The seasons came and went, and the ponies adopted the New World as their own. They learned to take care of themselves. When summer came and with it the greenhead flies by day and the mosquitoes by night, they plunged into the sea, up to their necks in the cool surf. The sea was their friend. Once it had set them free. Now it protected them from their fiercest enemies.
—Marguerite Henry, Misty of Chincoteague
