For the same reason the boards of the floor arc laidacross the veranda, as shown, as the water would otherwiselodge in the joints and soon rot out the material. In order to run the floor boards in this direction, it isnecessary to provide means of framing- the floorbeams length-wise of the structure. Therefore, under each veranda postis built a brick or stone pier «, on which is laid the 4 X 0sill _/extending-full length of the veranda, and from this.
