Mr. French remarks, that the expenfe of 



improving bogs, equally fpoiigy and wet, with 

 this, is very considerable, for the drains will 

 for fome time fill up admoit as fad as made. 

 "When the draining is finifhed, the main drains 

 fhould be left five feet det- p, and the breadth 

 iuit. fufficient to keep the banks up: crofs drains, 

 of a fmalier dimeniion, muft be made, which, 

 when the bog is perfectly drained, may be filled 

 up again. As to the expenfe, he obferves, that 

 it muft neceffarily vary greatly : but the very 

 worft fort may be completely done for 61. an 

 acre. Manuring with gravel, lime, or clay, 

 may in general be eflimated at 61. Then Mr. 

 French would by all means plant potatoes, in 

 the trenching manner, for the fake of mixing 

 the manure, which is laid on with the furface 

 of the bog, and alfo for the ufe of the trenches, 

 as furface drains. The crop of potatoes, if a 

 moderate quantity of dung is fpread for them, 

 will be equal to any in the country, that is, 

 worth iol. an acre i but if no dung, they will 

 not more than pay the expenfe of iced, plant- 

 ing, and taking up. In the fpring after, dig it 

 flightly, levei the trenches, and fow oats ; the 

 digging will not colt more than io.s. an acre. 

 The crop of oats will be 1 2 barrels, or rye, will 

 be a great produce. With this corn, the grafs 

 feeds fhould be fown ; rye grafs (Ioliumperenne) 

 and white grafs (holcus lanatus) do well ; com- 

 mon hay feeds good. The firft year a car muft 

 not go on, but the hay brought off by men. 

 The fecond year it will bear cars, and would 

 then let for 10s. an acre, for three years only;
