THE BRAIN OF THE EARTH

 earth, there appeared the beginnings of the soil 

 of today. Other agents were at work besides 

 the ice-mills before the soil was brought into 

 proper condition for the production of vegeta- 

 tion for the enrichment or the adornment of 

 the earth. Some geologists, who have studied 

 the great frame of the earth, have maintained 

 that its surface was once a massive, unyielding 

 shell of rock, barren, without sign of life, fit

 soils, rich or lean, ground by the great glaciers, 

 the ice-mills of God; broken up by the alter-

 eons of pre-historic times, the water wearing 

 off particles and transporting them in solution 

 to be deposited on level plains or along lake 

 and waterways ; disintegrated by certain early,

 the great ice-mills, — a mighty, age-long pro-

 today, fully furnished and prepared for the use 

 of man.
