A Farmer being on the point of death, wished to insure from his sons the same attention to his farm as he had himself given it. He called them to his bedside, and said: "My sons, there is a great treasure hid in one of my vineyards." The sons, after his death, took their spades and mattocks, and carefully dug over every portion of their land. They found no treasure, but the vines repaid their labor¹ by an extraordinary and superabundant crop.
