Rows of bricks are put down from one end to the other, with intervals between for the liquor to flow through to the tube.

On these rows a layer of stout reeds is first placed, and over them another layer composed of the leaves of these reeds.

On this bed the coarse reha earth is placed without being refined by the process described in the text above.

Some coarse common salt (kharee nimuck) is mixed up with the reha.

The tank is then filled with water, which filters slowly through the earth and passes out through the tube into pans, whence it is taken to another tank upon a wider terrace of cement, where it evaporates and leaves the sujjee deposited.
