line OF suction pipe the earth lOOsened

removal of 100000 yards of earth. The
power house will be equipped with

electric machinery by the General Elec

chinery in the power house will be
supported by strong concrete arches.
For the work of construction prepar-
atlons were made on scale that made
Tor rapid progress. A we'll built rail
road was constructed from Pee Dee
station, four miles away on the Sea-
board Air Line, right up to the west
ern line of the dam, over which ma
ter1al and supplies of all kinds have
been brought most cheaply and de-
llVered most conveniently. At its
nearest approach to the dam the road
runs onto a trestle so feet high and
