A Farmer, being at death's door, and desiring to impart to his Sons a secret of much moment, called them round him and said, "My sons, I am shortly about to die; I would have you know, therefore, that in my vineyard there lies a hidden treasure. Dig, and you will find it." As soon as their father was dead, the Sons took spade and fork and turned up the soil of the vineyard over and over again, in their search for the treasure which they supposed to lie buried there. They found none, however: but the vines, after so thorough a digging, produced a crop such as had never before been seen.
