 the lines of section, the sod must be removed, 

 skinning it off as thinly as practicable and 

 stacking in a heap in some spot convenient, but 

 w^ell out of the way. The next operation is 

 to begin to dig out the valley. But should the 

 work be done after the method practised in 

 railway and other similar cuttings, the top, 

 and most valuable, soil would become buried

beneath the almost useless subsoil. Therefore 

 some other method must be adopted. A 

 practical way of doing this is to divide the 

 ground between the lines of section into plots 

 about 10 yards long ; each of these will then 

 measure about 30 feet long by 40 feet wide. 

 From the first plot remove the top spit to 

 say a depth of 6 inches, putting it in heaps 

 (Bi Bi, fig. i) on either side, and about 10 

 yards away. Next, dig out the soil down to 

 the subsoil, also putting it in heaps (B2 Bg) on 

 either side, and about 5 yards from ground
