A shepherd camp their edge. The mass of Elburz across the valley seemed smaller now than under its winter snows, but a tiny semi- glacier still hung in each of its two pockets. On Mount Sat, to the east of it, snow still lay. A line of white strata running in a jagged zig-zag across the uninhabited eastern landscape is called Abraham's Path, where, travelling quite unhistorically with his ewes before him, their milky dripping udders are said to have left this enduring sign. Here the air was thin, the distances were clearer: we were truly in the hills at last. In a hollow strewn with boulders, where two or three springs bubbled out of the ground, we found a master of flocks and his people, living in summer huts whose low roofs were made of poplars from Narrnirud in the valley below, covered with faggots and turf, and whose wall was the hillside itself, which pushed thick shelves of rock into the rooms. Three walls of stones loosely piled were built out to make each dwelling: a boulder made the table, a bit of flat earth the hearth: and little stone pens surrounded the huts, filled with trodden sheep dung whose acrid smell, mingled with that of smoke from household fires, comes not unpleasantly to the nostril of a mountaineer. These people lived at Verkh through the winter, and on the slopes of Chala in the spring. Here to their summer pastures they brought only the bare necessities of life, and chief among them the tall four-handled jars of earthenware in which milk, gently tilted from side to side, is turned with time and patience into butter. " Dug," or curds, were drying in sacks on the roofs, which, being not more than about four feet off the ground, were used as tables from the outside. Dogs and children and cooking-pots surrounded the little camp, where everyone stopped, their various activities suspended, to look with suspicious surprise at our approach. [281]
