they may be helped by cutting them down to a foot or 6 inches: for in 1750 I 

 planted some oaks from my grove of 1 7 1 9 into a poorer soil, and though they 

 lived, they were sickly ; so in 1761 I cut most of them down to 1 foot, and then 

 by cutting off the side shoots, in 3 or 4 years led them into a single stem, and 

 most of them are now thriving and handsome trees : it can hardly be seen where 

 they were cut off, and some are 4 feet round : I have used the same method with 

 unhealthy chesnuts, beech, hornbeam, and wych elm, with the same success. 



The aggregate Increase in Circumference of different Trees, divided into tenths of 



Inches of their annual Growth.
