On the west side of this mosaic floor, where it joins the wall of the main building, there is a threshold of a single stone, 9 feet 6 inches long, with a step 6 feet 9 inches in the clear. This is considerably wider, it will be seen, than the steps, and even the entrance of the church. Several patches of mosaic pavement have been found, but in one place two or three square yards have been preserved, enough to show that the work was extremely beautiful. The colored tracings resemble those in the church on the Mount of Olives, and on one side are the large Greek letters [Theta][epsilon][omicron][nu]. North of this mosaic floor, and of the main building which joins it, and running alongside of both, there is a watercourse or channel cut in the solid rock, which has been leveled to accommodate the buildings above. This can be traced in an east and west line for a distance of 37 feet; it is 2 feet 3 inches deep, 20 inches wide at the top and 12 at the bottom. From about the middle of the mosaic floor this channel turns a right angle and runs 20 feet or more to the north; it is possible that it led _from_ the north, and at the point indicated turned a right angle and ran to the west. Piles of stones and _debris_ prevent us at present from deciding as to the length of the channel or where it comes from. In the bank of _debris_, which rises on the east side of the mosaic floor to a height of 20 feet, there is, about 6 feet above the floor, a watercourse formed of cement, running north and south at right angles to the line of the church and the other buildings, which must have belonged to a much later period. In fact--and this is an interesting circumstance--the mosaic pavement appears to extend under and beyond this canal and the mass of _debris_ which is yet to be removed. In the northwest corner of the room, where the mosaic floor is found, very near the angle (already mentioned) of the rock-cut channel, there is a tomb about 6 feet below the surface or level of the floor. The tomb is 10 feet long and 9 feet wide, and is entered by a doorway 26 inches wide, which is well built, and in the sides of which are grooves for a door to slide up and down. On the wall of the tomb at the east end there is a raised Greek cross, 22 inches long and 13 inches wide. One cannot stand erect in its highest part, but it is to be considered that the loculi are two-thirds full of _debris_, composed chiefly of decayed bones and bits of glass. Those in charge of the excavations have not, up to the present time, allowed the tombs to be cleared out. The loculi are 2 feet in depth.
