THE SHILOH TUNNEL.
Evidence exists that a work similar to the famous Simplon tunnel, but on a smaller scale, was executed some twenty-four centuries ago. Owing to the bad state of the water supply of Jerusalem, the king ordered a reservoir to be made at the gates of the city, to which water was to be brought from various springs. The Shiloh tunnel, by means of which water was brought down front a source to the east of Jerusalem and poured into the pool of Siloant, was 1,080 ft. long and in a straight line. It has been learned that work was begun at both ends of the tunnel and the direction altered a number of times. The floor of the tunnel is finished with great care. The width vanes trom 1.0 to 3 ft., and the height from 8 to o ft. There is much speculation as to how these engineers gauged their direction so well as to be able to recognise and connect errors in alignment.
