the events would unfold as they occurred.
