498 NAVAHO HOUSES (ETH ANN. 17 
Figure 239 shows a form that occurs in the valley regions where drift- 
wood can sometimes be obtained. It is closely related to the “lean-to” 
type, but it is formed partly by excavating the side of a hill and is 
well covered with earth. It will be noticed that the front is partly 
closed by logs leaned against it and resting against the front cross- 
piece or ridgepole. 
Figure 240 shows a type which is common in the valleys where timber 
is scarce and difficult te procure, Sage and other brush is used largely 
in the construction of shelters of this sort, as the few timbers which are 
Fie. 238—A timber-built shelter 
essential can be procured only with great difficulty, ana usually must 
be brought a great distance. 
Plate LXXxxvit shows a structure that might easily be mistaken for a 
summer shelter, but which is a special type. It is a regular hogan, 
so far as the frame and timber work go, but it is covered only with 
cedar boughs. The illustration shows a part of the covering removed. 
This structure was a “medicine hut,” put up for the performance of 
certain ceremonies over a woman who was ill. There are no traces of 
any fire in the interior, perhaps for the reason that the women’s cere- 
mony is always performed in the day time. Aside from its lack of 
covering, it is a typical hogan, and the illustration conveys a good 
impression of the construction always followed. This kind of hut is 
called an ingd gogdun.
