FEWKEs] GROUP B OK THE BLACK FALLS RUINS 49 



The rooms of the second section (figure S), several of which are well 

 pi-eserved, are lower than those of the first section, and the detritus has 

 covered the base so completely that the mesa is inconspicuous. Room 

 A (plate xiv) is nearly square and is built on two rectangular rocks, the 

 top of which forms the floor. One of these rocks forms a side of the 

 lower story of the adjoining room B, which is in the best condition of 

 any in this section. The walls of this room are well preserved, and 

 it was occupied as a habitation by a herder a few winters ago. There 

 is a lateral doorway through the wall on one side, and in one corner 

 is a fireplace communicating with a chimnej', which Mill later be 

 described. This room is 12 feet -i inches long by 9 feet 7 inches wide. 

 In the second section many walls are still standing high above their 

 foundations, indicating rooms now filled with fallen debris, in which 

 beams, fragments of potterj-, and other objects may be seen. Ten 

 large rooms were counted, several of which had two stories. As has 

 been stated, there were apparently basal rooms on the eastern side. 

 Tlie entire section is about 60 feet long. 



A chimney-like structure (plate xv) is one of the most conspicuous 

 objects in this part of the ruin. It rises from the mass of debris 

 covering room E and communicates with the fireplace in i-oom B, but 

 a vertical line from its top is 7 feet 10 inches from the nearest wall of 

 the room in which the fireplace is situated. "Whether this chimney is 

 aboriginal or not, or whether it is a chimney at all, are open questions. 

 E.xcepting its state of preservation and fine masonry, no evidence was 

 found that it is of more recent date tlian the walls of the rooms. If 

 it is an aboriginal chimney, which is doubtful, its structure is unique. 

 It may be a ventilator, comparable with the chimney-like structures 

 described by Mindeleff in the kivas of Canyon de Chelly. 



One of the finest reservoirs (plate xvi ii) which the author has seen 

 in connection with a ruin was discovered near the bottom of the ele- 

 vation on which ruin A of group B is situated. Tliis reservoir is cir- 

 cular in shape, 50 feet in diameter, and carefully walled. It lies south 

 of the second section of the group, and apparently had a break in the 

 wall in line with the depression east of the ruin. It appears to belong 

 to the same type as those reservoirs on the East mesa of the Hojiis in 

 which snow and rain are collected for future use. 



There are instructive petroglj'phs near ruin a, group b. A number 

 of rock etchings observed in a small canyon about a mile from the 

 ruin were pecked in a perpendicular wall, protected bj'the overhanging 

 rim of the canyon. These petroglj'phs were evidently made by the 

 former inhabitants of this region, as one of the best examples shows 

 the same design as that figured on pottery from the, neighboring ruin. 

 There were likewise butterflj', .sheep or antelope, and other figures. 



It would be quite impossible in this preliminary notice to give a 

 complete account of the archeologic objects which Mr Doney has 

 taken from this ruin, but even a prelimiuarj' sketch would be incom-
