Madre-de-Agua

In field guides to the giant
creatures of Cuba

the mother-of-water
is a boa constrictor so huge
that muleteers often
mistake it for a palm tree

and in the morning
after leaning against the serpent
in sleep

they awaken to discover
that their mules have been eaten

and the snake has slipped away
into the sea, its giant home, big enough
for dreaming.
