Hi I think i finally have the right forum. ^^ Anyways I have a project It;s about the first nations ppl called the iroquois. I'm doing a model of the house. It's a longhouse but i have no idea which version of the long house is the traditional kind. Is it the one with the whoel thing round or the one with it straight n teh sides. I need the one that the europeans have not influenced the Iroquois yet and i'm not sure if there were 2 versions of the model of the europeans influenced them on.

here is the picture of the one that is al round

and this one is the picture of the the one that are straigh tat the ends.
Please remember to thumb your pictures. - My Cinderella.
