"Americans began chewing gum long before 1850, scraping resin from spruce trees, removing any bits of bark or insects and chewing the finished product. Commercially-made gum was of limited availability and came in three types--tree resin, pretroleum-based paraffin and chicle-based. This book examines the chewing gum industry in America from 1850 to 1920"--
