In the region of domestic policy this strange combination of barbarism and genius proved that he retained the commercial instincts of the tobacco-seller as well as the far-reaching ideas and the drastic methods of the despot. He perceived the advantages which would accrue from the cultivation of cotton and the sugar-cane, hitherto unknown in Egypt. These crops are impossible under a system of basin irrigation; for though they require to be watered all through the summer, they would be ruined by complete inundation, and the shallow flood canals are well above the summer level of the river. But difficulties were nothing to Mehemet Ali. The corvée was called out, and the unfortunate fellaheen were set to work to dig new canals and reconstruct the existing water-ways in the Delta, so as to render them capable of conveying water during the period of low Nile. At the same time the dykes along the banks of the Nile and the canals were very much strengthened, so as to keep out the flood; the old basin dykes were obliterated, and arrangements made for irrigating the land from the new canals. Of course, perennial irrigation in itself had always existed in Egypt. It would have been indeed strange if the principle applied by anybody who daily waters a window-box had not occurred to the Egyptians. The Nile berms were often enclosed to protect them from inundation, and watered directly from the river all the year round, while within the basins themselves considerable tracts were irrigated from wells. But never before had special canals been provided by Government for perennial irrigation. The advantages of perennial irrigation are that crops like cotton and sugar can be grown, which would otherwise be impossible, and that two, or even three crops, can be produced in a year, instead of only one. The land is therefore increased in value, but, on the other hand, there are serious objections. First of all, the land is deprived of the full benefit derived from the annual renewal of the soil by the silt deposit. Agriculture becomes a much more intricate and difficult process; the exhausted soil has to be constantly refreshed and stimulated by dressings and manures. The basin irrigator makes less profits, but he has less risk and less anxiety; he can only ride a donkey, while the perennial irrigator can ride a horse. But behind the horseman sits black Care. A low summer supply means to him the waste of many weeks’ labour and much expenditure in preparing and sowing his fields; the basin irrigator does nothing till the flood is over, and should the inundation not cover a part of his land, it merely means that that part lies fallow for another year, and suffers no deterioration. A breach in the dykes during the flood is inconvenient to the one, no doubt, but fatal to the other, for it means the ruin of his growing cotton or sugar. And under perennial irrigation it is much more likely to occur, for the basins act as
