Depth, — Mr. Thurtell, at Gorlstonc, near Yar- 

 mouth, has a great opinion of deep ploughing; three or 

 four inches are a common depth about liim, but when 

 land is clean he always ploughs five, and sometimes six or 

 seven ; he is careful, however, not to do this on foul 

 land ; he has no apprehension ot breaking the pan, having 

 many times gone depth enough for that without any incon- 

 venience, and as to bringing up a dead soil, he has not 

 seen any ill efFedls from it : his land is a good sandy loam, 

 on a clay, marie or gravel. 



Mr. EvERiT, of Caistor, is of a different opinion ; he 

 is not fond of deep ploughing ; he thinks four inches deep 

 enough ; his ideas on this subje6l, however, seem to have 

 been chiefly the result of a trial made by his father, who 

 broke tha pan by trench- ploughing a piece of land, which 

 has ever since been full of charlock, &c. The dif- 

 ference of their soils will not account for tliis opposition 

 of sentiment : Gorlstone is a very good sandy loam at 20s. 

 or 25s. an acre, though certainly inferior in depth 'and 

 goodness to the land at Caistor. In discourse with these 

 two gentlemen on this subje6l, Mr. Everit remarked to 

 Mr. Thurtell, that if he ploughed deeper than com- 

 mon, he ought to add manure proportionably to the quan- 

 tity of soil stirred; an old idea of mine, and I remember 

 well, combated by my friend Arbuthnot. 



Mr. Francis, of Martham, ploughs four or five inches 

 deep. 



Mr. Cubit, of Honing, on a fine sandy loam, always 

 as shallow as possible ; and at East Ruston, where the soil 

 is exceedingly good, the same : he thinks the smaller quan- 

 tity of muck by this means answers.
