SUMMIT 



OF THE 



MOUNTAIN OF ORGANOS, 



AT ACTOPAN. 



PLATE LXIV. 



The porphyritic mountain of Mamanchota, 

 known at Mexico under the name of los Organos, 

 is situate to the north-east of the Indian village 

 of Actopan. The spindle-shaped summit of bare 

 rock is a hundred metres in height; but the 

 absolute elevation of the top of the mountain, 

 from which the Organos rises, is 1385 toises. It 

 is on the road from Mexico to the mines of 

 Guanaxuato, that the rock of Mamanchota is 

 seen at a very great distance detaching itself 

 from the horizon ; and, towering amidst a forest 

 of oaks *, it exhibits a very picturesque appear- 

 ance.
