In the Province of Tacna, the territory in dispute between Peru and Chile, a few traverse rivers flow down from the Andes to the sea; then a great stretch of waterless country until the oasis of Copiapo is reached. 1'notograpll Oy 1. 1'. Bcllecer YARETA, A CURIOUS PLANT OF THE ANDEAN DESERT This member of the celery family (Azarella yareta) grows in a dry, rocky country, at an altitude of about 15,ooo feet. It is green in color, highly resinous, makes an excellent fuel, burns like peat, with little flame and much smoke; gives a fair amount of heat, produces much ash, and throws out flames of many hues. In appearance the plant is altogether unlike its relatives, the celery and the parsnip.
