were insufficient, and the work failed to accomplish the
object of the designer.
The total length of the Barrage is 3,312 feet, That
of the Diglis Barrage or weir at Worcester is 500 feet.
The work consists of two brick viaducts, founded on a
shallow mass of Beton, extending across the Bosetta
and Damietta branches, immediately below the point of
their divergence. The total length" across the Eosetta
Branch, including 61 arches and 2 lock-chambers, is
1,525 feet; and across the Damietta Branch, including
71 arches, 1,787 feet.
When the sluices fitted in the arched openings
were first closed, the water under pressure found its
way beneath the foundations, and, carrying sand with
it, undermined and endangered the whole structure.
Bractically, therefore, the Barrage has been of compa-
ratively little use except as a bridge for a roadway,
connecting the opposite banks of the river witb the
Delta,
The completion of the Barrage was one of the works
which the late Khedive most desired to have carried
out. By his instructions I made minute surveys and
studies, including observations to obtain the minimum
flow of the Nile, and also made borings to a consider-
able depth near the site of the Barrage. These borings
penetrated through the Nile deposit into the original
marine sand and gravel, and were of considerable interest
beyond the object for which they were taken. Even-
tually I drew up an exhaustive report, design, and
estimate for the whole work of rectification and com-
