His plan to complete his degree was interrupted at the end of the 1907-1908 school year. At that time, the president of BYU, George H. Brimhall, informed him that he had been called to a position as Principal of the Uintah Stake Academy in Vernal, Utah. He spent two years in Vernal and the couple's second child, daughter Lucille, was born there. He then returned to BYU. Manwaring went back to teaching prep classes while he continued his own education, receiving his B.A. degree in 1911. He taught college English classes while he began graduate work. A second son, Eugune, was born during this period.
