Anglo 119 --Egyptian] IRRIGATION > down in July -September as a torrential stream , irri gating during a normal season 50,000 acres of cotton growing lands at Tokar . The area under cultivation, however, depends entirely upon the extent and direc tion of the overflow , which is very variable .' In 1912 the area flooded was 44,000 acres,as against 54,000 in 1911 , the highest on record . Occasionally the river has broken away to the east, and the flood water has been lost on rough ground far outside the area allotted by the Government for cotton cultivation , with the result that the crop has been a failure . Attempts on a small scale to divert the flood into certain courses have been fairly successful ; but , until the Khor Baraka is scien tifically controlled (see p. 100 ), no greatimprovement can take place . The native in this district is anxious to use European ploughs and modern methods of culti vation , but it is not difficult to understand his aversion to any expenditure that would be fruitless should the flood water not irrigate his land .

The Khor Gash and the River Mareb are usually in flood between July 7 and September 15 , and the con ditions in Kassala as regards the uncertainty of the overflow are similar to those in Tokar . Engineering works are contemplated from which much improvement is expected Projected Irrigation Schemes . — The Anglo -Egyptian Sudan has witnessed the consummation of a number of engineering triumphs in connection with the conserva tion of water supplies since the country was released from a reign of terror less than twenty years ago and reopened to the world under British rule . There are now under consideration additional irrigation, storage, and reclamation schemes, having for their object either the provision of an abundant water supply to non irrigated districts, by means of a masonrystorage dam , or the reclamation of wide areas of land which at present are more or less useless. The most important of these are a scheme for the irrigation of the Gezira plain by means of the Blue Nile ; a project for impound a
