5.—Walls and Facings.

Walls of loose stones are now quite common along the sea side of the villages for keeping pigs from getting to the cultivations.

Stone walls were also extensively used in the terraces in the taro cultivations. The sides of the terraces on the hill side of the slope were excavated, but the sides on the down slope had to be built up with facings of stone to support the earth. The sides were also built up a little higher than the terrace surface in order to hold the water when the terrace was submerged with water from the irrigation channels.
