The Bolls left the commune after the first year and established a farm in Dallas near the current Baylor Medical Center.
In 1878 he collected Permian vertebrate fossils in northwest Texas for Edward Drinker Cope of Philadelphia.
He was a Member of the Boston Society of Natural History and the Academia Caesarea Leopoldino-Carolina Naturae Curiosorum.
