The previous section has shown how quickly a rhyme passes from one school child to the next and illustrates the further difference 41 between shcool lore and nursery lore. In nursery lore a verse, learnt in early childhood, is not usually passed on again when the little listener 42 has grown up, and has children of their own, or even grandchildren. 43 The period between learning a nursery rhyme and transmitting it may be something from twenty to seventy years. With the playground 44 lore, therefore, a rhyme may be excitedly passed on within the very hour 45 it is learnt; and in the general, it passes between children of the 46 same age, or nearly so, since it is uncommon for the difference in age between playmates to be more than five years. If therefore, a playground rhyme can be shown to have been currently for a hundred years, or 47 even just for fifty, it follows that it has been retransmitting over and over; very possibly it has passed along a chain of two or three 48 hundred young hearers and tellers, and the wonder is that it remains live 49 after so much handling, to let alone that it bears resemblance to the orginal wording. 50
