the origin of the secondary rocks. What factors 

 or forces entered into the production of the vast 

 variety of stratified rocks, differing as widely from 

 the original Adam rock, the granite, as the races 

 of men differ from one another? There is just as 

 much room for natural selection to work in one 

 case as in the other. We find where two kinds of 

 rock touch, one overlying the other, and absolute 

 difference in texture and color, and no union be- 

 tween them. How account for their juxtaposition ? 

 Rock begat rock, undoubtedly, and the aerial forces 

 played the chief part, but the origin of each kind 

 is hidden in the abyss of geologic time, as is that 

 of the animal species. 



The position of the camel with reference to the 

 giraffe in Africa is analogous to that, say, of the 

 Catskill conglomerate to the laminated sandstone 

 that lies beneath it. They are kindred; one gradu- 

 ates into the other. Whence the long neck and 

 high withers of the giraffe? The need of high feed- 

 ing, say the selectionists, but other browsing ani- 

 mals must have felt the same need. Our moose is 

 strictly a browsing animal, and, while his neck and 

 shoulders are high, and his lips long, they do not 

 approach those of the giraffe. The ostrich has a 

 long neck also, but it is a low feeder, mainly from 

 the ground. % 



We can only account for man and other higher 

 forms of life surviving in the highway of the physi-
