 THE CONDOR [ Vol. III Along the route whole canyon-sides are frequently found grown up to man- zanita and a tough, prickly brush, Ceanothus cordulatus, and the presence of these shrubs is usually indicative of a shallow, rocky soil. The deer-brush (Ceanolhus vdulimts), willowy in its nature and supporting fragrant white plumes, grows abundantly in places, and is replaced by willow thickets in the higher altitudes. This deer-brush is also a favorite feeding-ground of the numerous warblers and sparrows. Throughout the forest and in most open areas Chamwbalia foliolosa pHo'vo Ev c:. eARLOW. TYPICAL PATCH OF CHAMABATIA FOLIOLOSA IN TH[ grows luxuriantly. It is a pungent, rose-like shrub, known locally as "mountain misery" and affords secure nesting sites for Ppilo macztlaDts malls thurberi and Helninthophila rtbricapilla guilttrails. The grade from Place rvilleis gradual and the road for the most part passes through a beautiful timber-growth and approaches the American River at River- ton, whence it follows the river or its tributaries almost to the summit. After crossing the river, exposures of granite along the road are numerous and great patches and hillsides of (anolhus cordulatus,--a sharply-spiked shrub,--are much in evidence. This brush is an abomination to the collector, but frequently one may walk on top of the matted growth for quite a distance, but it is a thing to be avoided when possible. The most alluring portion of the Placerville-Tahoe road is encountered a few miles before reaching the summit, for here the mountain meadows begin, traver- sed by numerous brooks and bordered by a luxuriant growth of tamarack saplings.
