82 Improvements carry I fig on at Ca'ithnefs in l8o2. Feb. 



lime, which, including the expence of carriage, cannot be 

 calculated at lefsthan from 5I. to lol. per acre. From fome 

 experiments tried in the central counties of England, there 

 was reafon to believe, that burning tlic whole furface of 

 fuch a foil, was a cheaper and better mode of improve- 

 nent. As this was a mofl material point to afcertain, rt 

 was intended to make a trial on a large fcale ; but, owing 

 to the uncommon wetnefs of the feafon, only five acres 

 could be completed. The expence was as follows : — 



6 tons of coal and culm, at i6s. per ton - L. 4 16 o 

 Carriage of ditto from the fliore to the field - 010 o 

 40 cart load of peats, at is. each - - 200 



Additional expence of carriage, 13 of thefe cart- 

 loads being brought from a confiderable dif- 

 tance ---__ - ii# 



126 labourers (including women and boys) for 

 gathering and burning the fods, at is. on an 

 average - - - - 660 



Spreading the allies, at 6s. per acre - 1100 



Total - L. 16 3 o 



— or about 3I. 4s. 6d. per Scotch acre. Every thing is 

 here ftated at the higheft; rate ; yet there is hardly any mode 

 (unlefs in the immediate vicinity of dung or lime) where 

 that kind of foil could be made equally produCl:ive, at 

 double, or even triple the expence. It is proper to remark, 

 that the beft mode of burning the clay, is in fod kilns, fi- 

 milar to thofe in which they burn limeftone in feveral dif- 

 triclis. 



12. A number of other Agricultural Experiments have been 

 tried, In the courfe of this year. They are too numerous 

 to be detailed in a paper of this defcription ; but, the re- 

 fult of fome of the moft important of them, it may be pro- 

 per briefly to mention. 1. It appears that Winter wheat 

 is a much hardier grain than Winter rye. 2. Winter tares 

 cannot be depended on in the northern part of the ifland 5 

 but they may be fown early in Spring with much advan- 

 tage, and anfwcr better than what are called Spring tares, 

 being much hardier. They fhould be fov/n, however, im^ 

 mediately after the land is ploughed. 3. There is reafon 

 tp believe that carrots will anfwer on fen or mofly land, if
