old, and other frame structures of a larger size and of far greater age, which presented no visible signs of weakness. Indeed, it is a very unusual sight to see a broken-backed roof in Japan.

Diagonal bracing in the framework of a building is never seen. Sometimes, however, the uprights in a weak frame are supported by braces running from the ground at an acute angle, and held in place by wooden pins. Outside diagonal braces are sometimes met with as an ornamental feature. In the province of Ise one often sees a brace or bracket made out of an unhewed piece of timber, generally the proximal portion of some big branch. This is fastened to an up-right, and appears to be a brace to hold up the end of a horizontal beam that projects beyond the eaves. These braces, however, are not even notched into the upright, but held in place by square wooden pins, and are of little use as a support for the building, though answering well to hold fishing-rods and other long poles, which find here convenient lodgment (Fig. 7).

The framework of a building is often revealed in the room in a way that would delight the heart of an Eastlake. Irregularities in the

form of a stick are not looked upon as a hindrance in the construction of a building. From the way such crooked beams are brought into use, one is led to believe that the builder prefers them. The desire for rustic effects leads to the selection of odd-shaped timber. Fig. 4 represents the end of a room, wherein is seen a crooked cross-piece passing through a central upright, which sustains the ridge-pole.

As the rooms are made in sizes corresponding to the number of mats they are to contain, the beams, uprights, rafters, flooring-boards, boards for the ceiling, and all strips are got out in sizes to accommodate these various dimensions. The dimensions of the mats from one end of the empire to the other are approximately three feet wide and six feet long; and these are fitted compactly on the floor. The architect marks on his plan the number of mats each room is to contain—this number defining the size of the room; hence, the lumber used must be of definite lengths, and the carpenter is sure to find these lengths at the lumber-yard. It follows from this that but little waste occurs in the construction of a Japanese house.
