In an old photograph of themselves, which they were one day to give me, and which I have kept ever since, their infantile troop already presents the same number of participants as, later, their feminine procession; one can see from it that their presence must, even then, have made on the beach an unusual mark which forced itself on the attention; but one cannot recognise them individually in it save by a process of reasoning, leaving a clear field to all the transformations possible during girlhood, up to the point at which one reconstructed form would begin to encroach upon another individuality, which must be identified also, and whose handsome face, owing to the accessories of a large build and curly hair, may quite possibly have been, once, that wizened and impish little grin which the photograph album presents to us; and the distance traversed in a short interval of time by the physical characteristics of each of these girls making of them a criterion too vague to be of any use, whereas what they had in common and, so to speak, collectively, had at that early date been strongly marked, it sometimes happened that even their most intimate friends mistook one for another in this photograph, so much so that the question could in the last resort be settled only by some detail of costume which one of them could be certain that she herself, and not any of the others, had worn.
