Geology Definition
Geology n.:
The science of the Earth's crust- to which, doubtless, will be added that of the its interior whenever a man shall come up garrulous out of a well. The geological formations of the globe already noted are catalogued thus: The Primary, or lower one, consists of rocks, bones or mired mules, gas pipes, miners' tools, antique statues without the nose, Spanish doubloons and ancestors. The Secondary is largely made up of red worms and moles. The Tertiary comprises railway tracks, patent pavements, grass snakes, mouldy boots, beer bottles, tomato cans, intoxicated citizens, garbage, anarchists, snapdogs and fools.
