266 TRANSACTIONS OF ROYAL SCOTTISH ARIJORICULTURAL SOCIETY. 



NOTES AND QUERIES. 



The Index. 



Owing to the initiative and generosity of the Earl of Crawford 

 we are able to publish in the present issue a detailed index of 

 the Transactions for the past sixty years. This will greatly 

 increase the value of the past issues by rendering their subject- 

 matter more readily available for reference. The index appears 

 at a very appropriate time in the history of the Society, as it 

 shows in a striking way the remarkable activity which has 

 prevailed in the Society concerning all phases of forestry for 

 the past sixty years. 



The Society is under a deep debt of gratitude to the Earl of 

 Crawford for this generous gift, which will be of great use and 

 practical value to the Society, and to all those interested in 

 forestry and forestry literature.

 were represented, and committees are now endeavouring to 

 simplify specifications and fix suitable prices, and to obtain 

 information regarding available supplies of material and labour 

 where the latter is scarce. The Board has also conferred with 

 the Railway Companies with the view of securing a reduction 

 in railway rates. Members who may have pitwood available 

 should send their names to the Secretary, who will gladly forward 

 further particulars when these are ready.
