Geology, n. The science of the Earth's crust-to which, doubtless, will
be added that of it's 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 of
mired mules, gas-pipes, miners' tools, antique statues minus the nose,
Spanish doubloons and ancesters. 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, snap-dogs and fools.
