The Campbell MSS., consisting of letters and memoranda to and from different members of the Campbell family who were prominent in the Revolution; dealing for the most part with Lord Dunmore's war, the Cherokee wars, the battle of King's Mountain, land speculations, etc. They are in the possession of Mr. Lemuel R. Campbell, who most kindly had copies of all the important ones sent me, at great personal trouble. Some of the Sevier and Jackson papers, the original MS. diaries of Donelson on the famous voyage down the Tennessee and up the Cumberland, and of Benj. Hawkins while surveying the Tennessee boundary, memoranda of Thos. Washington, Overton and Dunham, the earliest files of the Knoxville _Gazette_, from 1791 to 1795, etc. These are all in the library of the Tennessee Historical Society. For original matter connected with Kentucky, I am greatly indebted to Col. Reuben T. Durrett, of Louisville, the founder of the "Filson Club," which has done such admirable historical work of late years. He allowed me to work at my leisure in his library, the most complete in the world on all subjects connected with Kentucky history. Among other matter, he possesses the Shelby MSS., containing a number of letters to and from, and a dictated autobiography of, Isaac Shelby; MS. journals of Rev. James Smith, during two tours in the western country in 1785 and '95; early files of the "Kentucke _Gazette_"; books owned by the early settlers; papers of Boon, and George Rogers Clark; MS. notes on Kentucky by George Bradford, who settled there in 1779; MS. copy of the record book of Col. John Todd, the first governor of the Illinois country after Clark's conquest; the McAfee MSS., consisting of an Account of the First Settlement of Salt River, the Autobiography of Robert McAfee, and a Brief Memorandum of the Civil and Natural History of Kentucky; MS. autobiography of Rev. William Hickman, who visited Kentucky in 1776, etc., etc. I am also under great obligations to Col. John Mason Brown of Louisville, another member of the Filson Club, for assistance rendered me; particularly for having sent me six bound volumes of MSS., containing the correspondence of the Spanish Minister Gardoqui, copied from the Spanish archives. At Lexington I had access to the Breckenridge MSS., through the kindness of Mr. Ethelbert D. Warfield; and to the Clay MSS. through the kindness of Miss Lucretia Hart Clay. I am particularly indebted to Miss Clay for her courtesy in sending me many of the most valuable old Hart and Benton letters, depositions, accounts, and the like. The Blount MSS. were sent to me from California by the Hon. W. D. Stephens of Los Angeles, although I was not personally known to him; an instance of courtesy and generosity, in return for which I could do nothing save express my sincere appreciation and gratitude, which I take this opportunity of publicly repeating.
