the hall. At the bottom of this chamber is a staircase L descending from the floor and without any breastwork to protect it, and therefore dangerous, as it goes down 6 feet, and is but about a foot and a half wide. This staircase is 12 feet long, and the passage M that is a continuation of it is hardly more than 4 feet high; at the entrance, and is nearly 20 feet long, so that one has to creep along it, bent double, assisted by one's hands.
"In this position it is absolutely impossible for one to turn round, so narrow is the passage. At this point a difficulty that is not anticipated arrests many a visitor. Water rises through the stones that form the floor and con- tributes to reduce the height of the gallery. If one elects to continue, there is no choice but to take a bath that reaches to one's middle. At a distance of nearly 7 feet comes a right angle, and the passage goes on for 6 feet, then turns to the left by an obtuse angle and pursues its course for 12 feet, then again turns to the right by another obtuse angle, and for 15 feet more one is still half under water, till N is reached, after which the level of the floor rises, as does also the ceiling; one is able to stand erect alongside of another person. In face of one, the wall is cut perpendicularly and seems abruptly to close the passage. However, at a few inches above the soil is a little opening D, formed like the mouth of an oven, and giving indications of a space beyond. In diameter it is about 1 foot 6 inches; by crawling through this hole, an achievement difficult to accomplish, as one cannot even use the elbows to work one's way forward, the explorer descends into a semicircular hall P whose vault is arched and is supported by two oval pillars, 7 feet high. The hall is 24 feet deep and 18 feet wide at the entrance, and is rounded at the further extremity. The soil in this chamber is encumbered with stones and rubbish thrown in from an opening at R, which seems to communicate with other subterranean excavations."
