"It is saying less than the truth to affirm that an excellent book (and the remark holds almost equally good of a Raphael as of a Milton) is like a well-chosen and well-tended fruit tree. Its fruits are not of one season only. With the due and natural intervals, we may recur to it year after year, and it will supply the same nourishment and the same gratification, if only we ourselves return to it with the same healthful appetite."
