 The masonry of the dam is of local ! granite, set in British Portland cement mortar. The interior is of rubble set by
 hand with about forty per cent. of the 1 bulk in cement mortar, four of sand to
 one of cement. All the face work is of i coursed rack-faced ashlar, except the sluice Things, which are finely dressed. This was steam-crane and Italian ma sons work. There was great pressure ] at times to get a section completed be-
 fore the inevitable rise of the Nile, and
 as much as thirty-six hundred tons of 1 masonry was executed per day, chiefly
 at one point in the dam A triple line of railway and numerous trucks and To- comotives were provided to convey the | materials from quarries and stores to every part of the work The maximum
 number of men employed was eleven thousand, of whom q thousand were European masons and other skilled l men. One hundred and forty of the sluices are twenty three feet high by six feet six inches wide, and forty of them half the height; one hundred and thirty of the sluices are on the ''Stoney' principle with rollers, and the remain red move on sliding surfaces. The larger of the Stoney sluices weigh four teen tons, and are capable of being moved by hand under a head of water producing a pressure of four hundred and fifty tons against the sluice. There are five lock-gates, thirty-two feet wide and carrying in height up to sixty feet. They are of an entirely different type from ordinary folding locl-gates, being hung from the top on rollers, and nov ing like a sliding coach-house door.
 This arrangement was adopted for safe ty, as one billion tons of water are
 stored up above the lock gates, and l each of the two upper gates is made strong enough to hold up the water, as- suming the four other gates were de- stroyed.
 When the river is rising the sluices will all be open, and the red water will pass freely through, without depositing the fertilizing silt. After the flood, when the water has become clear and the discharge of the Nile has fallen to
 about two thousand tons per second, the gates without rollers will be closed.
 and then some of those with rollers; so that, between December and March the
 reservoir will be gradually filled. The reopening of the sluices will take place
 between May and July, according to the
 state of the Nile and the requirements
 of the crops. Between December and
 May when the reservoir is full, the is
 land of Philae will in places be slightly flooded. As the temples are founded partly on loose silt and sand, the satu-
 ration of the hitherto dry soil would
 cause settlements and no doubh injury to the ruins. To obviate this risk, all the important parts, including the we'll
 known Kiosk, or "Pharaoh's bed" have
 been either carried on steel girders or
 underpinned down to rock; or, failing
 that. to the present saturation level. It need hardly be said that, having regard to the shattered condition of the col umns and entablatures, the Inability of
 the stone, and the running sand foun- dation, the process of tnderpinnlng was
 an exceptionally difficult and anxious task.-New York Evening Post.
