geological history to the Winnipeg region, and the various for- 

 tunes of the Mississippi, Minnesota and Red rivers ; and through 

 his descriptions Mr. IJpham shows that he has well mastered his 

 subject. His reports also cover the stratigraphical geology of 

 many of the counties. 



The reports by Prof. Winchell bear especially on the Lower 

 Paleozoic and Upper Mesozoic formations; but also on the drift, 

 the drainage, the topography and the economical resources of 

 the State. A highly interesting part relates to the history of the 

 Falls of St. Anthony, in Hennepin Co., which is illustrated by a 

 number of beautiful views and copies of former pictures. The 

 geology of each county is also presented on a finely colored geo- 

 logical map, adding much to the value of the volume. The State 

 is to be congratulated on the successful results of the survey, and 

 the high character of the Reports. 



4. Geological Survey of Kentucky, John R. Procter, Direc- 

 tor. — In the survey of Kentucky under Mr. Procter, several 

 County Reports have been recently issued : on Mason, Bath, 

 Fleming, Henry, Shelby and Oldham Cos., in 1885 to 188V by 

 W. M. Linney; on Elliott Co., by Prof. A. R. Crandall, in 1887, 

 with notes on the Trap dikes by A. R. Crandall and J. S. Diller 

 (see Mr. Diller's paper in this Journ., xxxii, 121, 1886); on the 

 Jackson Purchase Region, or the seven counties lying between 

 the Tennessee River and the Mississippi, by R. H. Loughridge, 

 357 pp. Svo, 1888; and a Chemical Report, by Dr. Robert Peter, 

 containing very many analyses of the coals, soils, clays, petro- 

 leum, mineral waters, etc., 171 pp. 8vo, 1888. Besides colored 

 geological maps of some of the counties in the Reports, a small 

 but handsome State geological map was issued in 1887, by J. B. 

 Hoeing, who is at the head of the Topographical Survey. The 

 Reports treat of the Paleozoic rocks, and chiefly of the coal for- 

 mation of Kentucky ; but also of the soils and other points of 

 economical importance. Mr. Procter's Report of Progress of 1887, 

 states that in addition to the coal beneath the Conglomerate, at 

 the base of the Coal-measures, there are above it, north of Pine 

 Mt., 1650 feet of Coal-measures, containing nine beds of work- 

 able thickness, and between the Pine and Cumberland Mts. a still 

 greater thickness with twelve or more beds. Mr. Loughridge's 

 Report presents evidence from the results of boring a well at 

 Paducah in western Kentucky, on the Ohio, of a fault of 1350 feet. 

 On the Illinois side, the St. Louis limestone of the Subcarbonifer- 

 ous is at the surface, overlying the Keokuk, while on the Ken- 

 tucky side the Keokuk, as the boring shows, is about 1350 feet 

 below the surface, and the overlying rock is the Chester lime- 

 stone, or upper division of the Subcarboniferous. The fault 

 probably extends for some distance southeastward along the east 

 side of the Tennessee River near the junction of the Cretaceous 

 beds of Mississippi valley and the Subcarboniferous.
