Thanks for the reply, but I don't think so ,the big squares are houses and the sheds are marked, it might look a tad smaller on map this is just a rough draft. You usually see them out of the way and some times with not much around them that's why I thought it might be a trough for horses, its shaped like that . you could be right I just seen them
on a lot of maps and they where never marked so I would think they were insignificant .It is in the horse and buggy era.
