In response to Joshua Piker's (this issue) comment on our article (Foster and Cohen 2007), we point out that our article was a description of a test of a hypothesis. Piker's (this issue) criticism of our paper is grounded in the differences between historians and anthropological archaeologists. The historic literature that Piker (this issue) cited does not inform about whether or not Creek Indians hunted where we performed the sediment cores. It merely points out that Creek hunters may have hunted with greater frequency elsewhere. But that is irrelevant to our study, which tested whether the eighteenth-century deerskin trade increased the frequency of forest fires in a particular region. Archaeologists will benefit from using historical documents but archaeologists still have to be clear about the potential biases of those interdisciplinary data sources.
