 the coherence and compadtnefs of of the parts, 

 retains fo much water as will prevent it for a 

 long time foaking into the under-drains. On 

 the other hand, unlefs properly broken, and 

 tempered by manure, it becomics in a dry fea- 

 fon too rigid, and chokes the plants. This 

 double draining makes it expenfive. 



Some praftife the method of draining land 

 by laying it very high on the ridges, and very 

 low and hollov/ in the furrows* I by no means 

 approve of this ; for, when the land is after* 

 wards laid down for grafs, it is attended with 

 much more difficulty completely to drain it, 

 than if it had been m.ade only a little round up- 

 on the ridges. The furrows will retain water 

 and continue fwampy a long time, and produce 

 rudies j and the high ridges mud be cut through 

 in many places j which creates expence, and 

 wades much herbage. It may nor be unnecef- 

 fary to obferve, that where the ridges have been 

 raifed too high, and you wifii to level the 

 ground, you mud begin to raife a fmall land 

 in the furrow, and gather it larger and larger 

 by degrees. By fo doing you will make all 



parts
