4 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 95 



scratching around the remaining " islands " of top-layer earth A. L. 

 Coffin and Major Coffin uncovered some bones at the original location. 

 On the strength of this evidence, trenches were dug through a portion 

 of the area where erosive action had not completely uncovered the 

 basic stratum. This was a fortunate procedure because, contrary to 

 the impression of the preceding autumn, there was evidence still in 

 situ. A bone pile comprising the remains of several individual bison 

 was located there. Some of the skeletons were partially articulated 

 and, in common with a majority of the separate bones, were in a good 

 state of preservation. Although a number of the bones had been cut 

 and split, the material as a whole was much more satisfactory from 

 the standpoint of the paleontologist than that obtained in the earlier 

 work. It made less debatable the identification of the species of bison 

 present at the site and corroborated the conclusion reached the previ- 

 ous year from very scrappy evidence. 



Besides animal bones, a number of invertebrates were obtained at 

 the site. Identification of the moUusks contributes further to the 

 knowledge of general conditions at the time of occupation. Fragments 

 of charcoal were saved in the hope that the wood could be identified and 

 contribute still more evidence on the physiographic environment. This 

 material is being studied by Dr. Ralph W. Chaney, of the University 

 of California, but no report on it has been received. Samples of the 

 soil in which the remains were found were tested for possible fossil 

 pollens in a further effort to broaden the picture. This work was 

 done by Margaret Kaeiser, of the University of Oklahoma, under 

 the direction of Dr. Paul B. Sears, head of the department of botany 

 at that institution. Unfortunately, there was no evidence of pollen in 

 the dirt. Dr. Paul S. Conger, custodian of diatoms, United States 

 National Museum, examined earth samples for fossil diatoms, micro- 

 scopic unicellular algae that inhabit fresh and salt water, but found 

 none. He noted fragments of sponge spicules, although they were too 

 disintegrated for identification. 



In addition to the work done by the Smithsonian Institution's field 

 party, investigations were conducted at the Lindenmeier site by the 

 Colorado Museum of Natural History, Denver. Their excavations 

 extended from June 14 to September i. Jack Cotter, Harley Goettsche, 

 and Robert J. Lanberg comprised the Denver expedition. J. D. Fig- 

 gins, at that time director of the Denver Museum and now with the 

 Bernheim Foundation near Louisville, Ky., visited the site a number 

 of times while his men were at work there. Mr. Figgins and Mr. 

 Cotter made available to the present writer, for study, all the material
