we cannot even conjecture. This bridge, close under the very walls of Zarû, [4] crossed the canal which separated the eastern frontier of Egypt from the desert regions of Arabia Petraea. A fortified enclosure protected this canal on the Asiatic side, as shown in the accompanying illustration (fig. 42). Fig 42.--Canal and bridge, Zarû, Karnak. Fig 42.--Canal and bridge, Zarû, Karnak.
The maintenance of public highways, which figures as so costly an item in the expenses of modern nations, played, therefore, but a very small part in the annual disbursements of the Pharaohs, who had only to provide for the due execution of three great branches of government works,--namely, storage, irrigation, mining and quarrying.

The taxation of ancient Egypt was levied in kind, and government servants were paid after the same system. To workmen, there were monthly distributions of corn, oil, and wine, wherewith to support their families; while from end to end of the social scale, each functionary, in exchange for his labour, received cattle, stuffs, manufactured goods, and certain quantities of copper or precious metals. Thus it became necessary that the treasury officials should have the command of vast storehouses for the safe keeping of the various goods collected under the head of taxation. These were classified and stored in separate quarters, each storehouse being surrounded by walls and guarded by vigilant keepers. Fig 43.--Cellar, with amphorae. Fig 43.--Cellar, with amphorae.
There was enormous stabling for cattle; there were cellars where the amphorae were piled in regular layers (fig. 43), or hung in rows upon the walls, each with the date written on the side of the jar; there were oven-shaped granaries where the corn was poured in through a trap at the top (fig. 44), and taken out through a trap at the bottom. At Thûkû, identified with Pithom by M. Naville,[5] the store-chambers (A) are rectangular and of different dimensions (fig. 45), originally divided by floors, and having no communication with each other. Here the corn had to be not only put in but taken out through the aperture at the top. Fig 44.--Granary. Fig 44.--Granary.
At the Ramesseum, Thebes, thousands of ostraka and jar-stoppers found upon the spot prove that the brick-built remains at the back of the temple were the cellars of the local deity. The ruins consist of a series of vaulted chambers, originally surmounted by a platform or terrace (fig. 46). At Philae, Ombos, Daphnae,[6] and most of the frontier towns of the Delta, there were magazines of this description, and many more will doubtless be discovered when made the object of serious exploration.

The irrigation system of Egypt is but little changed since the olden time. Fig 45.--Plan of Pithom. Fig 45.--Plan of Pithom.
Some new canals have been cut, and yet more have been silted up through the negligence of those in power; but the general scheme, and the methods employed, continue much the same, and demand but little engineering skill. Wherever I have investigated the remains of ancient canals, I have been unable to detect any traces of masonry at the weak points, or at the mouths, of these cuttings. They are mere excavated ditches, from twenty to sixty or seventy feet in width. The earth flung out during the work was thrown to right and left, forming irregular embankments from seven to fourteen feet in height.

The course of the ancient canals was generally straight: but that rule was not strictly observed, and enormous curves were often described in order to avoid even slight irregularities of surface. Dikes thrown up from the foot of the cliffs to the banks of the Nile divided the plain at intervals into a series of artificial basins, where the overflow formed back-waters at the time of inundation. These dikes are generally earth-works, though they are sometimes constructed of baked brick, as in the province of Girgeh. Very rarely are they built of hewn stone, like that great dike of Kosheish which was constructed by Mena in primaeval times, in order to divert the course of the Nile from the spot on which he founded Memphis.[7] The network of canals began near Silsilis and extended to the sea-board, without ever losing touch of the river, save at one spot near Beni Sûef, where it throws out a branch in the direction of the Fayûm. Here, through a narrow and sinuous gorge, deepened probably by the 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. 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.
