"We cannot absolutely know that all these exact adaptations are the result of preconcert. But when we see a lot of framed timbers, different portions of which we know have been gotten out at different times and places, and by different workmen — Stephen, Franklin, Roger, and James, for instance — and when we see these timbers joined together, and see they exactly matte the frame of a house or a mill, all the tenons and mortices exactly fitting, and all the lengths and proportions of the different pieces exactly adapted to their respective places, and not a piece too many or too few, — not omitting even scaffolding — or, if a single piece be lacking, we see the place in the frame exactly fitted and prepared yet to bring such piece in — in such a case we find it impossible not to believe that Stephen and Franklin and Roger and James all understood one another from the beginning and all worked upon a common plan or draft drawn up before the first blow was struck."
