TILE-DRAINING 485 



ance. Nature alone did not remove the stumps and stones from 

 the wooded, stony lands. Neither does she irrigate the arid lands 

 of the West without the aid of man. 



5. Don't let damaging water get on to land, if it can be pre- 

 vented. An ounce of prevention is worth a pound of cure in 

 drainage. 



6. Don't think it takes a wizard to lay tile properly. Have a 

 survey made sufficient in detail to show that there is sufficient fall. 

 An intelligent use of this fall will then insure success. 



7. Don't install a part of a drainage system to which the re- 

 mainder of the system cannot later be joined with advantage. 



8. Don't let the waste banks of ditches grow up to weeds. Get 

 them sodded, and make them both valuable and attractive. 



9. Don't let outlet ditches remain idle when they should be 

 working. Have surface ditches and tile to keep them busy. 



10. Don't spend a dollar for small ditches or tile on a marsh until 

 an outlet is assured. 



11. Don't fail to give land drainage the attention and thought it 



deserves. 



" Our marshes and pot-holes are evils that tell : 

 Where corn shocks are thickest the land is drained well, 

 But justice to drainage demands first of all, 

 That we should drain wisely, or not drain at all." 



Road-drags 



Use of the King road-drag (Chase). 



The use of the drag is more satisfactory if the road has first been 

 crowned with a blade grader, but whenever this is not convenient and 

 the traffic is not too heavy, the road maybe gradually brought to a crown 

 by means of the drag (Fig. 19). 



The surface of the average country road should be covered in one 

 round with the drag. One horse should be driven on the inside of the 

 wheel track and the other on the outside, the drag being set, by means 

 of the chain, so that it is running at an angle of about forty-five degrees 

 with the wheel track and working the earth toward the center of the 

 road. In the spring, when the roads are more likely to be rutty and 

 soft it is generally better to go over the road twice and in some places 

 more times.
