Another problem the university faced was related to the language of instruction. Almost the entire faculty consisted of Germans who spoke Russian only with difficulty, if at all. Most lectures were delivered in German, French, and especially Latin, the mastery of which the German professors considered the "goal of the university and basis of all the Sciences." One of the Russian professors, Nikolay Popovsky, was even reprimanded in 1758 for delivering lectures in Russian. In May and June 1767, while traveling with Catherine and her court on the Volga River, Kheraskov appealed directly to Catherine, and in 1768, professors were permitted to speak Russian in the classroom. Catherine considered it especially important that jurisprudence should be taught in Russian. Later in 1767, the Russian edition of the "Encyclopédie" was issued in three parts, for which Kheraskov had translated three articles, "Magic," "Narration," and "Nature." In 1768, Kheraskov introduced the preliminary censorship of public university speeches and lectures after the speeches of Ivan Andreyevich Tretyakov were deemed to contain "dubious and daring expressions." Tretyakov was a graduate of the University of Glasgow, where, along with fellow Moscow University professor Semyon Efimovich Desnitsky, he had studied directly under Adam Smith. His lectures and books were considered to be largely verbatim transcriptions of Smith's lectures, and thus disseminated ideas of the Scottish Enlightenment. In February 1770 Kheraskov traveled to St. Petersburg and in that summer was named the vice president of the Collegium of Mining and promoted to the civil rank of State Councillor. Like in Moscow, his residence in the capital became popular among literary circles. From 1772–1773 he published the journal "Evening", in which the majority of material was published anonymously. Kheraskov also joined the court circle of Grigory Orlov, and maintained friendly relations with him even after Orlov's disgrace. Struggling to balance his civil duties with his literary and theatrical activities, Kheraskov wrote a letter of resignation to Grigory Potemkin, but requested that he keep his salary in order to enter into "...a new kind of service to Her Majesty." However, the request was not granted, and in March 1775 Kheraskov resigned without pension at the rank of State Councillor. Soviet scholar Alexander Zapadov considered the resignation a disgrace; he suggests that the Empress denied his request because of his enthusiasm for Freemasonry.
