GENERAL CONSIDERATIONS. 
In the preparation of this paper it was assumed that the fol- 
lowing general propositions might be taken for granted : 
1. That mountain chains consist principally of sedimentary 
rocks, originally laid down as deposits along continental 
borders or inland seas and subsequently crumpled and up- 
heaved by horizontal pressure. 
2. That there is a general parallelism and successive forma- 
tion of ranges in any one region; the successive formation pro- 
. ceeding coastward.
