 surpassed, iKAvcvcr. liy the marvelous feather ornamentation of the 

 Mexicans and Peruvians, of which "glowing accounts are given by- 

 historians and of winch a few meager traces are found in tombs. 

 Much of the feather work of all nations is of the nature of embroidery 

 and will receive attention further on. A very clever device practiced 

 by the northwest coast tribes consists in the use of two woof strands 

 oi contrasting colors, one or the other being made to appear on the 

 surface, as the laattern demands. 



An example from a higher grade of art will be of value in this 

 connection. The ancient Peruvians resorted to many clever de- 

 vices for purposes of enrichment. An illustration of the use of ex- 

 tra-i-onstructional means to seciire desired ends are given in Figs. 

 ooi and ;j35. Threads constituting a supplemental warp and woof 

 are carried across the under side of a common piece of fabric, that 

 they may be brought up and woven in here and there to produce fig- 

 ures of contrasting color upon the right side. Fi.t;-. 'VM shows the

and shows the loose hanging, \inused portions of the auxiliary series. 

 In such woi'k, when the figures are niimerous and occupy a large part 

 of the surface, the fabric is really a double one, having a dual warp 

 and woof. Examples could be multiplied indefinitely, but it will 

 I'eadily be seen from what has been presented that the resxilts of these 

 extraordinary means cannot differ greatly from those legitimately 

 produced by the fundamental filaments alone.
