Interesting note here on page 61 that #thomasjefferson was plagued by #samplebias because of the way he decided to excavate the #Monacan burial mound north of Charlottesville. Because of that, and I suspect some racial bias as well, he thought it was thrown together in "utmost confusion". No, we now know there was a clear order because of more modern methods but he could not see it. #archeology
