Laying out checks

13. The field Is divided Into plots.

Often the ground of the plots slopes. With sloping ground, it is impossible to have the same depth of water everywhere. To get the same depth of water everywhere, you must have ground that has no slope.

To get ground without slope, divide your plots Into checks.
Checks are made by building bunds.
These are small earth embankments, each 30 centimetres high and 40 centimetres wide.
If the slope is steep, make many small checks.
Pack the earth of the bunds down firmly, so that you can walk on them.
Build the bunds so that they follow the contour lines.
