In the inftance which I mofl: particularly 

 attended to, thirty acres of cold unproduiflive 

 land, lying on the (kirt of one of thofe hil- 

 locks, was, by undcrdraining, improved to 

 more than twice its formtr value. From a 

 ftate of rulhy ill-graffed fward, it was raifed 

 lirft to a piece of productive corn land, and 

 is now a found well-herbaged grazing- 

 ground. 



The MATERIALS wood. No flones in that 

 neighbourhood. 



In the MORELAND DALES undcrdraining

The OFFAL FREESTONES which lie an in-

 would pay w^ell for carriage into the bottom 

 of the Vale.

 the clearing and breaking up fuch lands for 

 the purpofes of agriculture.
