At Zagazig the train stopped an hour or more for dinner, and there was a change of carriages for the passengers destined for Cairo. Zagazig is the junction of the lines for Cairo and Alexandria, and since the opening of the railway the town has become of considerable importance. A great deal of cotton is raised in the vicinity, and in some years not less than fifty thousand tons of that article are sent from the station. The country around here is very fertile, and is said to be the Goshen of the Bible. The ruins of the ancient town of Bubastis are about a mile from Zagazig, but they are so slight as to be unworthy a visit. Bubastis was an important place two thousand years ago, and was famous for a festival to which more than half a million pilgrims went every year.
For the remaining fifty-two miles from Zagazig to Cairo the route lay through a fertile country, and only occasional glimpses were afforded of the desert. Boats and barges were moving on the Canal, some of them carrying the local products of the country to Cairo or Ismailia, while others were laden with coal and other foreign importations which find a market among the Egyptians. The boys were interested in the processes of irrigating the lands, and eagerly listened to the Doctor's explanation of the matter. Before reaching Zagazig they had seen some men at work dipping water by means of buckets suspended from poles, and emptying it into basins formed by excavations on the banks; they were told that this apparatus for hoisting water was called a "shadoof," and had been in use from the most ancient days of Egypt.
"The simplest form of shadoof," said the Doctor, "is the one you are looking at. It consists of two posts of wood or sun-dried mud, supporting a horizontal bar, on which the pole suspending the bucket is balanced in the centre. A lump of mud on one end of the pole balances the weight of the bucket on the other, and enables the man who operates it to lift his burden with ease. The bucket is made of rushes woven so tightly as to hold water, and at the same time be as light as possible, and it is dipped and raised with great rapidity. Water is lifted from six to eight feet by the shadoof. If a higher elevation is needed, a second and even a third or a fourth may be used; on the upper part of the Nile I have seen half a dozen of them in operation on a series of steps, one above the other.
