Vyatka Governorate
In 1900–1902, Banaitis attended bookkeeping courses in Saint Petersburg. After the graduation, he was offered a government job in the Vyatka Governorate, but refused. Upon return to Lithuania, he spent two years trying to establish a modern dairy. He bought equipment in Warsaw from Jonas Smilgevičius and attempted to produce butter and cheese, but other farmers did not support the effort and the enterprise failed. He attended the Great Seimas of Vilnius in December 1905, but was not very active in its proceedings.
