Henry Thoreau and His Lichen Repasts

Alexander Theroux

A nose he had on him,
sniffing the bark of twigs,
sitting alone in the forest
listening to the dry creak 
of hardwoods in the fall
and, chewy as any figs,

sampling the tangy tastes 
of lichen like a moose,
especially black stone flower
and tiny fans of rock tripe—
umbilicaria—with pine nuts
he efficiently put to use

by brewing a bracing tea, 
squatting like a coureur de bois.
He enjoyed reindeer lichen,
cold-hardy, by taking it dry,
crushing and then boiling it, 
like leaves of Ceylon regular,

soaking it in water until soft. 
eating it mixed with berries, 
fish eggs, or lard. (He used it
also as diarrhea cure for lichen
gas, blessing its juice and
the many ways Nature varies!)
