The valley of the Gihon becomes deeper as it passes eastward to where it meets the Kedron. Below the second pool it takes the name of the Valley of the Son of Hinnom or Tophet. It was formerly used for many unclean purposes--some of the most abhorrent kinds of idolatrous worship was once practised here--the burning of children to Moloch, Jer. vii. 31. The valley appears to have been much contracted by the great quantity of rubbish of all kinds which has been thrown into it from the city. A road from the Jaffa gate passes down the valley, dividing at the lower pool. One part passes to the south side, and winding along the top of the bank for some distance, crosses the plain southward to Bethlehem. The other winds down the valley until it reaches the bottom--then along the valley until it meets the one from the valley of Kedron, following the course of the united valleys towards the Dead Sea. On the south side of the valley of Hinnom, and near its junction with Kedron, is the potter's field. It is a small parcel of ground near the top of the bank with an old ruined house on it. There was a small level spot thirty feet below the top of the bank, at the bottom of a thick stratum of horizontal rock. Walls have been made enclosing a part of this--the face of the rock forming the south wall of the building. The roof, which is flat, is on a level with the top of the bank; and in it are a number of holes, through which they used to throw the dead bodies. It is not used now as a place of interment, and is fast going to ruin, part of the walls having fallen in. All along the south side of the valley are to be seen old tombs cut in the rock--some are of considerable size, having several rooms--some are so large as to be used by mules, donkeys, and other animals, as places of refuge from the noonday heat of the sun. At the junction of the valley of Hinnom with that of the Kedron, which is nearly at right angles--the Hinnom running nearly east and the Kedron nearly west--there is a level space of several acres, laid out in gardens, and well set with trees. These gardens and trees continue up the valley of the Kedron, which is wider than that of the Hinnom, for some distance; this rich and beautiful-looking spot, watered by the fountain of Siloam, is called the _King's Dale_. These valleys have all steep, high banks. To the east of the Kedron lies Mount Olivet, which runs north and south, and is separated from the hill on which the city stands only by the deep, narrow valley of the Kedron.
