18 ADDRESS BY THE PRESIDENT, NOVEMBER 3, 1875. 



Quick-lime, sulphur, turpentine, and tobacco, have all been recom- 

 mended. Carbolic acid has also been suggested as a remedy for 

 the attacks both of fungi and insects. 



The cause of disease in trees, and the mode of cure, should be 

 carefully studied by foresters. Much is still to be done in this 

 department; and the Members of our Society will do well to 

 direct attention to the subject, and to interchange any experience 

 they may gain. 



It will thus be seen that a forester requires to study various 

 departments of science, in order to be able to practise his profes- 

 sion in a satisfactory and intelligent manner. The information, 

 however, from books or lectures is not enough. The student of 

 forestry must enter practically into the subject. He must have 

 experience in planting, thinning, pruning, felling, and transplant- 

 ing of trees, as well as in draining. 



I believe that in the present day there is a great improvement 

 in the study of forestry, more especially in Scotland. We have a 

 great number of able and intelligent men in tins department, and 

 our Scottish Arboricultural Society is well calculated to encourage 

 forestry, and to train up men well qualified for undertaking the 

 duties connected with the growth of timber, both in this country 

 and abroad.
