Pigs. 121-122. Green 

 Snake (Liopettis ver- 

 nal is) , righ t-side-ti p 

 (Fig. 121), and up-side- 

 down (Fig. 122). (The 

 normally placed one — 

 Fig. 1 2 1 — however, is 

 very poorly lighted for 

 'obliteration',) 



Fig. 128. The surroundings of this Rattlesnake have been made wholly by copying the snake's own color- 'values,' — by perceiving what 

 scene he represents, and using each one of his 'notes' for the right detail of the scene. The result is an astonishingly true rendering of 

 t he stones he frequents. 



This picture, like several others in the book, shows that animals' normal environments may be exactly deciphered from their coloration.
