ground out in the sharpening of tools. There have been many dates of inscriptions, 
and each new generation has unserupulously run its lines over the pictures already 
made. Upon the best protected surfaces, as well as the most exposed, there are 
drawings dimmed beyond restoration and others distinct. The period during which 
the work accumulated was longer by far than the time which has passed since the 
last. Some fallen blocks cover etchings on the wall, and are themselves etched. 
Colors are preserved only where there is almost complete shelter from rain, In 
two places the holes worn in the rock by swaying branches impinge on etchings, 
but the trees themselves have disappeared. Some etchings are left high and dry by 
a diminishing talus (15 to 20 feet), but I saw none partly buried by an increasing 
talus (except in the case of the fallen block already mentioned). 
The painted circles are exceedingly accurate, and it seems incredible that they 
were made without the use of a radius. 
In the collection contributed by Mr. Gilbert there are at least fifteen 
series or groups of figures, most of which consist of the human form 
(from the simplest to the most complex style of drawing), animals, 
either singly or in long files—as if driven—bird tracks, human feet and 
hands, ete. There are also circles, parallel lines, and waving or un- 
dulating lines, spots, and other characters. 
Mr. Gilbert also reports the discovery, in 1883, of a great number of 
pictographs, chiefly in color, though some are only incised, in a canyon 
of the Book cliff containing Thompsows spring, about 4 miles north of 
Thompson’s station, on the Denver and Colorado Railroad, Utah. He 
has also turnished a collection of drawings of pictographs at Black 
rock spring, on Beaver creek, north of Milford, Utah. A number of 
fallen blocks of basalt at a low escarpment are filled with etchings upon 
the vertical faces. The characters generally are of an “ unintelligible” 
nature, though the human figure is drawn in complex forms. Foot- 
prints and circles abound. 
Mr. I. C. Russell, of the U. 8. Geological Survey, furnished rude 
drawings of pictographs at Black rock spring, Utah (see Fig. 1093). 
Mr. Gilbert Thompson also discovered pictographs at Fool creek canyon, 
Utah (see Fig. 1094). 
Mr. Vernon Bailey, in a letter dated January 18, 1889, reports that 
in the vicinity of St. George “all along the sandstone cliffs are strange 
figures like hieroglyphies and pictures of animals cut in the rocks, but 
now often worn dim.” 
Mr. George Pope, of Provo city, Utah county, in a letter, kindly gives 
an account of an inscription on a rock in a canyon at the mouth of 
Provo river, about 7 miles from the city named. There is no paint seen, 
the inscription being cut. A human hand is conspicuous, being cut 
(probably pecked) to a depth of at least one-third of an inch, and so 
with representations of animals. 
Dr. Rau (c) gives the design of a portion of a group carved on a cliff 
in the San Pete valley at the city of Manti, Utah, now reproduced as 
Fig. 51. He says: 
A line drawn horizontally through the middle of the parallel lines connecting the 
concentric circles would divide the figure into two halves, each bearing a close
