the lines were transferred to the muslin ; afler which it was sewed together 
in proper connection, and the lines made more permanent by repainting 
with diluted printers’ ink. Mr. E. B. Harden, of the State Geological Sur- 
vey, recently photographed asmall portion of the top surface of the rock ; 
but was unable to obtain a proper position for photographing the whole sur- 
face. To do this properly an elevated position would be necessary at some 
distance from the rock. This could be done by the aid of a small amount 
of lumber and tools, which we did not have at hand at the time of our 
visit. 
Plate 2 is a reduction from a tracing on muslin (natural size), showing 
the figures carved on the surface of a rock located on the east shore of the 
Monongahela river, a half mile below Geneva, in Fayette county, Penn- 
sylvania, The rock has a fairly even and smooth upper surface, falling 
slightly toward the water, and is an eroded portion of the Morgantown 
sandstone in place. A portion of this rock containing figures was removed. 
some years since, and used in constructing a building in Geneva. The 
figures thus removed I did not see. 
The execution of the carvings appears to be of the same character as 
that on the rock shown by Plate 1. The marked resemblance of many of 
the figures leads me to consider it of the same age and origin as the other 
sarved rocks in this region. At the time of my visit, in 1881, the upper 
portion of the rock rested only about four feet above low water, and I 
have since learned that the portion containing the figures copied has been 
rendered inaccessible by the back water, formed in the pool from the con- 
struction of Lock and Dam, No. 7, at a point nearly two miles farther 
down the river. 
Plate 8 is also a reduction from a tracing of a carved rock located in 
West Virginia, near the north side of the Evansville pike, six miles south- 
east of Morgantown. This is along the crest of an elevated ridge, com- 
manding a fine view of the surrounding country. The ridge on either 
side of this pike is strewn with numerous large blocks of sandstone, evi- 
dently detached from their native bed, and many of them present excel- 
lent surfaces for carving. But I only found two of them to contain any 
figures, out of a large number which I examined in the vicinity. 
The figures shown on this plate were all found on one rock, and are 
represented in their true position. They are incised or cut in the top suface, 
evidently in the same manner as the rocks already mentioned. The small 
pot-shaped holes, buffalo and bear tracks form a common feature of all 
these pictured rocks. Hach individual rock is however usually found to 
contain some figures not shown on others, Slight variations are also 
noticeable in the manner of representing certain animals and reptiles ; as 
for instance difference in posture. The rattlesnake is distinguishable by the 
line or bar which marks the termination of the body proper and shows the 
beginning of the rattles. The semi-circular figure on the left side of the 
plate forms, in my judgment, an interesting feature of this rock. It strikes 
me that this figure has been intended to represent a horse’s track or foot-
