perpendicularly: at others it shelves gently downwards, but in all directions it is quite inaccessible, except from above, and by the tunnel, down which we descended; and which will only admit one person at a time. Some shrubs and rock plants grow in the gallery, which in some degree shelter it from the south, to which, in other respects, it is entirely open. In the front, and to the right, as you stand with your back to the rock, it is exposed to no annoyance from assailants; but to the left, it is in some slight degree open to a fire of musquetry from neighbouring cliffs, which command it.

The term cavern does not exactly apply to it. It does not penetrate deep enough into the rock, and it is perfectly light in every part. The annexed sketch is an attempt to represent its appearance, and will help the reader to comprehend my description; but the point from whence it was taken, was not near enough for the purpose of an exact delineation.

We discovered evident marks of a fountain. The spot from which the water issued was still moist, and most probably there is a constant flow in less sultry months. But I could not satisfy myself that the gallery would afford an asylum for so many as 300 or 400 fugitives; nor did we find any relics of other days, though we searched diligently, and used the implements we brought with us in turning up and sounding the surface.
