According to Leibniz

When the mojo is
working, ivory 
can be found
within the pith of 
sugarcane. It 
is said to be 
environmentally
friendly, lighter 
than air, can be 
posted without an 
envelope. Only 
the Letters of a 
Portuguese Nun 
are a poignant 
exception, but 
even they display 
a similar charge, 
obey the same 
mass magnitude.   
In summer, when
the louvers are
left open & the 
songs of the no
longer endangered 
species float in
from the desert, 
it is the best of 
all possible worlds.
