This folder contains fourteen letters written by naturalist and family friend John Burroughs to Mina Edison. Although only one of the letters bears a full date, internal evidence indicates that they cover the years 1910-1917. Subjects discussed in the correspondence include birds, health, family members, proposed visits to the various Burroughs and Edison residences, the Edison family trip to Europe in 1911, the major fire at Edison's West Orange factories in 1914, and World War I. The letters all have traces of paste on their back pages, suggesting that they were originally contained in a scrapbook. Courtesy of Thomas Edison National Historical Park.
