The deep engravings, on the other hand, consist not of a single figure but of a greater or less number of rude drawings. * * These depict the human form, monkeys, snakes, and other animals, and also very simple combinations of two or three straight or curved lines in a pattern, and occasionally more elaborate combinations. The individual figures are small, averaging from twelve to eighteen inches in height, but a considerable number are generally represented in a group. Some of the best examples of this latter kind are at Warrapoota cataracts, about six days’ journey up the Essequibo. * * * The commonest figures at Warrapoota are figures of men or perhaps sometimes monkeys. These are very simple, and generally consist of one straight line, representing the trunk, crossed by two straight lines at right angles to the body line: one, about two-thirds of the distance from the top, represents the two arms as far as the elbows, where upward lines represent the lower part of the arms; the other, which is at the lower end, represents the two legs as far as the knees, from which point, downward lines represent the lower part of the legs. A round dot, or a small circle, at the top of the trunk-line, forms the head; and there are a few radiating lines where the fingers, a few more where the toes, should be. Occasionally the trunk-line is produced downwards as if to represent a long tail. Perhaps the tailless figures represent men, the tailed monkeys. In a few cases the trunk, instead of being indicated by one straight line, is formed by two curved lines, representing the rounded outlines of the body; and the body, thus formed, is bisected, by a row of dots, almost invariably nine in number, which seem to represent vertebræ. Most of the other figures at Warrapoota are very simple combinations of two, three, or four straight lines similar to the so-called ‘Greek meander pattern,’ which is of such widespread occurrence. Combinations of curved lines and simple spiral lines also frequently occur. Many of these combinations closely resemble the figures which the Indians of the present day paint on their faces and naked bodies. The resemblance is, however, not so great but that it may be merely due to the fact that the figures are just such simple combinations of lines which would occur independently to the rock-engravers and to the body-painters as to all other untaught designers.
