In some instances the rectangular corner hood is not suspended from the ceiling, but is supported from beneath by a stone slab or a piece of wood. Such a chimney hood seen in a house of Shupaulovi measures nearly 4 by 5 feet. The short side is supported by two stone slabs built into the wall and extending from the hood to the floor. Upon the upper stone rests one end of the wooden lintel supporting the long side, while the other end, near the corner of the room, is held in position by a light crotch of wood. Fig. 64 illustrates this hood; the plan indicating the relation of the stones and the forked stick to the corner of the room. Fig. 71, illustrating a terrace fireplace and chimney of Shumopavi, shows the employment of similar supports. Corner chimney hoods in Zuñi do not differ essentially from the more symmetrical of the Tusayan specimens, but they are distinguished by better finish, and by less exposure of the framework, having been, like the ordinary masonry, subjected to an unusually free application of adobe. [Illustration: Fig. 64. A chimney hood of Shupaulovi.] The builders of Tusayan appear to have been afraid to add the necessary weight of mud mortar to produce this finished effect, the hoods usually showing a vertically ridged or crenated surface, caused by the sticks of the framework showing through the thin mud coat. Stone also is often employed in their construction, and its use has developed a large, square-headed type of chimney unknown at Tusayan. This is illustrated in Fig. 65. This form of hood, projecting some distance beyond its flue, affords space that may be used as a mantel-shelf, an advantage gained only to a very small degree by the forms discussed above. This chimney, as before stated, is built against one of the walls of a room, and near the middle. [Illustration: Fig. 65. A semi-detached square chimney hood of Zuñi.] [Illustration: Plate LXXXIV.
