CHAPTER I
Ice-Boating on the Bay
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.
The long cold snap had caused rejoicing in the hearts of the young folk of Bayport. Although the ice in mid-bay was not solid, along the shore and in the numerous coves of the indented bay it was frozen to a safe depth. The dark figures of skaters sped like swallows in flight on the miniature natural rinks close to shore, and farther out the speeding ice-boats with their billowing sails resembled huge sea gulls as they raced before the wind.
Frank Hardy, a dark, handsome boy of sixteen, was at the tiller of the craft that represented several weeks’ hard work on the part of himself and his brother Joe. Although it was homemade, the ice-boat was staunch and stoutly built and as it sped over the gleaming surface the boys were justifiably proud of their handiwork.
“This is great!” shouted Frank. “Ice-boating beats motor-boating all to pieces.”
Joe, a fair, curly-haired youngster who was a year Frank’s junior, was sitting forward with their chum, Chet Morton.
“I’ll say it is!” he agreed. “I don’t think there’s a faster boat on the bay.”
