While a Main street man was commenting in his family circle last evening on the stubborn way in which the price of eggs remains at the present high figure, his youthful hope asked him if it is not wrong for the newspapers to call eggs hen-fruit. “Yes, my son,” responded the fiendish father, “They are really fruit of the poul-tree.” The boy egg-spired.
