The final two charts (#39 & #40) trace the organizational development of the administrative function from its Chief Clerk roots in 1919, and the Ranger, Naturalist, and Historian park related functions from their 1925 base in the Education (Natural History) Branch under Ansel Hall. Perhaps these two depictions show more about the growth of the Service from a simple organization to a complex organization of interdependent, interrelated subsystems of the whole than any of the organizational charts.

If one actually follows the "time line" one can see more about what has philosophically happened within the organization. Such a review may lend credence to the statement "every thing changes, yet nothing is changed." If one follows from 1925 it is possible to watch the ebb and flow of the organization as forestry (ranger activities) and history spin off, go their own way for a period of time, history and natural history combine for another period of time, and see in 1985 that ranger activi ties and interpretation are combined in Visitor Services, and history and museums are separate under their own Associate Director.
