many of the ridges, particularly near Kil- 

 narnock, arc by far too high railed, which 

 makes the furrows very poor, and hurts the 

 field very much when in grafs. 



A field of ridges eighteen feet broad, with 

 a moderate rife, when the water furrows are 

 all kept clean, will anfwer better both for 

 corns and grafs, and produce greater crops 

 than by having the ridges fo very high : For 

 when high, they caji never reverfe the ridges, 

 by making the crowns the furrows, and the 

 furrows the crowns, unlefs they bury the 

 whole manure, and bring up a new foil en- 

 tirely ; fo that they may as well bring in a 

 field from muir or wafte ground, as to at- 

 tempt to alter the ridges fuddenly. Whereas, 

 when the ridges are of a moderate rife, they 

 can be altered without any damage to the 

 foil. The great matter is, to keep the water 

 furrows clear both in fuminer and winter ; 

 and then, although very great rains fall, the 

 damage will not be great. 



The fifth obfervation is, I obferved them 

 in the month of January laying on lime up- 

 on thefe high ridges, when in grafs, all wet, 

 and in clods. 



By this method they lofe a great part of
