This is a much wiser method of procedure than to have constructed six or seven canals and find that only five were required to do the work. Lateral Canals. The next step in any plan of reclamation is to provide means for promptly removing the excess of water that falls directly on the Everglades. This can be done on practically all the area by gravity drainage. In the southern part some' of the ponds and depressions may be so low as to require pumping, but these are very small and the land of doubtful value when;1 drained. Just how much local precipitation L will have to be removed from this area by drain-, ' age is another matter about which engineers do not agree, since no other body of land like the Everglades has been reclaimed. Eesults obtained by actual experience are lacking. Conclusions based solely on theory are often disappointing, so experience must be the final arbiter in determining the quantity that must be removed. The main arteries now being built for con-; trolling the overflow from the lake increase in: width at stated intervals, so that their combined discharge capacity at their outlets is much greater than at the lake end. In a plan of drainage prepared by the writer (see Senate Document No. 89, pages 168 to 171), eight canals, having a discharge capacity at their out ', ' lets two and one-third times their capacity near the lake, were recommended as main arteries. The arrangement shown on this plan is not being strictly carried out by the Trustees, but ' the exact location of these canals is not a mat's ter of vital importance so long as the requisite 'I discharge capacity is provided..
