1 64 A TREATISE ON THE CONNECTION OF 



ages under cultivation. Ten times the quantity of peat 

 or vegetable matter recommended to be given at once, or 

 480 tons, would scarcely bring poor barren land to the 

 colour of rich black mould, known in Scotland by the 

 name of Infield land, and to which, for ages, the dung of 

 the farm has been exclusively applied., 



Experiments made with an intimate mixture of poor 

 lean clay and peat warrant this assertion ; here purposely 

 stated, that the over sanguine cultivator, or improver of 

 ground, may not imagine, that with a summer fallow, 

 and a dunging, or dressing or two, he may be enabled to 

 complete so arduous a task. Land is always requiring a 

 supply of manure^ and repays in general more abun- 

 dantly for the last expence, when brought to an advanced 

 state of cultivation, than- for that which at first is in- 

 curred. Both seed and labour are thereby saved, and 

 good crops, wkh much more certainty, are to be depended 



Paring and burning the sward of some clayey soils- 

 may be practised with advantage, as the burnt clay wilt 

 diminish the stiffness of the soil, and render it more 



pervious
