 grow. 



Where large quantities of potatoes are grown, and 

 a large portion of the land is planted with potatoes, it 

 often happens that it is not convenient to plough the 

 whole of the land in autumn, but an endeavour should 

 be made to get it done as early as possible in winter. 

 The ploughing should be done, if possible, in dry 

 weather, and a deep furrow, rough or crested, should 

 be turned in preference to one which lies flat. No

implement has proved of greater gain to potato 

 growers than the modern chill-breast digging plough. 

 In the place of a solid core, compressed while being 

 turned by the ordinary plough, the furrow is lifted over 

 and falls lightly. The need of frost to make the land 

 friable after the chilled plough is not nearly so great 

 in the first ploughing, and the subsequent ploughings 

 are equally benefited. The draught is much lighter, 

 and the horse-labour throughout the whole of th 

 operations is greatly lightened.
