In this way they make them scintillate and give to them a luster like the rays of the sun. 20. _Auh yn yehoatl motocayotia vitzitziltecpatl niman yuh yolli tlacati._ 20. And that which they call hummingbird silex (stone of a thousand colors) is (in color like) an animal of that nature. 21. _Miyec tlamantli ynic mocuicuiloua, iztac yoan xoxoctic yoan yuhquin tletl, anoço yuhqui citlali yoan yuhquin ayauhcoçamalotl._ 21.

The stone that they call round turquois is not very hard, so they have no need of emery to scrape, facet, smooth, or polish, for they apply to it the bamboo, then it receives its radiant luster and brilliancy. 24. _Auh yn yehoatl teoxihuitl ca amo cenca tlaquauac._ 24. The fine turquois is not very hard either. 25. _Çanno tepiton xalli ynic mopetlaua ynic moyectilia auh yn uel no yc motlanextilmaca motonameyomaca occentlamantli ytoca xiuhpetlaualoni._ 25. They polish it likewise with fine sand and they give to it a very brilliant luster and radiance by the method of another polisher, called the polisher of turquois. [Illustration: PL.
