Eitz Pri was published, featuring essays by Rabbis Salanter and Spektor - including a foreword by the then lesser-known Rabbi Yisroel Meir HaKohen (the "Chafetz Chaim"). In 1880, Finkel left the kollel so he could devote himself to establishing more kollelim throughout Eastern Europe. In 1880, Spektor also left the Kollel, and Salanter's student Yitzchak Blazer became its new head. Under Blazer's direction, the kollel came to be "considered by its contemporaries as a bastion of the Mussar movement," and was attacked by the Mussar movement's opponents. The Kovno Kollel was later transferred to Slabodka, a suburb of Kovno, where Rabbi Shimon Zvi Dubiansky was appointed rosh kollel and served there until the outbreak of World War II.
