Hey! Run the level across this bit will ya! I need to work out deep a
trench to dig!

The Egyptians didn't have garden hose. They dug trenches, filled them
with water, and measured off the water surface. For work too high above
ground level to conveniently reference off water in a surface trench, they
erected troughs or connected two basins with clay pipe.
