26 CONNECTICUT GEOL. AND NAT. HIST. SURVEY. [Bull. 



U. S. Geol. Surv., 7th Ann. Rept., for 1885-86, 455-490, 

 I pi, 1888. Abstract: Am. Geol., iv, 112, 113, 1889. 



Discussion of the conditions of accumulation of sandstones, shales, 

 limestones, intrusive and extrusive flows, dikes. Discussion of the 

 structure of the formation, — general attitude, faults and their sys- 

 tematic arrangement, low folds. Discussion of the mechanical origin 

 of the formation. (See Davis, 98.)

 cut valley.

Discussion proving that the disturbance of the strata took place after 

 the period of deposition; was not caused by overflow or intrusion of 

 trap sheets; was not a single monoclinal tilting. The whole region has 

 been cut by a series of strike faults. Discussion of origin of crescentic 

 ridges, and of probable character of the disturbing force. (See Davis, 

 98.)

Results of a study on the mechanical origin of the Trias- 

 sic monoclinal in the Connecticut valley. 



Boston Soc. Nat. Hist., Proc, xxxiii, 339-341, 1886. 



Explanation of the Triassic monoclinal given in the following state- 

 ment: "Whenever unconformable masses are deformed together, the 

 structure given to the lesser, relatively superficial mass must depend in 

 great part on the changes in the surface shape of the greater, deeper 

 mass below." Schists and gneisses have slipped on each other because 

 of lateral pressure. Proof: strike of surface faults corresponds with 

 the strike of the schist beneath.
