Jack Radburn, mate of the "Lily," was as prime a seaman as ever broke biscuit. Brave, generous, and true, so said all the crew, as did also Captain Haiselden, with whom he had sailed since he had first been to sea. Yet so modest and gentle was he on shore that, in spite of his broad shoulders and sun-burnt brow, landsmen were apt to declare that "butter wouldn't melt in his mouth."
