The Human Figure: and to these I append The Frog, which is found in Arizona only, and although carved in shell does not appear to have been used as a pendant, as no perforations are visible. Within the United States ancient tablets containing engraved designs are apparently confined to the Atlantic slope, and are not found to any extent beyond the limits of the district occupied by the stone-grave peoples. Early explorers along the Atlantic coast mention the use of engraved gorgets by a number of tribes. Modern examples may be found occasionally among the Indians of the northwest coast as well as upon the islands of the central Pacific. THE CROSS. The discoverers and early explorers of the New World were filled with surprise when they beheld their own sacred emblem, the cross, mingling with the pagan devices of the western barbarian. Writers have speculated in vain--the mystery yet remains unsolved. Attempts to connect the use of the cross by prehistoric Americans with its use in the East have signally failed, and we are compelled to look on its occurrence here as one of those strange coincidences so often found in the practices of peoples totally foreign to each other. If written history does not establish beyond a doubt the fact that the cross had a place in our aboriginal symbolism, we have but to turn to the pages of the great archæologic record, where we find that it occupies a place in ancient American art so intimately interwoven with conceptions peculiar to the continent that it cannot be separated from them. It is found associated with other prehistoric remains throughout nearly the entire length and breadth of America.
