this photographic survey. The photographs were taken by 

 Mr Walter Bell, and the subjects were selected by the Statistical 

 officers. 



The camera has an important and well-defined place in the 

 future development of forestry. Much experimental work will 

 have to be done in connection with the establishment and the 

 development of forestry in this country. This work, however, 

 will be in vain unless it is made available to, and utilised by, 

 those engaged in this industry. Photography will be of great 

 value as one of the means of incorporating the results of experi- 

 ments and research with existing practice. For instance, photo- 

 graphs can be used to illustrate improved methods in nursery 

 and saw-milling practice, to show the relative rates of growth of 

 different species under various conditions, to illustrate the various 

 methods of natural regeneration, and in many other ways. The 

 value of the systematic use of photography in forestry is being 

 recognised in other countries, e.g. America, where an intensive 

 use of the camera is to be made in connection with the Forest 

 Statistical Survey in that country. It is good to know that we 

 have not waited for other countries to show the way in this 

 matter, as the photographs exhibited and this brief description 

 show. 



The photographs were classified as follows : — 



i. Photographs illustrating stands of Mature Timber. 



As is well known a large proportion of the mature timber in 

 this country was cut for war purposes. Both on general and 

 technical grounds it would have been a misfortune if these 

 woods had disappeared without any records being left of them. 

 In many cases, however, complete technical statistics and photo- 

 graphs were obtained before their demolition. The photographs 

 exhibited in this group were intended to illustrate some of the 

 more notable of these woods. The Scots pine exhibits included 

 a photograph of a sample plot at Langlee, Jedburgh — elevation 

 above sea-level, 500 feet; age of wood, 124 years; mean height, 

 90 feet; volume, quarter girth, under bark, 8600 cub. feet. 

 Another photograph illustrated a portion of the Orton Wood, 

 Elginshire. This portion was a mixture of Scots pine and 

 larch — elevation, 300 feet; age, 125 years; mean height, 

 about 90 feet. A third photograph showed natural Scots 

 pine in Glen More Forest, Inverness-shire, at an elevation of
