plantations, by breaking the force of cold winds, diminish 

 their chilling effect on the fields the plantations surround* 

 and render the climate on mountains much more mild and 

 genial. 



This last kind of improvement will generally be found 

 very greatly to exceed the expectation of the improver, 

 provided it be judicioufly planned and executed. 



C. WAISTELL, 



Additional Remarks*, 



Great loss is frequently sustained by omitting to thin Loss from not 

 plantations properly, and in due time, but I am not in pos- thinning plan- 

 gessioh of facts, to calculate with accuracy what this loss }„ 

 may be ; I will however venture to give a short statement of 

 some calculations I have made, as to the loss that would 

 now be sustained, by letting trees grow to a great age. 



In Miller's Gardener's Dictionary it is stated, that, in a and from let- 

 fall of oak timber in Lord Bagot's woods, Mr. Marshall ting trees stand 



. 1 • /- r 1 , . n too long 



Counted the rings of one tree, which was sound at the butt* 



and found the number to be about 200. Its bole was 22 

 feet long, and 108 inches in circumference in the middle. 

 Its contents 110 feet, which at 25. amount to 11/. T think 

 it was last year, that a fine sound oak tree was cut down, 

 between Shrewsbury and Oswestry in Shropshire, of 300 

 years of age, and sold by auction for 52/. 5s. — And under 

 my direction, many oak trees were cut down, some years 

 ago, that could not be less than 800, and some of them pro-* 

 bably 400 years of age, and even more. In Hunter's Eve- 

 lyn's Sylva is given the circumference of 10 trees, not one 

 of which was probably less than 500, and some of them pro* 

 bably 1000 years old. 



Lord Bagot's tree of 200 years old, above-mentioned, 

 would, at the present price of 3a. a foot, be worth l6/. lOi. 

 Supposing that 3s. a foot should continue to be the price 

 of oak timber, for the next 200 years, we will in(juire 

 what sum might be raised by growing four oak trees in 

 succession, upon the same spot of ground, each tree to 

 te cut down when 50 years of age, and that their boles
