After acting for two years in the troupe, M. went back to Warsaw, where due to illness, he took a break from his stage activities for a year-and-a-half, traveling afterwards across Poland with various provincial troupes. He acted with Julius Adler in Lodz and made a connection later with "Vik't" as an actor and administrative leader.  Afterwards M. settled in Radom, where he became the lessee of the local theatre "Rozmaytoshtsi", wherein he brought in from time to time Yiddish troupes.
