Subscribers are requested to note that, with this 

 issue, the office of publication of the Forestry Quar- 

 terly is transferred from Cambridge, Mass., to Ithaca, 

 N. Y. where all business communications should be 

 addressed. This change of address does not apply 

 to the Editorial department, which remains in the 

 same hands and at the same address as before. 



Soon after the final issue of Volume X, a compre- 

 hensive index embracing the contents of the ten 

 volumes is to be issued, which will greatly enhance 

 the value of the set as a book of reference. It is ex- 

 pected that the index will contain about 100 pages 

 and that it will cost $1.00 per copy. 



As the edition will be limited, subscribers who de- 

 sire this index are requested to make early application 

 by postal card, addressing Business Manager Forestry 

 Quarterly, Ithaca, N. Y. Full sets of back volumes 

 can still be obtained. 



By a peculiar accident, the article on Rainfall, a 

 Factor of Tree Increment, printed on pages 222-228 

 of the present volume was credited to Francis Davis, 

 when it should have been credited to Chandler Davis. 

 Please correct.
