DRAINING OF LAND. 219 



This mode of draining, the Major would recommend to be 

 always adopted, provided a sufficient quantity of stone can be 

 procured, even if the expense attending it should be somewhat 

 great, since it evidently must ensure its durability, almost for 

 ever, — when in the ordinary way of draining, without first 

 fl a gg' ,n o» or laying the bottom with stone, it will in no great 

 space of time give way by undermining the walling, or 

 soughing part, besides being more liable to fill or choke up 

 with earth or sediment. It would also be advisable to adopt 

 (as was done in this instance with good effect) the letting in 

 lots, of a given number of roods each, the cutting, stone- 

 digging, soughing, or walling, &"c. to different workmen } as 

 best calculated to ensure the well finishing and due performance 

 of each work. 



The draining being completed, covered, sodded, and levelled, Expenses, 

 and the same covered with about three thousand horse loads 

 of lime, and after adopting the greatest economy in the expen- 

 diture of this undertaking, the whole proved nearly as fol- 

 iows :

The value of the land in its improved state., in grass, was Value of the 

 calculated to be worth, for the first two or three' years, from „ iyes t § J/gQ* 

 two pounds ten, to five pounds fifteen shillings per acre ; but per cent. pro- 

 the proprietor has not the least doubt, from his experience in * 

 laying lime upon the surface of land of that description, and i 

 in the same neighbourhood, that from the end of the first 

 three years, it will be worth afterwards, and for some time, 

 (for grazing or fattening of cattle) from three pounds ten, 

 to three pounds fifteen shillings per acre, and, consequently, 

 will pay for the money so expended, at least eighteen or twenty 

 per cent,
