1. Mr. E. Cheel exhibited three seedling plants of 

 Eucalyptus Smithii to show the rate of growth in certain 

 soil in its native district as against a check plant in richer 

 soil in the Sydney district. The seed from which the plants 

 were raised was collected from a very large tree near 

 Mount Jellore in October, 1915. Twenty-three seedlings 

 were raised altogether, all of which with the exception of 

 one, were planted in a shallow gully at Hill Top in Febru- 

 ary, 1916. A check plant was kept in a pot of rich black 

 soil at Ashfield near Sydney. The plants when planted out 

 at Hill Top were about 1 J inches high with three pairs of 

 opposite leaves. The smallest and the largest of the plants 

 at Hill Top were lifted and repotted again a fortnight ago 

 (November 18th) and are exhibited to show the comparative 

 growth with the check plant at Ashfield. The growths of 

 the plants are as follows: — Smallest plant from Hill Topi \ 

 inches high ; largest plant from Hill Top 4J inches high ; 

 check plant at Ashfield 1 ft. 9J inches high. It will be 

 seen from the above that the rate of growth in the ordinary
