The stdes of the ditch shall be 

 (rue and smooth and shall slope 

 back from the bottom of the dttch 

 at an at* die flat enoutfh to prevent 

 the earth from falling, cavlnj or 

 slipping. 



Except solid rock no material stands 

 upright when cut with vertical sides. 

 All other materials wash and slide until 

 they come to a Certain slope, when they 

 will remain stationary. This is called by 

 engineers the natural slope. Now, if in 

 the beginning a ditch is excavated with 

 its sides inclined to the natural slope of 

 the materials th-ough whi h the channel 

 runs, it is certain that the sides being in 

 equilibrium will not need to adjust them- 

 selves by cavlnu and sliding. This nat- 

 ural slope of sides must be obtained in 

 one way and no other by cutting down 

 the earth exactly to slope plane and not 

 an inch farther. If the sides arc gouged 

 out haphazard beyond the slope plane 

 the ditcn can be made true to slope only 

 by trimming and filling, and as this must 

 be done with loose earth it cannot by 

 any ordinary amount of labor be made 

 as firm and as solid as the original soil.
