Annual report of the Bureau of ethnology to the secretary of the Smithsonian Institution .. . ormer purpose are made of any siliceous stone of convenient size andsuitable texture, from a coarse quartzite to a very fine close-grainedsandstone, according to the class of work to be done. The markingson them range from the narrow, sharp, incised lines due to shaping asmall ornament, to the broad grooves resulting from grinding an ax orcelt into form. Xearly all of those in museums are small specimensused for rubbing; but there are many large blocks in various localities, sometimes several feet square, marked and scored in every directionby grinding or sharpening the large implements on them. Among the polishers may be included a number of small pebbles ofvery hard siliceous stone, generally some form of quartz, which by thehigh polish show long use. The larger ones may have been used forrubbing skins in tanning, as they can easily be grasped in the hand.Very few have changed from their primitive form to a greater degreethan would naturally result from the wear upon them.
