Mr. Jackson's imaginings, especially when he walked alone amid the majestic scenery that surrounded his dwelling, certainly were poetry; but he seldom interrupted his pleasing reveries, or checked his nights of fancy, to place them on paper, or even to arrange them in any precise order of words. Indeed, it was one of his favourite positions, (and he was famous for theories of his own,) that a man might be a poet, without possessing one word of any language whatsoever, in which to express his poetic ideas. In judging a new work, too, he seldom descended to verbal criticism; but, taking an enlarged view of the spirit in which the thing was written, pronounced it, at once, to want, or to possess, that poetical spark, that vivifying principle, which must, he maintained, breathe a soul into every composition, whether prose or verse, worth the trouble of reading. To complete Mr. Jackson's qualifications for a preceptor, he himself found a sensible pleasure in imparting knowledge. Let others prove the wonders, the properties, the virtues of all that the material world affords; and, admired be their curious, and respected their useful labours; but the natural philosophy in which he delighted, was the development of the young mind. In his mode, too, of communicating instruction, there was a peculiar felicity. He never required of a pupil an arbitrary act of mere memory: "indeed," he would say, "there is no such a power as mere memory." What is commonly called having a good memory, he considered as nothing more than the natural result of fixing the attention, awaking the feelings, and forming the associations. These last, he termed the roots, by which remembrances entwine themselves with our whole constitution, till the very heart vibrates to a sound, a colour, or but the scent of a flower, plucked in the day of joy, or of sorrow. He, therefore, always endeavoured to lead the understanding to facts, through their causes; and, again, to interest the feelings in the consequences of those facts: thus were the lessons he taught never to be effaced. Above all things, he hasted to supply the infant mind with salutary associations, on every subject tending to implant principles and form character; considering every avenue of the soul, not thus timely fortified, as laid open to the incursions of wrong, perhaps, fatal opinions. For instance, whilst others railed, with common-place argument, against bribing children, as they termed it, into goodness; he maintained that the lowest animal gratification of the infant, (that is, before it can understand any other,) may be so judiciously bestowed, as to become the first seed of that grand principle, a thorough conviction that the virtuous only can enjoy happiness. If the child's daily and hourly experience prove to it, that when it is good it has all from which it knows how to derive pleasure; and that when it is not good, the reverse is the case; must
