Why, let me ask, should a hen lay an egg which egg can become a chicken in about three weeks and a full-grown hen in less than a twelvemonth, while a clergyman and his wife lay no eggs but give birth to a baby which will take three-and-twenty years before it can become another clergyman? Why should not chickens be born and clergymen be laid and hatched? Or why, at any rate, should not the clergyman be born full grown and in Holy Orders, not to say already beneficed? The present arrangement is not convenient, it is not cheap, it is not free from danger, it is not only not perfect but is so much the reverse that we could hardly find words to express our sense of its awkwardness if we could look upon it with new eyes, or as the cuckoo perhaps observes it.
