Echo Hill and Mountain Grove continues the story started in The Mill on Halfway Brook, in the Town of Highland, Sullivan County, New York, from 1880 to 1920. It is an account of the change from lumbering, rafting, and bluestone quarrying, to that of running boarding houses in the picturesque hamlets of Barryville, Minisink Ford, Yulan, Eldred, and Venoge located near the Delaware River. It tells the history of the Town of Highland and its townsfolk (Austin, Leavenworth, Eldred, Myers, Bodine, Bradley, Bosch, Clark, Gardner, Hallock, Mills, Boyd, Horton, Parker, Greig, Stege, Sergeant, and Tether), many of whom own boarding houses. Echo Hill and Mountain Grove is bursting with anecdotes and first person accounts about people, boarding houses, occupations, and events. It includes visits to Colorado, Kansas, Nebraska, New York City, and France. The narrative also gives details on the Shohola Depot, Shohola Glen, Shohola House, the Pelton Soda Factory, the Roebling Bridge, the Congregational Church Centennial, Zane Grey, two presidential assassinations, and World War I. Echo Hill and Mountain Grove contains over 900 images (photos, postcards, documents), several first person accounts, an 1881 Diary, 446 letters (150 WWI letters, including some from Lone Scout readers in 1918), 9 original maps, and an index of 1500 people, places, and events. It is the second book in the series, Memoirs from Eldred, New York, 1800 1950.
