Duncan Camp is only referred to once in the April, 1925 edition of the Green Mountain News (“Long Trail News”)

“The Duncan Camp of Boy Building has a camp in Peru, not far from the LT, and extends a cordial invitation to hikers over the trail to visit the camp and enjoy its hospitality. ”

This refers to the “Duncan Grant Camp” or “Duncan Camp for Boy Building”, a model airplane summer camp for boys. The camp was founded by Charles Hampson Grant, who named it after his younger brother Duncan, after he died flying a Sopwith Camel in World War I.
