ANOTHER GREAT WALL

The Great Wall of China, winding like a mighty, protecting serpent along the old northern boundary of the Celestial Kingdom–

Hadrian’s Wall, the Great Wall of Britain, built and fortified to shut the barbarians of the north out of southern Britain in Roman days–

And now, added to this small, select list of Great Walls in the world is an American entry–the Great Wall of Peru, which has been discovered by explorers flying over the Andes.
