from 1916 to 1934, the country was divided into 12 senatorial districts. eleven of these districts elected two senators each. in 1916, each district elected two senators (plurality-at-large): one was to serve a six-year term, the other a three-year term. on each election thereafter, one seat per district was up (first past the post). the senators from the 12th district were appointed by the american governor-general for no fixed term.
