REPORT OF THE SECRETARY 75 



The first week in September found liim at Folsom, N. Mex., where 

 workmen of the Colorado Museum of Natural History, Denver, had 

 uncovered several projectile points in direct association with the 

 bones of an extinct species of bison, Bison tayloH. Several days 

 were spent in investig-ating the fossil bed and the surrounding terri- 

 tory. Doctor Roberts was so impressed with the find that he sent for 

 Dr. A. V. Kidder, of the Andover Academy and the Carnegie Insti- 

 tution of Washington, and with him again Avent carefully over the 

 problem presented. At the conclusion of the investigations Doctor 

 Roberts and Doctor Kidder were convinced that the bones and the 

 projectile points had been deposited in the stratum contem- 

 poraneously. He returned to Washington early in October. 



The winter was spent in the preparation of a manuscript on the 



season's work, entitled " Shabikeshchee Village, a Late Basket-Maker 



Site in the Chaco Canyon, New Mexico." Another manuscript 



. entitled " Recent Archeological Developments in the Vicinity of 



El Paso, Tex.,"' was also completed. 



In February Doctor Roberts went to Melbourne, Fla., to view, in 

 situ, a projectile point which Dr. J, W. Gidley, of the United States 

 National Museum, had found in a stratum from which he was remov- 

 ing the bones of extinct Pleistocene animals. The projectile point 

 and bones were from the same stratum which in previous work had 

 yielded the crushed skull of a human being. It is around the latter 

 that much anthropological and paleontological discussion has centered 

 during the last two years. Doctor Roberts took advantage of the 

 trip to Melbourne to visit a number of shell heaps and mounds left 

 by some of the earlier Indian inhabitants of the region. 



In May, 1928, Doctor Roberts made a reconnaissance along the 

 San Juan River to a point about 10 miles south of Rosa, N. Mex. 

 Returning to Arboles, Colo., a short survey and inspection was made 

 of the ruins and ruin sites along the Piedra River, one of the larger 

 tributaries of the San Juan. As a result of the latter it was deter- 

 mined to excavate a site located on a bluff 100 feet above the river 

 on the east side of the Piedra 15 miles north of Arboles. 



The month of June was spent in an intensive investigation of the 

 above site, which proved to be a Pueblo I village. Of the 24 houses 

 excavated, 21 were single-room structures. Of the remaining 3, 2 

 had been 2-room domiciles, while the third had contained three 

 cell-like rooms. It was found that the structures varied considerably 

 in size, some of them being but 5 to 6 feet square, while others were 

 25 to 30 feet in length by 6 to 9 feet in width, but all had been 

 constructed in the same manner. In most cases there had been a 

 slight excavation measuring from 6 inches to 1 foot in depth. This 

 pit portion of the dwelling, if the slight excavation ma}' be so called.
