OF DRAINING. 5"> 



at Tillylumb near Perth, who has invented a plan which 

 seemed to him a new one, though it will appear, that it 

 afterwards has been tried in foreign countries with success j 

 but that does not lessen the merit of the ingenious cultiva- 

 tor who first attempted it in Scotland. 



Mr Andrew states, that the ridges on his farm had for- 

 merly been broad, and much raised. His predecessor had 

 levelled them by the plough, and when he entered into the 

 farm, almost all the good earth had been thrown into the 

 old furrows, and completely buried ; the crowns of the old 

 ridges were at the same time so much stript of soil, that 

 they were scarcely fit to carry any thing. It was absolutely 

 necessary, however, to do something to bring the ground 

 into a better state. As it lay on a gentle slope, cross drain- 

 ing was attempted, but ineffectually. He had then resolved 

 to gather up the ground to the old ridges, by as many 

 ploughings as might be necessary to raise them nearly to 

 their former height, and to throw a drain into every furrow, 

 thus designing, by one operation, to dry the ground, to 

 equalize the soil, and to give it a fallow. When these ope- 

 rations were completed, he gathered up a small ridge into 

 the furrows above the drains, to protect them from the sur- 

 face water. The following sketch will give some idea of the 

 nature of the operation :

The breadth of the large ridges depends entirely upon 

 the size of the original ridges, which varies considerably. 

 As to the small ridges above the drains, they are about two
