the increase in temperature: (2) by decrease in pressure; (3) by abstraction of the 

 carbon dioxide to supply plant food. 



Maps of many of the lakes are presented with a legend by which the marl con- 

 ditions may be easily read. The descriptions in the text are full, and the value and 

 accessibility of marl in each lake is clearly indicated. 

 Breeze, Fred, J. The Valley of the Lower Tippecanoe River. Proc. 



Indiana Acad. Sci., for 1901, pp. 215, 216, 1902. 



A map and description set forth the width of the valley and meanders of the 

 stream. 

 Campbell, John T. Evidence of Local Subsidence in the Interior. Jour. 



Geol., Vol. IX, pp. 437, t38, 1901. 



Recent levelings of a locality in western Indiana, where bench-marks were estab- 

 lished in 1883, show a slight decline southward. The Charlestown earthquake is 

 suggested as a cause for the subsidence. 

 Dryer, C. R. Eskers and Esker Lakes of Northeastern Indiana. Jour. 



Geol., Vol. IX, pp. 123-29, 1901. 



The name "esker lakes" is suggested for bodies of water occupying depressions 

 closely connected with esker ridges.

The drainage and Pleistocene deposits are the chief topics pertinent to this 

 review. The main drainage lines of southwestern Indiana became re-established 

 after glaciation, but many of the smaller streams have suffered deflections or diver- 

 sions as a result of an obstruction by the ice-sheet, drift, or glacial outwash. Little 

 Pigeon and Cypress creeks, however, have been but slightly affected. 



The Illinoian drift-sheet constitutes the main member of the glacial series 

 within this quadrangle. There are deeply oxidized sand and gravel deposits found in 

 patches outside the limits of the well-defined drift-sheet and also scattered pebbles, 

 which may prove to belong to an older sheet of drift than the Illinoian. There are 

 also a loess and a black soil beneath the Illinoian drift which are of undetermined 

 age. The main deposit of loess is found above the Illinoian drift and is apparently 

 of lowan age. The loess along the Wabash valley up to a certain level is stratified, 

 occurs in definite terraces, and appears to be of aqueous deposition, while at higher 

 levels it is thought to be wind-deposited. Certain sand deposits along White River 

 valley are considered of Wisconsin age, but most of the alluvium is post-Wisconsin. 

 Heiney, W. N. River Bends and Bluffs. Proc, Indiana Acad. Sci. for 1900, 

 pp. 197-200, 1 901. 



The paper discusses a very crooked section of Salamonie River in southern 

 Huntington county, Ind., and is illustrated by sketch maps and a profile showing how 

 the bend has been extended by the stream.

This paper dissents from interpretations made by Chamberlin and Leverett that 

 in the Wisconsin stage of glaciation the ice from the Huron-Erie basin covered Tippeca-
