Fig. 1. San Jacinto Peak, in back center, as viewed from Tahquitz 

 Peak. The steep declivity in foreground rises from Strawberry Val- 

 ley; at extreme right center is the edge of Tahquitz Valley. The patches 

 of brush in the right foreground are chiefly composed of chinquapin 

 (Castanopsis sempervirens) and manzanita (Arctostaphylos patula). Here 

 is the summer home of Passerella iliaca stephensi and the forage ground 

 of Eutamias speciosus, both being animals of the upper Transition zone. 

 The trees on the ridge at the right are chiefly Jeffrey pines, those on 

 the higher distant slopes are lodgepole and limber pines. The latter two 

 are purely Boreal elements. 



Fig. 2. Southeast wall of Strawberry Valley, showing lower Transi- 

 tion forest of black oak, incense cedar, yellow pine, ami sugar pine. 

 with silver firs of upper Transition on the higher portions of the slope. 

 From this wooded slope were heard the notes of Stria; o. occidentalis; 

 other characteristic birds were: Piranga ludovicicma, Jfuttallornis borealis, 

 and Xenopicus a. gravirostris.
