SCENE IN THE TROPICAL EOREST NEAR VERA CRUZ AT AN EEEVATION OE 800 EEET 



"One can actually stand in a tropical jungle, where parrots, trogons, toucans, and other 

 equatorial birds are calling from the liana-draped trees, and look upward to forests of pines 

 and spruce, where crossbills, juncos, pine siskins, and evening grosbeaks are among the 

 common permanently resident species" (see text, pages 537 and 552).
