Mr. E. N. Ward, Superintendent of the Sydney Botanic Gardens, has made some 
experiments in grafting Eremocitrus on the common Lemon, and his experiments are 
in progress. 
In pointing a moral as to the need for taxonomic study of the wild relatives of 
cultivated plants, Dr. Swingle admirably shows the way in regard to certain lines of 
investigation in the direction of plants belonging to the Orange and Lemon family. 
We in Australia, as compared with the United States, have little population and few 
botanists and horticulturalists at work on economic scientific investigations. But it 
would be an unworthy and an untenable position to take up to try and make ourselves 
and others believe that we are making the best of our opportunities. Let our fruit- 
growers get busy in improving their fruits and the hardiness of them, and Dr. Swingle's 
paper will give them many useful hints.
