2Above the base are placed two beams, projecting six feet on each side; round the projections of which two other beams are fixed in front, seven feet long, and their width and thickness as described for the base. Upon this frame which is to be morticed, posts are placed, nine feet high, exclusive of their tenons, one foot and a palm square, and a foot and a half distant from each other. These are tied in at top by means of morticed beams. Above these beams are braces, with tenons, the end of one being let into the next to the height of nine feet, and over the braces is a square piece of timber, by which they are connected.
2Let two beams be laid on the base, projecting for six feet on each side, round the projections of which let two other beams be nailed, projecting seven feet beyond the former, and of the thickness and breadth prescribed in the case of the base. On this framework set up posts mortised into it, nine feet high exclusive of their tenons, one foot and a quarter square, and one foot and a half apart. Let the posts be tied together at the top by mortised beams. Over the beams let the rafters be set, tied one into another by means of tenons, and carried up twelve feet high. Over the rafters set the square beam by which the rafters are bound together.
