hand of man, it passes the rocky barrier which divides that low-lying province from the valley of the Nile, and thence expands into a fanlike ramification of innumerable channels. Having thus irrigated the district, the waters flow out again; those nearest the Nile returning by the same way that they flowed in, while the rest form a series of lakes, the largest of which is known as the Birket el Kûrûn. If we are to believe Herodotus, the work was not so simply done. A king, named Moeris, desired to create a reservoir in the Fayûm which should neutralise the evil effects of insufficient or superabundant inundations. This reservoir was named, after him, Lake Moeris. If the supply fell below the average, then the stored waters were let loose, and Lower Egypt and the Western Delta were flooded to the needful height. If next year the inundation came down in too great force, Lake Moeris received and stored the surplus till such time as the waters began to subside. Two pyramids, each surmounted by a sitting colossus, one representing the king and the other his queen, were erected in the midst of the lake. Such is the tale told by Herodotus, and it is a tale which has considerably embarrassed our modern engineers and topographers. How, in fact, was it possible to find in the Fayûm a site which could have contained a basin measuring at least ninety miles in circumference? Linant supposed "Lake Moeris" to have extended over the whole of the low-lying land which skirts the Libyan cliffs between Illahûn and Medinet el Fayûm; but recent explorations have proved that the dikes by which this pretended reservoir was bounded are modern works, erected probably within the last two hundred years. Major Brown has lately shown that the nucleus of "Lake Moeris" was the Birket el Kûrûn.[8] This was known to the Egyptians as
Miri, Mi-ûri, the Great Lake, whence the Greeks derived their
Moiris a name extended also to the inundation of the Fayûm. If Herodotus did actually visit this province, it was probably in summer, at the time of the high Nile, when the whole district presents the appearance of an inland sea. What he took for the shores of this lake were the embankments which divided it into basins and acted as highways between the various towns. His narrative, repeated by the classic authors, has been accepted by the moderns; and Egypt, neither accepting nor rejecting it, was gratified long after date with the reputation of a gigantic work which would in truth have been the glory of her civil engineers, if it had ever existed. I do not believe that "Lake Moeris" ever did exist.
Fig 47.--Dike at Wady Gerraweh. The only works of the kind which the Egyptians undertook were much less pretentious. These consist of stone-built dams erected at the mouths of many of those lateral ravines, or wadys, which lead down from the mountain ranges into the valley of the Nile. One of the most important among them was pointed out, in 1885, by Dr. Schweinfurth, at a distance of about six miles and a half from the Baths of Helwan, at the mouth of the Wady Gerraweh (fig. 47). It answered two purposes, firstly, as a means of storing the water of the inundation for the use of the workmen in the neighbouring quarries; and, secondly, as a barrier to break the force of the torrents which rush down from the desert after the heavy rains of springtime and winter. The ravine measures about 240 feet in width, the sides being on an average from 40 to 50 feet in height. The dam, which is 143 feet in thickness, consists of three layers of material; at the bottom, a bed of clay and rubble; next, a piled mass of limestone blocks (A); lastly, a wall of cut stone built in retreating stages, like an enormous flight of steps (B). Thirty-two of the original thirty-five stages are yet
in situ, and about one-fourth part of the dam remains piled up against the sides of the ravine to right and left; but the middle part has been swept away by the force of the torrent (fig. 48). A similar dike transformed the end of Wady Genneh into a little lake which supplied the Sinaitic miners with water.

Most of the localities from which the Egyptians derived their metals and choicest materials in hard stone, were difficult of access, and would have been useless had roads not been made, and works of this kind carried out, so as to make life somewhat less insupportable there.
In order to reach the diorite and grey granite quarries of the Hammamat Valley, the Pharaohs caused a series of rock-cut cisterns to be constructed along the line of route. Some few insignificant springs, skilfully conducted into these reservoirs, made it possible to plant workmen's villages in the neighbourhood of the quarries, and also near the emerald mines on the borders of the Red Sea. Hundreds of hired labourers, slaves, and condemned criminals here led a wretched existence under the rule of some eight or ten overseers, and the brutal surveillance of a company of Libyan or negro mercenary troops. The least political disturbance in Egypt, an unsuccessful campaign, or any untoward incident of a troubled reign, sufficed to break up the precarious stability of these remote establishments. The Bedawîn at once attacked the colony; the workmen deserted; the guards, weary of exile, hastened back to the valley of the Nile, and all was at a standstill.
The choicest materials, as diorite, basalt, black granite, porphyry, and red and yellow breccia, which are only found in the desert, were rarely used for architectural purposes. In order to procure them, it was necessary to organise regular expeditions of soldiers and workmen; therefore they were reserved for sarcophagi and important works of art. Those quarries which supplied building materials for temples and funerary monuments, such as limestone, sandstone, alabaster, and red granite, were all found in the Nile valley, and were, therefore, easy of access. When the vein which it was intended to work traversed the lower strata of the rock, the miners excavated chambers and passages, which were often prolonged to a considerable distance. Square pillars, left standing at intervals, supported the superincumbent mass, while tablets sculptured in the most conspicuous places commemorated the kings and engineers who began or continued the work. Several exhausted or abandoned quarries have been transformed into votive chapels; as, for instance, the Speos Artemidos, which was consecrated by Hatshepsut, Thothmes III. and Seti I. to the local goddess Pakhet.[9]
The most important limestone quarries are at Tûrah and Massarah, nearly opposite Memphis. This stone lends itself admirably to the most delicate touches of the chisel, hardens when exposed to the air, and acquires a creamy tone most restful to the eye. Hence it was much in request by architects and sculptors. The most extensive sandstone formations are at Silsilis (fig. 49). Here the cliffs were quarried from above, and under the open sky. Fig 49.--Quarries of Silsilis. Clean cut and absolutely vertical, they rise to a height of from forty to fifty feet, sometimes presenting a smooth surface from top to bottom, and sometimes cut in stages accessible by means of steps scarcely large enough for one man at a time. The walls of these cuttings are covered with parallel striae, sometimes horizontal, sometimes slanting to the left, and sometimes to the right, so forming lines of serried chevrons framed, as it were, between grooves an inch, or an inch and a half, in width, by nine or ten feet in length.

These are the scars left upon the surface by the tools of the ancient workmen, and they show the method employed in detaching the blocks. The size was outlined in red ink, and this outline sometimes indicated the form which the stone was to take in the projected building. The members of the French Commission, when they visited the quarries of Gebel Abûfeydeh, copied the diagrams and squared designs of several capitals, one being of the campaniform pattern, and others prepared for the Hathor-head pattern (fig. 50).[10] The outline made, the vertical faces of the block were divided by means of a long iron chisel, which was driven in perpendicularly or obliquely by heavy blows of the mallet. In order to detach the horizontal faces, they made use of wooden or bronze wedges, inserted the way of the natural strata of the stone. Very frequently the stone was roughly blocked out before being actually extracted from the bed. Thus at Syene (Asûan) we see a couchant obelisk of granite, the under side of which is one with the rock itself; and at Tehneh there are drums of columns but half disengaged.
