 every year by the Northamptonshire P'armino^ and Grazing 

 Society for this kind of draining ; also for pipe tile-draining ; and 

 last year at Broughton, near Kettering, there Avcre some very 

 excellent specimens of draining work.

The red and sandy soils have a natural drainage by reason of 

 the porous nature of the subsoil ; yet there too draining is some- 

 times needed to cut off the spring-water, which is often found 

 running along a stratum from 6 to 12 feet below the surface, and, in 

 consequence of meeting with obstruction in its course from a bed 

 of clay — frequently on the side of a hill — rises near to or runs 

 over the surface, and, from its extreme coldness and continued 

 flow, becomes very injurious to vegetation. In order to cure the 

 evil, care is required that the drains should be of sufficient depth, 

 and in the proper position, for catching the supply of water. In 

 some localities there are small plots of boggy ground completely 

 saturated by the rising of the water to the surface ; from the loose 

 and soft nature of the subsoil it is often very difficult to drain, 

 and it can only be done successfully by the drain cutting off the 

 supply. J. Boughton Leigh, Esq., who has lately been farming 

 part of his estate at Guilsborough, last year drained a bog of this
