gerated in the past; that its transporting power has not been clearly 
discriminated from its eroding power; that it probably did not make 
rock basins, much less valleys; that in general its effect was to cut 
down prominences and fill depressions, and thus to lessen rather than 
to strengthen relief. He regards the drift as largely composed of 
material furnished by preglacial decay of northern rock. With this 
was mingled such fresh material as the ice could break from projecting 
points, and tear or wear from its bed. 
Crystalline Limestones, Ophicalcites and Associated Schists of the Eastern 
Adtrondacks. By J. ¥. Kemp. Bull. Geol. Soc. of Amer., VI., 
241-262, 1895. 
As study of the crystalline rocks in the eastern Adirondacks has 
progressed, it has become evident that in the gneissoid rocks on all 
sides of the Norian intrusions of anorthosites and gabbros, and 
extending well up between their ridges, crystalline, graphitic lime- 
stones, ophicalcites, and associated black hornblendic schists are met. 
Interlaminated with these are feldspathic gneisses, and occasionally 
graphitic quartz-schist, rich in sillimanite. The paper gives geological 
sections at Port Henry, and in western Moriah township, to show these 
relations. A most peculiar exposure in the Keene Valley, and well 
within the great anorthosite ridges, is also described, together with its 
intruded rocks— which are very similar to the Saxon granulites. In 
conclusion, the author briefly summarizes his conception of the rocks 
as a metamorphosed series of impure calcareous sediments. 
The Stratigraphy of the Kansas Coal Measures ; Division of Kansas 
Coal Measures; The Coal Fields of Kansas: By ERAsMusS 
Hawortu. Kan. Univ. Quart., Vol. IIl1., April 1, 1895, pp. 271- 
309, with two plates. 
The articles with the above titles are summaries gleaned from 
chapters already prepared for Volume I. of the University Geological 
Survey of Kansas, which it is hoped will be completed during the 
year. Under the first heading is given a general description of the 
principal limestones and shale beds from the base of the Coal Measures 
to the Cottonwood Falls limestone, a vertical distance of 2500 feet or 
more. At the base of the column lie the heavy Cherokee shales, 
which are the principal coal-bearing shales of the state. Above these
