we would call this a petri dish today, but julius petri is a 19th century german scientist, so it's a little before his time. and on the tables here you can see a lot of native pottery. and i am in the process of trying to mend those together. with native pottery it's a bit more difficult than with other wares because the colors don't change too much. so, this is a typical native pattern of our indians and it's called simple stamping. so, it's a leather-wrapped paddle that they are heating the sides with. sometimes they smooth the pattern out. so, it's a base of a pot there. but you can see everything gets numbered. all the little pieces get numbered with the area of the fort that where they were found. and that's one of the processes we do in the lab. and we keep track of those numbers. because if one feature should mend to another across the site, that's a very important thing to note, you know, if things from the well mend with things from the ditch, then that means that both those features were open at the same time, so that's an important step. it's called cross mending. >> hi, w
