Thank you everyone who's provided their insight on the topic. Is Michelle Cotton's thesis readily available through interlibrary procedures? My own exploration on the topic has achieved similar results as those expressed here: Hamilton College's archives hold roughly forty letters from Susy to Louise Brownell. Brownell later married A.P. Saunders, a chemistry professor and dean of Hamilton (the archivist has lead me to believe that is how they acquired the letters). The archive is in the long-term process of digitizing their holdings as we speak. My curiosity concerning the Brownell correspondence involves something that Twain actually published. In his "In Defense of Harriet Shelley" essay (first published in the North American Review of July, August, and September 1894) he twice mentions "girls' colleges of America." In May I received my MA in editorial studies with a critical edition of the two manuscripts that comprise Twain's work. My research has led me to believe that part of Twain's interest in writing the essay was to discount Brownell academically. The evidence pointing towards this conclusion is not circumstantial, but to be fair, Brownell's letters could stamp it certified. In any event, should any specialist of Twain's later writings be interested in my MA, I would be thrilled at further constructive criticism. Thank you! Alex Effgen Boston University
