Here, then, is the most satisfactory cvidoncr, flodnccrl from facts, 

 and from the practice of a man of acknowletlped science and observa- 

 tion, that it is utterly injurious even to youn^ trees, to mutilate their 

 roots or tops, in the way commonly practised . hence we must a fortiori 

 admit, that it is far more injurious to those of old trees ; and that the 

 more sedulously both are -presei-ved entire, the more vigorous will be 

 their development. 



In Note II. of the present Section, page 04, &c.. Miller, as we have 

 seen, so strongly reprobates the " bad philosoi)hy" (as he terms it), or 

 want of science, displayed by transplanters of large trees in his own 

 time, in lopping and lightening their tops, that it would be superfluous 

 to repeat it here ; but it is particularly deserving of the attention of the 

 reader. I have myself made several experiments, in order to compare 

 the different progress of trees, both young and old, that had their tops 

 lightened, with that of others, in which the tops had been left untouched, 

 and the results have been similar to those experienced by Miller ; only 

 in the latter, the results were more striking, on account of the more 

 advanced age of the trees. But I feel peculiar satisfaction in being able 

 to strengthen my own opinion, by the authority of so eminent a phytolo^ 

 gist, whose great work cannot be too frequently recommended to the 

 young planter's notice. It is most particularly valuable, in the edition 

 of the late Professor Martyn of Cambridge : who, besides nearly doub- 

 ling the whole matter contained in the original work, has added some 

 new and valuable articles, and brought the history of the plants enu- 

 merated down to the present times. 



Note VIII. Page 106. 



If the reasonings in the foregoing part of this Section be well founded, 

 the proposition in question here must necessarily be true, in respect to 

 trees removed from exposed to sheltered situations, as well as its con- 

 verse ; but probably there is no one who has verified it by experiment. 



In 1818, I transferred some beeches, oaks, witch-elms, limes, and 

 sycamores, from an exposed situation, in order to form a close skreen 

 of some size, in conjunction with underwood, which skreen or plantation 

 was accordingly executed. These trees possessed, in a very considera- 

 ble degree, what has been called in the text the Protecting Properties, 

 so that they might with great advantage have been set out in the open 

 park. In 1826, at the distance of eight years, it was quite visible, thdt 

 these properties had greatly disappeared, and that the non-protecting 

 were about tn be superinduced in their stead. In the spring of ihe
