At the above rates, tlie saving by draining a farm of 500 acres 

 on the Keythorpe system would be more than 1200/. 



In Leicestershire Lord Berners pays for 3^-feet drains, equal 

 to nearly 7d. the statute perch ; and for 6-feet drains, equal to 

 \s. ^^d. the statute perch. In Norfolk his Lordship pays about 

 one-fifth less for labour. On the other hand the tiles made on 

 the estate would not be valued at more than 16^. the thousand 

 for 1^-inch pipes without collars, and 355. for 3-inch pipes. 



Others again, in other localities, would estimate both labour 

 and materials lower, viz., for digging 4i-feet drains, ^Id. the 

 statute perch, and for inch pipes 135. the thousand. 



At this rate the saving by the Keythorpe system over that of 

 equidistant drains, half of them at 8 yards distance and half at 

 10 yards, would be as under: —

The saving, even at these low prices, of IZ. 11 5. Qd. the acre 

 is an important consideration. 



I should state, however, that Lord Berners has informed me, 

 since the preceding calculations were made, that there are a few, 

 and a very few fields on which the drains have been as frequent 

 as if laid on the equidistant principle at intervals of 8 yards. 

 The fairest mode of estimating the advantages of the Keythorpe 

 system would, therefore, be by comparing the total number of 

 perches of drain on 500 or 1000 acres, with the total number on 

 another tract of land of the same extent and of the same kind of 

 soil on which all the drains have been laid on the equidistant 

 system. Lord Berners possesses, as I have said, the amplest mate- 

 rials for such a comparison ; and his Lordship would confer a gi'eat 

 public benefit if he would incur the trouble of having it made. 



In conclusion I would remark, that as a preliminary to drain-
