downwards for a perch of 16^ feet in length ; but in the case of 

 mixed cutting, where rock intervenes, a small increase in price 

 is usual, making it, upon an average of drains and depths up to 

 4 feet, at the rate of 2hd- per perch for the cutting. 



The general cost for cutting, stoning, and fiUing-in runs thus : —

The cutting of all drains upon lands which have been formed

 be omitted), be always cut from 6 to 8 inches into the bed below, 

 .so that when filled in with stones these may be fairly placed 

 below the old current of the passing water. 



A 



SECTION OF BOG. 



Assuming that the head of the bog, as also all other upright or 

 side springs, are drained, and the land itself sufficiently settled 

 for improving operations (after lying some months), some consi- 

 deration is necessary as to the better plan of doing this, which 

 will be treated upon hereafter. 



Occasional Sprinr/s. — Should springs occur at particular levels 

 on tlie line of rock, and upon the moderately sloped lands, it may 

 be best to check their descent by making horizontal drains of 

 some length across the declivities of the hills, and tlius conduct 

 or empty them into the nearest brooks or open ditches. But 

 should these hoi'izontal drains run in line with the strata or strike
