C.E._ [2] _Engineering News._ [3] _Encyclopædia Britannica._ [4] The paper by Spring--in size it is a book--will repay perusal by engineers engaged on railway bridges over large shifting rivers.

[8] The regulator runs across the canal head; the under-sluices are a continuation of the weir, between the divide wall and the regulator. [9] See also Appendix B. [10] On Indian canals the term “regulation” is applied to the control of the discharge at the regulators or off-take works. [11] See also Appendix B. [12] _Irrigation Works_, CHAP. I., _Art. 4_.
