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,
