174 PICTURE-WRITING OF THE AMERICAN INDIANS. 
On some rocks are representations of cattle, horses, reindeer, turtles, ostriches, 
and camels, the latter showing that in earlier times these people were acquainted 
with more southern climes. The greatest number and the largest and most compli- 
cated in detail of the tracings oceur, especially in the present Sweden, in Bohuslin, 
“the ancient Viken of the Sagas,” on the coast of the peninsula washed by the Catte- 
gat. They are also found in Norway, especially in Smaalenene, a province contigu- 
ous to that of Bohusliin, but become more scarce in the north, though found on the 
Trondhjem fjord. 
Fig. 137 is a copy of a petroglyph in Tanum parish, Bohuslin, Swe- 
den. The large figure is doubtless a champion or commander, the ex- 
aggerated size of which is to be noted in connection with that of the

Fig. 137.—Petroglyph in Bohuslan, Sweden. 
Zulu chiefs in Fig. 142, infra, from South Africa, and Fig. 1024, infra, 
from North America. There are numerous small holes and footprints 
between the chief and the attacking force. Height, 20 feet; width, 15 
feet. 
In Bohuslin the tracings are cut in the quartz, which is the geological formation 
of the coast. They are mostly upon slightly inclined rocks, which are generally 200 
or 300 feet or more above the present level of the sea, and which have been polished 
by the action of the ice. The width of the lines in the same representation varies from” 
1 to 2 inches and even more, and their depth is often only a third or fourth of an 
inch, and at times so shallow as to be barely perceptible. Those tracings, which 
have for hundreds, perhaps for thousands, of years been laid bare to the ravages of 
the northern climate, are now most difficult to decipher, while those which have 
been protected by earth are as fresh as if they had been cut to-day. Many seem to
