Some curious pictures done by North American Indians have been found on rocks and stones, and on the stems of pine-trees in America, which furnish excellent examples of early picturing. Mr. Tylor, in his _Early History of Mankind_, gives engravings of several of these shadowy records of long-past events. One of these, which was found on the smoothed surface of a pine-tree, consists merely of a rude outline of two canoes, one surmounted by a bear with a peculiar tail and the other by a fish, and beyond these a quantity of shapes meant for a particular kind of fish. The entire picture records the successes of two chieftains named Copper-tail Bear and Cat-fish, in a fishing excursion. Another picture found on the surface of a rock near Lake Superior is more elaborate, and interests us by showing a new element in picturing, through which it was destined to grow into the condition of picture-writing. This more elaborate picture shows an arch with three suns in it--a tortoise, a man about to mount a horse, and several canoes, one surmounted by the image of a bird. All this tells that the chief called King-fisher made an expedition of three days across a lake, and arriving safely on land, mounted his horse. The new element introduced into this picture is symbolism, the same that transformed the homely system of tallies into the Scythian’s graceful living message to Darius. It shows the excess of thought over the power of expression, which will soon necessitate a new form. The tortoise is used as a symbol of dry land. The arch is, of course, the sky, and the three suns in it mean three days. The artist who devised these ways of expressing his thought was on the verge of picture-writing, which is the next stage in the upward progress of the art of recording events, and the stage at which some nations have terminated their efforts.
