It is, however,able to boast a surface of 197,124,000square miles, and a planetary massamounting to 256,000 millions ofcubic feet. All this matter is inconstant motion. The changeless,fltJiffi rocks are never at rest, *^ As the earth itself is in motion, so are its component parts. Gradualchanges are being wrought throughthis activity.
