File:JapanHomes081 TILED RIDGE OF THATCHED ROOF IN MUSASHI.jpg

English: From original book: "After getting south of Sendai, ridges composed of tile are often to be seen, — becoming more common as one approaches Tokio. The construction of this kind of ridge is very simple and effective; semi-cylindrical tiles, or the wider forms of hon-gawara, are used for the crest, and these in turn cap a row of similar tiles placed on either side of the ridge (fig. 80). The tiles appear to be bedded in a layer of clay or mud and chopped straw, which is first piled on to the thatched ridge. In some cases a large bamboo holds the lower row of tiles in place (fig. 81). What other means there are of holding the tiles I did not learn. They must be fairly secure, however, as it is rare to see them displaced, even in old roofs."
