It was this air that Mr. Jerry's dog, as already related, ground out of the barrel-organ, but, besides this particular melody, we do not find that Dickens mentions any other hymn-tune. The hymns referred to are rather more in number. In _The Wreck of the Golden Mary_ Mrs. Atherfield sang Little Lucy to sleep with the Evening Hymn. There is a veiled reference to Ken's Morning Hymn in _O.C.S._, where Sampson Brass says: 'Here we are, Mr. Richard, rising with the sun to run our little course--our course of duty, sir.' Dr. Watts makes several appearances, Dickens made the acquaintance of this noted hymnist in early youth (see p. 7), and makes good use of his knowledge. In _The Cricket on the Hearth_ Mrs. Peerybingle asks John if he ever learnt 'How doth the little' when he went to school. 'Not to quite know it,' John returned. 'I was very near it once.' Another of the Doctor's hymns is suggested by the behaviour of the Young Tetterbys (_H.M._). The contentions between the Tetterbys' children for the milk and water jug, common to all, which stood upon the table, presented so lamentable an instance of angry passions risen very high indeed, that it was an outrage on the memory of Dr. Watts. The pages of history abound with instances of misguided amateurs who have amended the hymns (and tunes) of others in order to bring them into their way of thinking, and a prominent place in their ranks must be assigned to Miss Monflathers (_O.C.S._), who managed to parody the good Doctor's meaning to an alarming extent and to insist that In books, or work or healthful play[16] is only applicable to _genteel_ children, while all poor people's children, such as Little Nell, should spend their time. In work, work, work. In work alway, Let my first years be passed, That I may give for ev'ry day Some good account at last, which is far from the good Doctor's meaning. Dr. Strong, David Copperfield's second schoolmaster, was fond of quoting this great authority on mischief, but Mr. Wickfield suggests that Dr. Watts, had he known mankind well, would also have written 'Satan finds some mischief still for busy hands to do.' Some years ago a question was raised in _Notes and Queries_ as to the identity of the 'No. 4 Collection' of hymns which appeared to afford consolation to Job Trotter. No answer was vouchsafed, the fact being that the title is a pure invention, and no such collection has ever existed. It is scarcely necessary to add that history is silent as to the identity of the hymn-book which Uriah Heep was reading when David Copperfield and others visited him in prison.
