The iiicIIkkI (if |irc});iriii<4 land l)y iiicrely scarifyinff tlic surface of stul)l)lc 

 paddocks is stroiinly coiidemued, as it can (nily have a cliance of success in

Rolling and Harrowing. 



In soil wliicli is liable to ciust on the surface, i^ is desirable, wliere rolling 

 is necessary, to cany out tlic work before tlie seed is sown, anil not to roll 

 afterwards till the ci'op is faiily well i;i'own, anrl then to t'nilow with light 

 harrows drawn across the drill fui'rows. Soils vaiy so gri'atly that it is not 

 <lesirable to lay down any hard and fast rule on work of this kind, as much 

 can be learnt by obserNation on the part of cidtivators, nianv of wlium lia\f 

 a variety of soils under tlicir- vnw in which uniform treatment would be 

 undesirable. Under oui' conditions we liave usually found it best to leave 

 the land with the slight furrows foi'med by the di-ills, as an tncn suiface is 

 very liable to crust and cause the rainfall to run otl'.

The harrowing of growing ci-ops may be carried out until t he croi)s are 

 about 6 inches high, provided the soil is tirin cnouirh to keep the harrows from 

 penetrating deeply, l)ut it should not be done before the plants are well rooted. 



The best time foi- the operation is after the hind has been made fairly firm 

 i>y rain, as then there is less risk of damaging the crop by too deeply operating 

 with the tines of the harrow. r)amage to roots is thus decreased, and the 

 chance of injuring plants by means of the bars of the harrow is also lessened. 



Light harrows duly should be used, aiul tluy should be di'awn at riglit- 

 angles to the drill furrows. Care should also be taken to a\i)id harrowing 

 after anv of the straw joints have foi'med in the plants. 



Seed Selection. 



The importance of .seed selection is again impressed upon those wtio are 

 about to sow ; therefore, where individual farmers cannot afford a grader of
