Instances corroborative of this fact are too constantly seen on the roadsides 

 in summer, where places which have had water lying until late in the spring 

 are the first to dry up and crack when the heat of summer conies on. 



Without doubt, tile draining is the best and most durable, whilst other 

 methods may be cheaper in this country for instance, the use of split cedar 

 and, where they are available, filling the drains with stones. Cedar may be 

 used as follows, which is recommended by H. T. Thrift, of Hazelmere. He 

 says : 



" The cheapest plan I know of is to dig the drain 16 inches wide and 

 say 2 feet 6 inches deep; lay straight cedar rails, which are easily obtained 

 in the woods, along one side of the ditch, and lay boards 1 to 1% inches thick 

 and 16 inches long, one end resting on the rails and the other in the angle 

 of the ditch. If the boards are laid in carefully, this makes an excellent 

 drain and will last for many years, and costs complete, if the work is well 

 done, about 40 cents per rod. (See Fig. 1.)

Another plan which is frequently followed is to dig the drain to the 

 required depth, then take out from the centre of the bottom a channel about 

 6 inches wide and 6 inches deep. Over this lay split cedar crosswise or 

 lengthwise, and fill in with brush and then with earth, as shown in Fig. 2.

Underdrains should not be less than 2 feet 6 inches in the soils requiring 

 draining least and certainly deeper in stiff clay soils, say 3 feet 6 inches. 

 The deeper drains are more effective, and in the long run less expensive, as
