These locks, as shownin fig. 6, have three .The central or main one is60 feet wide and 390 feet long, and will be furnished withtwo pairs of- gates at each end, pointing in opposite di/eo- CANAL 789 tions, and one pair in the centre.

In constructing the canal,which is (1876) now far advancedtowards completion, the cuttings were first begun. Thematerial proceeding from these cuttings was deposited so asto form two banks 443 feet apart, through the lakes oneach side of the main canal, as shown by the hard lines onthe plan, and also to form the banks of the branch canalson either side. The total length of these banks is S&ymiles. The nucleus of the bank is formed of sand with acoating of clay,, and protected during its progress withfascines; and when the banks are far enough advanced, thedeep channel for the canal is excavated by dredging. Thecross-section of the canal and banks through these meers orlakes is shown in fig. 7.
