This morning arrives a letter from my ancient silver-mining comrade, Calvin H. Higbie, a man whom I have not seen nor had communication with for forty-four years. . . . [Footnote: Roughing It is dedicated to Higbie.] . . . I shall allow myself the privilege of copying his punctuation and his spelling, for to me they are a part of the man.

He makes no apology for them, and no apology is needed.
