A clergyman had preached on the subject of Jacob's ladder, and his son, who was present, was much impressed. A few days later he told his father that he had dreamed about his father's discourse. "And what did you see, my son?" "I dreamt," replied the boy, "that I saw a ladder reaching from the ground up into the clouds. At the foot of the ladder were many pieces of chalk and no one was allowed to ascend without taking a piece for the purpose of placing a mark on each rung for each sin committed." "Very interesting, my boy, and what else?" "Well, father, I thought I would go up and I marked the rungs as I went, but I hadn't got very far when I heard someone coming down." "Yes," said the father, "and who was that?" "You, father," replied the boy. "I, whatever was I coming down for?" "More chalk," was the reply.
