Land-tracts during the Secondary and Tertiary Periods. 271 



It is remarkable how the general direction of all the tertiary 

 anticlinals, with two exceptions, coincides with the direction of 

 the existing volcanic bands (other than the Andes), the most im- 



the above systems, anticlinals, and bands, the numbers following referring 

 to the corresponding numbers above : —

Cuba, Yucutan, and the chain of active volcanoes crossing Central 

 Mexico from E. to W. belong probably to this system.
