NEW METHOD OF RDARING OAK. 241

 planted ones, in the bed which had received no lime. 

 The summer of 1825 was the last in which I had 

 an opportunity of attending to the growth of these 

 plants. They were then live years old, and the 

 difference of progress which had been made each 

 year, by the plants in the respective beds, rendered 

 the diversity of their size palpable and striking. 

 The oaks raised from acorns in the limed bed ex- 

 ceeded the height of those which had been raised in 

 the same manner, but without lime, a full foot, and 

 were as tall as ever I remember to have seen Scots 

 firs of the same age. The plants in the unlimed 

 acorn-bed were on an average eighteen inches taller 

 than the most forward transplanted ones, namely 

 those to which lime had been applied ; and these last 

 were from six to eight inches further forward than 

 the transplanted ones which had not had the ad- 

 vantage of manure. I observed, however, with re- 

 gard to those which had made the least progress^ 

 that they were farther advanced than any I had 

 ever seen treated in a similar manner in other re- 

 spects, but without the benefit of shelter. 



This experiment was, as I have already said, be- 

 gun in the year 1821. In order to avoid interrup- 

 tion, I have, as yet, taken no notice of three subse-
