 or that through the Farmington valley to New Haven 

 Bay. 



Am. Jour. Sci., (3) xxv, 440-448, maps, 1883. Abridged: 

 Connecticut Almanac, 34-52, map, 1888. 



Arguments showing that the waters of the flooded Connecticut, com-

 the Mill valley rather than the Quinnipiac.

[Review of] " On the relations of the Triassic traps and 

 sandstones of the eastern United States," by W. M. Davis. 

 Am. Jour Sci., (3) xxv, 474-475, 1883. 



Criticism of Davis's view that some of the traps are intrusive and 

 some overflow; exception taken to the " overflow theory." (See Davis, 

 82.) 



58. Dana, J. D. 



Phenomena of the Glacial and Champlain periods about 

 the mouth of the Connecticut valley — that is, in the New 

 Haven region. 



Am. Jour. Sci., (3) xxvi, 341-361, map, 1883; xxvii, 113- 

 130, maps (pis. i, ii), 1883. 



Description and discussion of the glacial phenomena in the New 

 Haven region, including the sand plain and kettle-holes. There were 

 two simultaneous movements of the glacier ice, one southwest, the 

 other southeast.

On the southward ending of a great synclinal in th« Ta- 

 conic range. 



Abstract : British Assoc. Adv. Sci., Rept. 54th meeting, 

 729, 730, 1884. 



The Taconic range is probably of the age of the Hudson river group 

 or Llandeilo flags; a southern portion in southwestern Massachusetts 

 and its continuation into Salisbury, Connecticut, is a broad tray-shaped 

 synclinal; the area south is limestone, which comes out from beneath the 

 dwindled, flattened-out, and worn-off mountain synclinal. (See Dana, 

 61.)

[Review of] " Preliminary paper on the terminal mo- 

 raine of the second glacial epoch," by T. C. Chamberlin. 

 Am. Jour. Sci., (3) xxviii, 228-231, 1884. 



Review of Chamberlin's paper. Discussion of the theory as ap- 

 plied to the Connecticut valley, vihere no facts have been observed 

 which indicate a second glacial epoch.
