SIZE OF LATERAL DRAINS. 



149 



Tabulating Tile. 



After the engineer has determined the number and 

 size of the tile for each drain, he should note it upon 

 the field-book along with other particulars pertaining 

 to the drain. The tile of the whole field or system 

 should then be tabulated, an example of which is given 

 below, in order that a bill of tile according to size can 

 conveniently be made out, and also that they may be 

 distributed in the field without confusion . The follow- 

 ing plan may be followed in making this list. The 

 last column gives the total length of each separate 

 drain and should be used in checking the work.
