La Pensée russe
Uspensky's book of essays "Living Numbers" (on the life of workers in the society of the rising capitalism) remained unfinished due to problems with censorship. In mid-1888 he traveled to Siberia and returned with "Letters from the Road" series. In Tomsk he met some political prisoners, as well as the writer Nikolai Naumov. In October "Russkaya Mysl" started to publish the "Heavy Sins" (Грехи тяжкие) series. In December "Works by Gleb Uspensky" in two volumes was published by Pavlenkov, with Nikolai Mikhailovsky's foreword, and enjoyed commercial success.
