field in mineralogy takes in a good deal of what is useful in geology ; 

 and considering the practical utility of mineralogy, what an important 

 factor it has been, is and will be for all time in civilized progress, it

 if they would give more attention to this live, practical science. Take 

 a little time off from their devotion to the Silurian, Devonian and 

 Carboniferous ages, and get acquainted with the home habits of gold, 

 silver, iron, lead, zinc, aluminum, silicon, carbon, sulphur, sodium, 

 potassium, etc., and try to catch up with the twentieth century that 

 now, like a great globe of light, is lifting its disk above the horizon 

 to light us on to a future of wonderful possibilities.
