Mound 1 



[April 



eyes in the majority of the bird pipes were set with pearls from 

 the margaritiferous Unionidae. 



The most valuable specimens of the series, however, are those 

 in the form of the human head, probably " faithfully representing 

 the prominent physical features of the ancient people by whom 

 they were made." 1 Fig. 5 illustrates the most interesting example, 

 in this valuable collection. 2 



Next in importance to the discoveries of Messrs. Squier and 

 Davis, is the collection of mound pipes deposited in the Daven- 

 port Academy of Natural Sciences, and for the greater part taken 

 from mounds by members of that learned body. The series 

 number forty-three specimens of the platform type, consisting of 

 twenty-two with plain or zoned bowls of the " monitor " pattern ; 

 one human head ; seven bi^is, and thirteen other animal forms, 

 of which Mr. W. H. Pratt has kindly sent me photographs. 



An interesting and instructive specimen, in the form of an un- 

 finished pipe, was taken from a mound at Toolsborough, Louisa 

 county, Iowa, which serves' to show, to a certain extent, the man- 

 ner of fashioning such objects. The material is a coarse, soft, 

 cream-colored stone, which has been roughly hewn into the de- 

 sired shape (Fig. 6). The inference to be drawn from the pres- 

 ence of an incomplete pipe in one of the mounds, is either that 

 it was discarded on account of the unsuitableness of the mate- 

 rial, or that it was placed in the tumulus as a substitute for a per- 

 fectly finished specimen which could not be procured at the time 

 when the body it was intended to accompany was deposited. An

 through the courtesy of Professor S. F. Baird, secretary of the Smithsonian Institu- 

 tion, from Dr. Charles Rau's work on the Archaeological Collection of the United 

 States National Museum.
