Series 1: Mining

This series contains records related to the mines near the city of Hamilton in White Pine County, Nevada.

The 262 letters and 1 poem included in this collection were written by Sinclair Lewis to Marcella Powers between 1939 and 1947. Lewis met Powers in August 1939 when they were both acting in Eugene O’Neill’s play Ah Wilderness! at the Provincetown Theater in Cape Cod. Lewis and Powers began a relationship despite the 36 year age difference between them.

In these letters, Lewis discusses a wide variety of topics - his career, his writing, and his feelings for Powers. During the time of their relationship, Lewis traveled quite a bit throughout the United States giving lectures. He also spent time working in Los Angeles in the motion picture industry and lived in Excelsior and Duluth in Minnesota where he spent much time writing. Lewis also wrote about his social life, including the people that he met, the games of chess that he played, and the books that he read. Many of the letters are very long while others are quite short, with some including cartoons drawn by Lewis.

The letters end in September 1947, shortly after Powers marriage to Michael Amrine. Lewis tells Powers that she will no longer receive an allowance from him, but that if she were ever in need of help that he would be there for her. When Lewis passed away in 1951, Powers was listed in his will.
