VII. Plant-life of Svanetia, Trans-Caucasus Face p. 153 witness to an intensely hot midday in August. Precipitation is 600-700 cm. annually. Irrigation is generally practised. It is at Tavrari that one first realises how conspicuous a feature of the Svanetian forests is Populus tremula. It usually occurs scattered among ever- green trees, its tall pale grey trunk and crown of delicate green foliage standmg out in strong contrast to the dark colour of the conifers, though it may often form almost pure stands (PI. XIV, phot. 1). The night, if not several days, should be spent at Tavrari, food permittmg; the Soviet Base, housed in the school, supplies nothing except roof and mattress. One may proceed to the nearby and larger village of Lahamuh, where living conditions are but little better, though the village is very pic- turesque. The journey of 25 km. from Tavrari to Betcho, easily made ma day, is one of magnificent scenery with Picea-Abies forests covermg the northern slopes of the Ingur Valley throughout the way. The large fern Struthiopteris with its interesting fruiting frond, later to be met with in abundance, borders the trail to Betcho, with an occasional specimen of Vincetoxicum officinale. At Betcho, a stay for the mght or longer should be made, if for no oth
