When scrapes or similar implements are used, it is custom-ary for the first working to be made with scrapes of the smaller.

The tirst tilling of corn can be muchmore rapidly done if the cultivating implement is supplied withfenders (Fig. 87), which are usually strips of metal attached to theplow beam and trailing along the ground between the implement 174 SOUTHEBN FIELD CROPS and the young plant to protect the latter from being covered bythe upturned soil. It is usually cheaper to Idll young grass along the line of thedrill by smothering it with earth thrown on it than by the use ofthe hoe; yet this worldng of the soil towards the plants shouldnot be carried to such an extent as to form high ridges along theline of the row. As a general rule, tillage implements with small points answerwell for the destruction of very young grass and weeds and forforming a surface mulch. But, if crab grass or other toughvegetation attains considerable size, it is usua
