back or else dangled beside her while she walked the mountains. This was not surprising, since all infants after a certain
age start riding their mothers rather than clinging on beneath; but we were astonished to see that Fifi, when next we saw
her take Flint, also tried to push him onto her back. This was surely an example of learning by direct example of her
