DRAINING THE LAND l6l 



roads or bridges, and to call tiles into use for every form 

 of drainage work. 



It may be said, in passing, that brush, poles, and box 

 drains, in fact, any form of wooden drains, are unsatis- 

 factory, for the reason that these materials, sooner or 

 later, rot and decay, thus requiring the entire operation to 

 be repeated again. 



Tiles: the perfect drain. Tile drains are the cheapest 

 that can be used. It would not be too much to say that 

 drainage by tiles is the perfection of drainage. Thou- 

 sands of practical tests in this country have demonstrated 

 the value of tile drainage, for these reasons: (i) when 

 once laid, a good tile drain will last for centuries ; (2) the 

 tile is out of reach of all cultivating tools ; (3) tiles fur- 

 nish the cheapest possible means of removing excess of 

 water from the soil. 



Tiles have become so common, there is no section in the 

 country, to-day, where drainage is practiced, that they 

 are not available and known. You will be making a mis- 

 take, most certainly, by employing any sort of drain other 

 than tile. 



We have many kinds of tiles. Many kinds, of many 

 makes, and of many shapes and styles, all of which have 

 been put upon the market. It is only necessary to say 

 that the round tile is most in favor, and most generally 

 accepted, wherever tile draining is performed. One of the 

 advantages of the round style is the ease of laying it, and 

 the ease of connecting it with the preceding tile. 



Distance between drains. The lay of the land, the fall, 

 the nature of the soil, all come into prominence, and must 

 be given due weight in laying out any system of land 

 drainage. 



Lands that are of heavy clay, for instance, necessarily 

 will call for more tile than other lands that are more open
