Something told the wild geese
It was time to go;
Though the fields lay golden
Something whispered, - 'snow'.
Leaves were green and stirring,
Berries, luster-glossed,
But beneath warm feathers
Something cautioned, - 'frost'.

All the sagging orchards
Steamed with amber spice,
But each wild breast stiffened
At remembered ice.

Something told the wild geese
It was time to fly -
Summer sun was on their wings,
Winter in their cry.
