XIX. Observations on, and Details of, some Experiments in 

 Ringing the Bark of Fruit and other Trees and Plants. Bi/ 

 Joseph Sabine, Esq. F.R.S. $c. Secretary. 



Read March 21, 1820. 



The publication of the Papers, on Ringing the branches of 

 Fruit trees, by Dr. Noehden, in the second volume of 

 the Transactions,* has directed the attention of several Fel- 

 lows of the Society, and other persons, to the subject. The 

 results of those experiments which have been communicated 

 to me, appear to be of sufficient importance to be collected 

 together ; as tliev will serve as guides to those who may wish 

 to make further trials, and will assist in ascertaining the causes 

 of the variety of effects which appear to attend the operation 

 on different plants. 



The practice of ringing or circumcising the branches of 

 fruit trees, in order to make them yield more produce, is not 

 novel ; it is not stated to be so in the Papers alluded to ; 

 but though occasionally used, it does not appear that much 

 enquiry has been made to discover the most advantageous 

 method, or the proper seasons, for performing the operation ; 

 nor have any reasons been distinctly assigned wtiy it should 

 be so particularly successful in some instances, and so en- 

 tirely devoid of benefit in others.
