THE BOOK OF THE LANDED ESTATE. 



inches deep cost 4f d. per rod, cutting and filling, while drains made in a 

 loam soil three inches deeper will cost the same ; but, generally speak- 

 ing, the greater the depth of the drain, the more expensive it will be. 



TABLE showing the NUMBER of PIPES required to drain an ACRE, and the COST. 



I generally calculate the expense of draining land per acre by first 

 taking the cost of opening out and filling in the drains per rood of seven 

 yards, adding to that the cost of the pipes for the same length, and 

 then finding out the number of roods in an acre ; this, of course, varies 

 with the width of the drains. Thus we find that there are in an acre, 

 when the drains are cut 



4 yards apart, 1 70 roods, of 7 yards each.

The statements given of the drainage of land throughout the country 

 vary very much, and this must be expected when we consider the many 

 different qualities of soils, the distance apart and depth of the drains, 

 and the convenience for the purchase and cartage of the pipes, all of 

 which influence in a more or less degree the cost of the drainage, so that 

 no siim can be put down as being the definite cost of drainage.
