PREFACE. 



is the first printed catalogue that has been prepared for the Photo 



graphic collection at the Forest Research Institute, which comprises 

 the old collection of the Imperial Forest School together with additions 

 since the constitution of the Research Institute in 1906. This collection, 

 which is under the charge of the Sylviculturist, consisted on the 1st Novem- 

 ber 1911 of 1,433 photographs and 795 negatives. 



The photographic prints are classified under two separate indiees, I. Gen- 

 eral, II. Geographical (India only), the main sub-heads under each being 

 shown in the Table of Contents below. 



Negatives are classified according to size, to facilitate storage, the different 

 sizes being denoted by letters as follows :

Negatives of dimensions other than the above are classified under the size 

 most convenient for storage purposes. 



Officers are invited to add to the collection photographs of trees or any 

 subjects of interest in Forestry : these may be sent in the form of good prints, 

 negatives, or undeveloped plates. Prints and negatives will be returned, if 

 desired, after copies have been taken. Plates will be developed at the Forest 

 Research Institute free of charge, the negatives being returned, if desired, 

 after copies have been taken ; if the negatives are accepted, the cost of the 

 plates will be defrayed, should the return of the negatives not be desired. 

 All prints, negatives, or plates should be accompanied by a brief note as to the 

 subject and the name of the officer taking the photograph, and undeveloped 

 plates should, if possible, be accompanied by a note as to exposure, light, stop, 

 and plate used. ,.
