[4] In April 1913 Stover said "I do not believe in the policy that the parks are merely places people to walk through and look at the trees and gaze at the landscape from a distance, nor do I believe that any one should be permitted to destroy anything, but I take the position that certain parks of the asphalt and the lawns should be open most liberally to the young people for amusement, proper athletics, and recreation, under proper circumstances.

[10] Stover spent the rest of his life developing a summer camp at Beacon, New York, operated by the University Settlement House.
