60 CUP-SHAPED AND OTHER LAPIDARIAN SCULPTJJRES. 



I can perceive, however, that their nomenclature in regard to stones bearing' 

 cups and larger cavities is not sufficiently precise. The terms pierres d 

 ecuelles and pierres a hassins are indiscriminately used, whereas, in my 

 opinion, a proper distinction between the two classes of cavities indicated 

 by them might with advantage be made. 



Since my attention was directed to the subject treated in these pages, 

 I have examined many representations of figures sculptured or painted on 

 rocks in the United States, in order to ascertain whether there occur among 

 them any designs analogous to those of the Old World. While engaged 

 in this investigation, I received from Dr. Charles H. Stubbs, of Wakefield, 

 Lancaster County, Pennsylvania, lithographic representations of a sculpt- 

 iired rock, called Bald Friar Rock, in the Susquehanna River, not for from 

 its emboguement into the Chesapeake Bay.* I discovered by means of 

 the lithographs that several figui-es on that rock recall certain types of the 

 lapidarian sculptures of Great Britain, and mentioned the fiict to the Sec- 

 retary of the Smithsonian Institution, Professor Spencer F. Baird, who there- 

 upon instructed Mr. F. G. Galbraith, of Lancaster County, Pennsylvania, to 

 examine the locality and to make drawings of the figures in question.f His 

 report and several communications from Dr. Stubbs are embodied in the 

 following accovint : — 



Bald Friar Rock is situated in the Lower Susquehanna, in Cecil 

 County, Maryland, and is about three-eighths of a mile distant from Bald 

 Friar, a station of the Columbia and Port Deposit Raih'oad. The rock 

 stands nearer the eastern than the western bank of the Susquehanna— here 

 three-quarters of a mile wide— and its distance from the mouth of the 

 river is nearlj^ twelve miles. It rises from a small island to a height of 

 eight feet and a few inches above low-water level, and can be reached by 

 land at very low water. Accoi'ding to Mr. Galbraith's measurement, the 

 i-ock was originally seventy-one feet long and ten feet wide; but only 

 sixteen feet of its eastern and seventeen of its western portion remain, the 



* The same plates illustrate now the "Second Geological Survey of Pennsylvania" (Geology of 

 Lancaster County, Harrisbuig, 1880). 



t Acknowledgments are also due to Dr. L. R. Kirk, of Rising Sun, Cecil County, Maryland, for a 

 very good drawing of Bald Friar Rock, sent by him to the Smithsonian Institution. It was of great 

 use as a medium of comparison.
