454 On the Effects of anointing 



manner as it does when a tree is cut over. There are now nu- 

 merous fruit-buds on trees whicli had but few, and those few 

 were completely destroyed. 



I'ear-lrees. — These, tliough the more advanced fniit-buds 

 suffered, have been less injuriously affected than apple-trees. 

 Their fjrowth has been unusually via;oraus ; and great num!)ersof 

 new buds have been formed, covering branches which before were 

 naked. This I remarked particularly on a jargonelle. 



Plum-trees did not appear to suffer in any respect, but shot 

 out blossoms and wood vigorously. 



Peach-trees. — One tree, an old one, appeared to have been 

 totally destroyed. But on exaniining it carefully, I observed 

 some buds uhicli appeared alive. I cut all tlie branches down 

 to these buds, which have produced astonishingly fine shoots. 

 A young tree, which for a year or two had made so little pro- 

 gress, and api)oared so unhealthy, that it had been condemned, 

 has shot fortii in a surprising manner, and has become a very 

 handsome tree, I was not, at first, particular in my examination 

 of this tree, as, from its former appearance, 1 was not anxious 

 about it. It is probable, however, that the oil had not reached 

 the best buds. 



Apricot-trees were so much injured, that the shoots were 

 feeble, and the trees ultimately perished. I do not yet know 

 what the effect will be when the buds shall be carefully avoided 

 when the oil is applied. 



Cherry-trees were seriously injured. When I speak of injury^ 

 I mean, that in those cases where the buds were not spared, new 

 ones did not push forth, and the general health and vigour of the 

 tree seemed impaired. 



Vines, treated in this manner, without sparing the buds, die 

 down to the root, from which strong shoots are afterwards sent 

 up. When the buds are not touched, they grow vigorously. 

 But, on the whole, as the annual exfoliation of the bark admits 

 of its being easily removed, I am not inclined to advise the ap- 

 plication of oil to vines. 



Gooseberry and Currant-bushes did not appear to derive any 

 benefit, but seemed to me rather injured by the oil. 



Those peach-trees which were not oiled, were as usual infested 

 with aphides, wliile no insect of any kind was to be seen on those 

 which had been oiled. 



The apple aphis {A. lanigera) has been entirely extirpated 

 from one garden, by means of oil applied to every part where 

 it appeared ; and I doubt not of its being soon destroyed in 

 every district of the kingdom which it has reached, if the same 

 means be used. 



While the experiments leading to the results now detailed
