 He collected examples of Lithuanian folklore (about 160 songs collected by him are known), contributed material to the dictionary of Antanas Juška, translated ten poems from various languages (works by Gavrila Derzhavin, Victor Hugo, Mikhail Lermontov, Friedrich Schiller, Alexander Pushkin, Maria Konopnicka), and wrote a couple papers and articles on language matters.There are hints that he was working on a Russian–Polish–Lithuanian dictionary – no manuscript is known though he was well known to collect words.Even as a judge, he would interrupt court proceedings to take notes on a rarer or more interesting word.
