Not illustrated. 1891 Excerpt: ...Generally the basins begin to fill in the first fortnight of August, and are emptied during October. It is estimated that the deposit of fertilizing mud left is 6.244 tons per acre, or a stratum of about 0.039 inch thick, if uniformly spread. The water exercises another important influence which contributes to the fertility of the soil, for after the water has run off the ground cracks into deep fissures, and is then subjected to a perfect aeration. The regulation of the basins is far more complicated than might at first seem, because the division of the water in the different basins has an important influence on the crops, and while it is easy enough to inundate the low lands, it is necessary sometimes to hold back the water for the high lands. Much depends on the rise of the Nile. If the rise be earlier than usual, the water penetrates too soon into the basins by infiltration or otherwise. Crops at lower points, which have been watered with great difficulty by wells or otherwise, are sub"merged before ripening or being gathered. If the rise be late, the sowing after the basins are emptied is similarly delayed, and the crops are exposed to the strong heat of the following spring. If the rise be not great enough, the high lands get no water or not enough, and are thrown out of the cultivation, or the basins get too little, to the damage of the subsequent crop. If the rise be too high, the dikes are threatened and require increased watching and care. If the rise last too long, there is still water in the feeding canal at the proper time for emptying the basins; these are emptied slowly, and the land stays wet too long. These difficulties of management, and the frequent connection of one basin system with another, render it impossible to leave the contro...
