 because it is a matter of daily experience, but it is 

 not easy to believe that man is born of the animal 

 world below him, and that that is born of inorganic 

 Nature, because the fact is too big and tremendous.

 and distance of the fixed stars. 



No observation or study of evolution on a small 

 scale and near at hand in the familiar facts of the 

 life about us can prepare us for it, any more than lake 

 and river can prepare us for the ocean, or the model- 

 ing of miniature valleys and mountains by the rain 

 in the clay bank can open our minds to receive the 

 tremendous facts of the carving of the face of the 

 continent by the same agents. 



We do not see evolution working in one day, or in

 catch the gods of erosion at their Herculean tasks. 

 They always seem to be having a holiday, or else to

 and gulches by the rains of a season, we do not
