The chapters of especial interest to us are “Ausströmen der Yankees,” pp. 237-41; “Einwanderung von 1815 bis 1830,” pp. 253-58; “Die Wohnsitze” (Illinois and Missouri), pp. 337-40. The author cites many authorities, and his book is of very great value in the study of the assimilation of an expatriated people. LOTHROP, J. S. _J. S. Lothrop’s Champaign County (Ill.) Directory for 1870-1, with History of the same, and of each Township therein. Chicago: J. S. Lothrop_, 1871. Tells a great many things—several of which are false—concerning the early period of Illinois history. LUSK, D. W. _Eighty Years of Illinois Politics and Politicians, Anecdotes and Incidents. A succinct History of the State, 1809-1889. 3d ed. Revised and enlarged. Springfield, Ill.: H. W. Rokker_, 1889. 609+109 pp. The 609 pages are political. The 109 pages have a great interest, dealing as they do with the beginnings of Illinois. Secondary sources are largely quoted. Not exact enough for critical work, yet very suggestive. M’AFEE, ROBERT B. _History of the late War in the Western Country, comprising a full Account of all the Transactions in that Quarter, from the Commencement of Hostilities at Tippecanoe, to the Termination of the Contest at New Orleans on the Return of Peace. Lexington, Ky.: Worsley & Smith, 1816._ 8vo. 534 pp. Very rare. In the Chicago Historical Society Library. A valuable book. Describes the attack on Fort Dearborn in 1812. MACKENZIE, E. _An historical, topographical, and descriptive View of the United States of America, and of Upper and Lower Canada ... the present State of Mexico and South America, and also of the native Tribes of the New World. Newcastle-upon-Tyne: Mackenzie & Dent, 1819._ viii. + 432 pp. The four pages devoted to Illinois are interesting and fairly reliable, though scarcely up to date. The author mentions eighteen works used in compiling his book. MCLAUGHLIN, ANDREW C. _Lewis Cass. Boston: Houghton, Mifflin & Co., 1891._ 363 pp. $1.25. Describes the expedition of General Cass to northern Illinois during the Sauk outbreak of 1827. Criticism: _Nation_, LIII., 204.

Chicago: Herbert S. Stone, 1901._ 322 pp. Scholarly and accurate, and rich in citation of sources. Tells of Old Fort Chartres, John Todd’s Record-Book, the march of the Spaniards across Illinois, and the Chicago massacre. —— _March of the Spaniards across Illinois._ (In his _Chapters of Illinois History, Chicago, 1901_; also in _Mag. of Am. Hist._ N. Y., XV., 457-469, 1886.) Refers to a number of sources. The march is that of 1781 against St. Joseph.
