CHARACTERISTICS OF THE ISTRIAN COAST
Istria is in great part a dry and stony land, but there are valleys with streams and woods. It slopes to the west and south with a tolerably continuous declivity, so that the base of the triangular peninsula is on the whole the highest part. Much of the vegetation is greyish, and the rocks also are generally a pale grey. It is divided into three districts, named, from, the prevailing colour of the ground, white, yellow, and red. The first is the stony portion, the grey limestone of the Karst; next the yellow sandstone formation which begins at Trieste and extends through middle Istria; and then the southern portion where the white limestone is underneath, and clay of a red ochreous colour occurs in streaks. Round Pisino and Pinguente and between them are fields, meadows, and even woods, with plenty of streams which burst from the sandstone, while limestone hills jut out here and there. Pisino lies on the edge of "yellow" Istria, and hills rise around it; on the south side is a hill of the red land; and the houses are on an outcrop of the white limestone. The Foiba runs along the junction of the two formations. Middle Istria undulates from about 1,200 ft. to 900 ft. above the sea, while Lower Istria is but 500 ft. The hills are lower and less steep, there is more cultivation, and the villages and towns look more prosperous.
