different drainage furrows, which are sometimes 6 feet deep and full of pebbles. Kuh-i-Jandak becomes more distinct, and on the north side of its upper part, turned towards the salt desert, some snow lies.
A furrow with clearly marked terraces runs out of a large valley to the right, and swings suddenly round to the north, running on to Jandak. Here also begins the kanat which supplies Jandak with water, and we follow closely its line of earth-heaps. They become smaller, and at last the water runs out of its subterranean conduit and flows on in a straight surface channel, sunk in an embankment of earth, so that it lies 3 feet above the level ground around. It is protected from evaporation by a belt, a foot broad, of grass and reeds which on both sides form a shady screen above the water. Beside the canal an underground mill (seng-asiab) is constructed ; a small staircase leads down into the cave, where a horizontal millstone is set in movement by the canal water. Two mulberry trees grow outside a court with a wall and tower —an unusual sight. A little later we pitch our tents in the southern outskirts of Jandak, a town as yellow and dreary as the country round about.
