Note 30 — Chapter VIII · Conclusion.

But these simple compounds with a single foreign theme do not complete the tale. When once they were formed, they in turn had each a history of its own, with infinite possibilities of absorbing traits from other stories or even entire themes. In the case of the latter, a reason could always be found in such points of contact as I have already mentioned, or so I believe, if the material were sufficient for proper comparison. In this way arose the complicated types treated in chapter six, where the manner of combination is readily seen.30 Sometimes, it is probable, subtraction has taken place as well as addition, but apparently only when it has not involved the disentangling of various traits. For example, many variants have been noted where one of the two most striking features of our central theme, the burial of the dead debtor, has disappeared; yet in every case the rest of the plot has remained unimpaired. The more complicated the variant, the better able is the investigator to place its kinship to other variants, provided that he has the requisite material and the patience to follow up the clues that every such labyrinth affords.
