It will probably be said, that however well adapted the plan recommended may be for the infantine scholars for whom it was designed, yet, it does not follow that it may be equally advantageous for those of a more advanced age; and if by this it is meant, that the very same lessons, &c., are not equally applicable in both cases, I perfectly agree with the truth of the objection; but it is the principle of education that I recommend, and would affirm to be as applicable to children of the most advanced age, as to those of the youngest.  And I may further add that unless this is done, these schools will not be in a proper state to receive our children, so as to carry on the cultivation of all the faculties, instead of the memory only.  It is not sufficient to store the memory, we must give employment to the understanding.  It is not sufficient to talk to the children of piety and of goodness; we must present them with a living example of both, and secure, as far as possible, an imitation of such example.

As applicable to Sunday Schools, I would particularly recommend the use of picture lessons on scripture subjects, for the use of the junior classes, to be used as a sort of text for conversation, suited to the state of their mental faculties.  I am convinced that the knowledge acquired by this method is likely to make a deeper and more lasting impression, than that imparted in a less interesting mode.  Nor should the lessons on natural history be neglected, in my humble opinion, in the system of Sunday School instruction; inasmuch as the more the children know of the wonders of creation, the greater must be their reverence of the Almighty Creator; in addition to which it will enable the teachers to supply variety, a thing so agreeable, and, indeed, indispensable, in the instruction of children.  For these reasons, I think it could not justly be considered as either a misemployment or profanation of the Sabbath-day.  For the elder children, moreover, it would be advisable to have occasional class lectures, simplified for the purpose, on astronomy, natural history, &c.; and although it might be unadvisable to occupy the hours of the Sabbath-day with the delivery of them, they might be given, on some week-day evening, and should be made the medium of reward to good behaviour; such children as had misbehaved themselves being proscribed from attending.  When thus seen in the light of a privilege, they would not fail to be interesting to the little auditors, as well as conducive to good behaviour.

Sunday Schools should not be too large, nor should children remain in them too long.  I have observed some instances, when this has been neglected, of choices being made, and connections formed, which must be often very prejudicial.
