Diaries kept by Charles Andrews Heath from 1880 to 1949, a decade before his death. There are no volumes for 1882, 1888, and 1889. Heath's brief notations record weather conditions, news about and visits with friends and family, and matters regarding the seed business. He also discusses many Chicago related events such as the Haymarket Riot, the World's Columbian Exposition, the World's Parliament of Religions, and the Iroquois Theatre fire, as well as the Galveston flood, politics, and several wars. Many of the diaries contain newspaper clippings, notes, and business cards.
