Intrenching with a view to mixture and pulverisation {fig. 512.), all that is necessary isto open, at one corner of the plot, a trench or excavation of the desired depth, three orfour feet broad, and six or eight feet long. Then proceed to fill this excavation fromone end by working out a similar one. In this way proceed across the piece to betrenched, and then return, and so on in parallel courses to the end of the plot, observingthat the face or position of the moved soil in the trench must always be that of a slope,in order that whatever is thrown there may be mixed, and not deposited in regular layersas in the other case. To effect this most completely, the operator should always standin the bottom of the trench, and first picking down and mixing the materials, from thesolid side (a), should next take them up with a shovel, or throw them on the slope orface of the moved soil v6), keeping a distinct space of two or three feet between the For want of attention to this, in trenching new soils for plantations, or other purposes,it may be truly said that half the benefit derivable from the operation is lost. In generalin trenching, those points which were mentioned under digging, such as turning, break-ing, dunging, &c. required to be attended to, and sometimes an additional object—that ofproducing a level from an irregular surface—is desired. In this case double care isrequisite, to avoid forming subterraneous basins or hollows, which might retain water inthe substratum, at the bottom of the moved soil, and also to mix inferior with better soil,&c. where it becomes requisite to penetrate into depositions of inferior earthy removal of large stones, rocks, or ro
