34 INDIANS OF THE SOL'THWEST. 



A round tower rising from the summit of a block of 

 rock reaches the roof of the cave. It has been supposed 

 that this served as a watch-tower. It may have been 

 that the whole structure was intended as a place in 

 which the reserve food supply might be stored and 

 defended, since in the neighborhood are ruins of other 

 community structures in less easily defended situations. 



Spruce Tree House. About two miles northeast in 

 an adjoining canyon is another cave with a dwelling 

 nearly as large and much better preserved. It is 

 named Spruce Tree House from a tree found growing 

 in the ruins which when cut in 1891 showed an age of 

 169 years. In this dwelling are several ceilings in a

 J. W. Fewkes and it is expected that they will remain in 

 this condition as permanent examples of such structures. 



Balcony House. Not far from Cliff Palace and in the 

 same canyon is Balcony House, named so because one 

 of the balconies below the doors of an upper story was 

 found intact by Nordenskiold who describes it as 

 follows: 



"The second story is furnished, along the wall just mentioned, with a 

 balcony; the joists between the two stories project a couple of feet, 

 long poles lie across them parallel to the walls, the poles are covered with 

 a layer of cedar bast and, finall5% with dried clay. This balcony was 

 used as a means of communication between the rooms in the upper 

 Btory." 



Dulce Ruin. A good example of a small cliff-dwelling 

 is situated in the extreme eastern border of the San 

 Juan watershed about twelve miles southwest of Dulce,
