"Driven by a stiff breeze from the west, a trim little ice-boat went scudding over the frozen surface of Barmet Bay. The winter air was cold and clear, the hills rising from the shores were blanketed in snow, and although a patch of black water away off toward the east gave evidence that King Frost had been balked at the Atlantic, the bay itself was a gleaming sheet of ice."
