The school was kept by a responsible person of the ancient system; that is to say，we were flogged(鞭打) soundly when we did not get our lessons. We were put into classes and flogged on in groups along the highways of knowledge，in the same manner as cattle are driven to market，where those that are heavy in pace or short in leg have to suffer for the superior quickness or longer legs of their companions.

He sat with his family in a large church bench，reading lessons and lowliness of spirit out of prayer­ books. Whenever the priest spoke of the difficulty of a rich man's entering the Kingdom of heaven，I
