On level lands needing arti-ficial drainage a uniform system (Figs. 1 and 2) must beplanned that will provide drains for the entire area. Themost economical arrangement of such a system is one whichpermits the use of long laterals and requires the shortesttotal length of main drains. The advantage of this ar-rangement is shown graphically by Figures 1 and 2, inwhich the systems drain equal areas. The cost of pur-chasing and putting in the tile is, however, considerablygreater for the system shown in Figure 2. Size of the Tiles.—No hard and fast rule can be givenfor determining the sizes of tile to be used. Drains shouldbe large enough to remove the surplus water before thecrops
