"Dod Grile" (Mr. Bierce) is a personal friend of mine, & I like him exceedingly — but he knows my opinion of the "Nuggets & Dust," & so I do not mind exposing it to you. It is the vilest book that exists in print — or very nearly so. If you keep a "reader," it is charity to believe he never really read that book, but framed his verdict upon hearsay.
Bierce has written some admirable things — fugitive pieces — but none of them are among the "Nuggets." There is humor in Dod Grile, but for every laugh that is in his book there are five blushes, ten shudders and a vomit. The laugh is too expensive.
