★Listen to part of the talk in an Archaeology class
Now we discuss the proper way to dig the artifacts in an archaeological site, let's turn on our attention to the kinds of objects we might excavate there and what they could tell us about colonial life here on the east coast of North America. One thing we hope to learn when we study the buttons or the broken issues or other artifacts that recovered from the site is just how long ago people were living there. So one of the most useful finds obviously would be a coin. That even the object doesn't have a year stamp right on it can still have the archaeologists to determine just when the site was being used. For instance one object of 1600 and 1700 you likely find is the clay pipe. Smoking was common then but not cigarettes. Tobacco was generally smoked in long thin pipes---clay pipes manufactured in England. These imported clay pipes were so cheap that even the poor could afford to use them and then just threw them away. That's why they were so common throughout the colonies and why we find so many broken and discard pipes in archaeological digs. But the style of the clay pipe, the shape of the bowl, the link of skin, the diameter of the hole all involved of the years. So we can decide seriously precise date of a pipe just by looking at it and comparing it to the similar pipe we already know the age of. And that information looks like how long ago settlers were living in that site and can help date the other artifacts found there. Let me pose here and ask you now what you think some of the other common objects might be and what we might be able to learn from them.
