THE CANAL IS A TRIUMPH OF WILL OVER APATHY, OF WATER OVER SAND The historic "hyphen 'twixt West and East" was started by hand labor, but now several varieties of dredge areused tomaintain and deepen the waterway. The slender arm carries a sluiceway along which the sand and gravel sucked up are washed shoreward by water and dumpedinthe desert. Men arestationed along thesluice to keep the soupy mixture moving (see illustration, page 622). Originally 26 feet deep, much of the Canal today hasadepth of42feet, and allbutavery fewmodern leviathans may steam through it.
