Tile drains or lined ditches may prove moreeconomical in some localities, though the first cost be frequently property owners will contribute to the workto the extent of buying the tile, in preference to having anopen ditch through their property.

Above, a Paradise for Mosquitoes: Below, Not a Menace or Mosquito Producer. In more outlying regions or where something less costly thanthe tile drain but better than the open ditch is desired, a linedditch may be used. These are especially desirable where, be-cause of washing, maintenance costs may be heavy. Tile of therequired size may be split lengthwise and laid in the bottom ofthe ditch, the ends being cemented together. Damaged or poorquality of tile may occasionally be used at a saving. A rein-forced concrete lining is also possible at a low cost. A strip ofchicken-wire netting furnishes the reinforcement and the con-crete lining is placed as desired in the bottom and as far upthe sides of the ditch as may be considered necessary. Cautionin the use of this type will be necessary where frosts are severeand heaving common. While it will not be possible in this article to enu
