TILLAGE. 189 



They do not plough four inches deep at Scotto ; Mr. 

 Dyble remarked, that a piece was there ploughed five or 

 six inches deep, and damaged for seven years : three inches 

 enough : the soil much of it a fine sandy loam, manifest- 

 ing no want of depth. 



Mr. Palgrave, at Coltishal, applies deep ploughing 

 in one case with singular judgment: he brings by water 

 from Yarmouth, large quantities of sea ouze, or haven 

 mud, this, on dry scalding gravels and sands, he trencli- 

 ploughs in without fear of burying, and finds, on experi- 

 ence, the effect very great, forming thus a cool bottom, 

 so that the surface burns no more. 



Mr. Johnson, of Thurning, thinks that it Is common 

 to plough too shallow ; nor does he believe that any mis- 

 chief results from depth. He has made a ditch one year, 

 and thrown it ^lown again the next, and the benefit was 

 seen for seven years, without the soil being adted on by 

 draining, or wanting it : nor is he nice to have his muck 

 ploughed in shallow, having no fear of burying it. By 

 ploughing a good pitch for turnips, they come slow to the 

 hoe, but when they do get hold, thrive much faster than 

 others. 



Mr. Reeve, of Wighton, is an advocate for deep 

 ploughing ; he goes five inches deep ; if I did not I should 

 get no turnips. 



Mr. DuRSGATE approves of deep ploughing; remark- 

 ing, that he breaks up his ollonds deeper than most people. 



Mr. Willis observing the marie on his land was sunk 

 below the common path of the plough, turned it up again 

 by going a deeper pitch, and found it to answer nearly as 

 well as a new marling ; and he suffered no inconvenience* 



The two furrow work about Holt, &c. is to turn a 

 furrow on lay or ollond ; the plough then returns and 

 throws It back with the untouched land that is under it,
