. Review of reviews and world's work. esist the pressure of any stream above system is practically the one used in theAssiout barrage. SEVEN THOUSAND FIVE HUNDRED DOLLARS A DAYIN WAGES. The Assiout dam is half a mile long and hasa navigation lock at the west side. The Iiverhas been coffer-dammed in sections, and a ma-sonry and concrete floor (40 feet below level ofhigh Nile) laid down as a foundation, 87 feetwide by 10 feet thick. On tliis floor the super-structure is built. At both up and down streamsides of this floor cast-iron sheet piles aie drivendown to a further depth of 13 feet, the joints ofwhich are hermetically sealed by cement grout,so that no percolations can get below the founda-tions. The barrage has 111 openings of about16 feet each, which will be supplied with ordi-naiy sluices. The navigation canal lock will be50 feet wide. This last year (1899) one-fourthof the whole work was done, and the wages paid(during June and July, for instance) were £1,500per day. .The outlay at the Assouan dam was even. greater, so that immense sums are spent amongthe natives of the country which the works areintended to benefit permanently. All the workdone at both reservoirs was left safely above thehighest water level till next season, and at As-siout no more coffer-dams will be needed Therewere 11,500 men employed at Assiout (and 8,500at Assouan), when the work had to be stopped,for the rising of the Nile. The walls at bothplaces are of stone and cement. The blocks ofstone were frequently so warm, owing to thefierce sunshine, that the mens hands were blis-tered in lifting them, and the heat of the placein June was 160° in the shade. But all hasgone on with scarcely an accident. There werea dozen cases of sunstroke, but only a very fewdeaths. It was remarked that those who dranktoo much liquid of any kind were most liableto it. The total cost of both reservoirs is estimatedat .$25,000,000. This will be met by an annualpayment, after the completion of the work
