The south-facing slopes of the mountains on the opposite side of tlie valley are almost devoid of trees (PL XI, phot. 1), though they contain some pine. They are covered with an herbaceous growth among which two low woody forms are abundant, a Berberis and a prostrate juniper. Juicc />. 141 INTENTIONAL SECOND EXPOSURE
