Museums.—The Staff has been actively engaged during the 
-past year in determining and reporting upon a large and extremely 
varied number of economic products received from correspondents 
and visitors to the Museums. Questions relating to the identi- 
fication, origin, and uses of timbers and oil seeds show a consider- 
able increase over former years which appears to indicate that 
commercial firms are becoming better acquainted with this phase 
of the activities of Kew 
_ The facilities offered. ini the Museums for educational purposes 
have been put to good use by the London County Council and 
other educational bodies, for large numbers of school children 
accompanied by their teachers spent a good deal of time 
examining the collections during the summer months. 
uring the year special educational exhibits were brought 
together on several occasions. These included :—The Effects 
of Fog and Smoke upon Vegetation; Diseases Injurious to 
Forest and Fruit Trees; Mud and Sand-binding Plants; and 
Kitchen and Dairy Utensils made of Home-Grown Woods. 
The first-named exhibit directed attention to the deposits of 
dirt left upon the leaves of plants in the neighbourhood of London 
and other large cities during winter and the consequent enervating 
effect upon plant life. This was effected by the aid of sponged 
leaves contrasted with leaves as collected. In the same exhibit 
the serious effects of sulphuric acid, from fogs, upon plant life 
were shown. The disease exhibit illustrated some of the principal 
insect and fungus diseases with which gardeners and foresters 
have to gope. Various questions upon coast erosion made — 
necessary the exhibit of sand and mud-binding plants, whilst the 
great unemployment question created a fitting opportunity for 
an exhibit of articles made from home-grown timber, thereby 
showing how woodlands and their exploitation may exert @ 
considerable influence upon rural employment. 
As has been the case for many years an exhibit of specimens 
illustrating British Forestry was made at the Annual Exhibition 
of the Bath and West and Southern Counties Agricultural —— 
at Plymouth. As the Forestry Commission now undertake
