 right distance apart to admit the sliding board or gate to pass up and down 

 between them. These gates are about a foot wide in small work, and 

 from 2 to 4 feet wide if a larger stream of water is available. Where 

 cross levees are used to make smaller checks more gates are placed in the 

 highest levee, so as to all'ow^ the water to flow down in one direction and 

 then in another until ail the series have been filled. 



In Victoria it will be the better plan to have a head supply channel 

 crossing the field from which the checks on either side can be filled. Boxes 

 should be placed in the banks lof the levees to drain the water from the upper 

 check into the one next lower, after the soil has been sufiicientlv moistened.

rectangular checks differs from contour checks by having the levees in 



straight lines and the checked areas nearly uniform in size. It is not 



suited to the conditions in Victoria because it requires more grading of
