 stone, the conglomerate, the slate, up into Carbon 

 iferous times. The upper and nether millstones of the

 floods and the convulsions of Carboniferous times 

 that buried the vast vegetable growths that re

 About that time probably, I emerged from the water 

 and became an amphibian, and maybe got my five 

 fingers and five toes on each side. 



Nor did the wholesale destruction of animal life 

 at the end of Palaeozoic time cut off my line of de
