This is the first page of a résumé filled out by Schmerling in 1914 when he became a drawing instructor at the Mikhailov Trade School in Tbilisi. Very few of Schmerling's documents have survived, making this résumé a primary source for basic biographical information.
Interestingly, Schmerling indicated that he was Lutheran, but underneath one can see the word "Orthodox" has been erased. See the annotations for a full translation.
