ACROSS UNKNOWN SOUTH AMERICA 
a human foot on a scale smaller than nature, they limited 
themselves to carving two lines at a wide angle, to form 
the heel, and five dots to represent the toes. 
The most wonderful of those rock carvings were the 
footprints of the jaguar (onpa), reproduced with such 
perfection that it seemed almost as if they had been left 
there by the animal itself. Not so happy were the repre¬ 
sentations of human heads, one, evidently of an Indian 
chief, with an aureole of feathers, showing a painfully 
distorted vision on the part of the artist. The eyes were 
formed by two circles in poor alignment, the nose by a 
vertical line, and the mouth, not under but by the side of 
the nose, represented by two concentric curves. 
A figure in a sitting posture was interesting enough, 
like a T upside down, with a globe for a head and a cross¬ 
bar for arms. The hands had three fingers each, but there 
were only two toes to each foot. 
It was interesting to note how the sculptors of those 
images caught, in a rudimentary way, the character of 
the subjects represented. This was chiefly remarkable 
in the footprints of birds and other animals, such as deer. 
They seemed particularly fond of representing deer- 
horns, sometimes with double lines at an angle. That 
was possibly to commemorate hunting expeditions. A 
frequent subject of decoration was a crude representation 
of the female organ; and one, a magnified resemblance, 
angularly drawn, of an Indian male organ garbed in its 
typical decoration. 
The face of the rock was absolutely covered with 
drawings, many being mere reproductions of the same 
design. Some were so rudimentary that they were abso¬ 
lutely impossible to identify. One fact was certain, that 
those carvings had been made by men who were trackers 
by nature and who observed chiefly what they noticed on 
the ground, instead of around and above them. Thus, 
there were no representations whatever of foliage or trees,
