Ah yes, I know it well - there's the big pattern which is the head & shoulders, then there are those itsy bitsy trades you do to get tiny pieces of the head & shoulders. Dandruff trades, I think they're called. :cheesy:

"Scalping, predated the mid-eighteenth century. Historical records, archaeology, and other sciences strongly indicate the practice originated among certain Native American tribes. A French soldier, identified by the initials J. C. B., related in his memoirs that "this horrible custom was practiced by these savages alone, and sprang from their own barbarism, for it seems never to have existed in any other nation, not even among nations, who, like them, have never received any idea of civilized life."
