As to all these ornaments in red jasper mentioned in this paper, comparison of the specimens forcibly suggests that they may be the work of one skilled artist. In the western pebble belt of Mississippi, which extends along the border of the Mississippi and Yazoo river bottoms southward from near Memphis to Natchez, and thence eastward through the counties in which these relics have been found, quartzite of almost every variety occurs, and chipped implements of almost every variety and color are common. The maker of these ornaments has passed by all other tints save red and brown. In the cylindrical and other carved forms that have been found there is a striking similarity both in design and workmanship. One will readily believe the perforation of these ornaments with small and accurately made drillings to have been the most difficult part of their manufacture. And yet in all the specimens seen the perforations have been in the _longest_ direction through the ornament. The total length of the borings in the set of thirty beads I have is twenty-eight inches. A lapidary not remarkably expert in the art of drilling these holes would probably have simplified his work by shorter borings, arranging the ornaments as pendants. Again, the rarity of any objects of carved or polished or perforated quartzite suggests a very limited manufacture even in the region under consideration. As to the means used in making these perforations, drills of stone are excluded from consideration on account of the smallness and length of the borings. There is one specimen in the collection of Dr. Joseph Jones of New Orleans, in which a boring has been began, evidently with a hollow tube as a drill, probably a joint of a reed fed with sand, as there is a core in the centre of the boring; but hollow drills as small as one-twelfth of an inch in diameter could scarcely have been used. Some of the specimens described by Dr. Rau show the beginning of the drilling process, apparently with a solid drill, fed with sand. We are forced to the conclusion that the drilling implement used must have been a needle of copper, or more probably of the hard outer wood of the Southern cane tipped with quartz, or fed with sand. The borings are about as true in direction and form as the best modern appliances could make them. It is worthy of note that these highly wrought jasper ornaments have been found in that portion of Mississippi once occupied by the Natchez, that these aboriginal people were more or less familiar with Mexican or Aztec art and customs, and that carved and polished workmanship in hard stones was not uncommon among the aborigines of Mexico and Central America.[68] SUGGESTIONS TO LOCAL HISTORIANS.
