The figures are represented in their present state in outline by a continuous indentation or groove from 1 to 1-1/2 inches broad by half an inch to 1 inch in depth. Some are single subjects scattered promiscuously over the surface; others form small groups, illustrating compound subjects, but all appear to have been executed about one and the same time. * * *
An advance on the other sculptures existing at this place seems to be made in the originals of the designs _a_ and _b_, from the fact that an attempt was apparently made to represent a compound idea in the form of a single combat between two warriors. The figures are quite contiguous to one another. The individual marked _a_ seems to be holding in his right hand a body similar to that represented as _c_, and the position in which it is held would lend color to the belief in its shield-like nature. In the opposite hand are a bundle of rods which have been suggested to be spears, and this explanation for the want of a better may be accepted. On the other hand, we are confronted with the fact that these weapons of offense and defense are held in the wrong hands, unless the holder be regarded as sinistral; otherwise it must be conceived that the warrior’s back is presented to the observer, which is contrary to the other evidence existing in the carving. The opponent, marked as _b_, with legs astride and arms outstretched much in the position of an aboriginal when throwing the boomerang, is equally definitive. I conceive it quite possible that the position of the boomerang close to the right hand conveys the idea that this man has just thrown the missile at the subject of _a_, allowing, of course, for the want of a knowledge of perspective on the part of the aboriginal artist. * *
In several other figures the head is a mere rounded outline, but in _b_ it is presented with a rather bird-like appearance. Another peculiarity is the great angularity given to the kneecap: this is visible both in _a_ and _b_. It is further exemplified in the elbow of the left arms of both _a_ and _b_.
The term “Oceanica” is used here without geographic precision, to include several islands not mentioned in other sections of the present work, in different parts of the globe, where specially interesting petroglyphs have been found and made known in publications. Although more such localities are known than are now mentioned, the pictographs from them are not of sufficient importance to justify description or illustration, but it may be remarked that they show the universality of the pictographic practice.
