The twenty letterpress volumes of outgoing correspondence (1897-1922) contained in this collection are primarily concerned with the everyday transactions of Brophy's grocery business. In addition, the volumes contain personal letters, including one thanking F. Augustus Heinze for a contribution to the Irish-American League and several dealing with Brophy's efforts to establish a Thomas Meagher Memorial Fund. There are also letters describing conditions in Butte, and others discussing Brophy's mining claims as well as a stock certificate book for the Brophy Grocery.
