62 MR. W. J. TUTCHER ON NEW SPECIES 
nitida, first discovered in Hongkong, was found in Lantao a few 
years ago, but it is not known from elsewhere. Rhododendron 
Fordii and Rhododendron Westlandii have not been found out of 
Lantao. This gives some idea of what an interesting ground the 
New Territory is likely to prove. 
Economic Botany. 
Tree-planting has been carried out on a considerable scale in 
Hongkong, but owing to the poorness of the soil it has been 
confined principally to one species, Pinus Massoniana. Many 
other kinds of trees have been tried but without success, unless 
in particularly favoured situations. A beginning has also been 
made in the New Territory, and this will probably be considerably 
extended. 
There is very little land suitable for agriculture in Hong- 
kong, but in the New Territory there are some fine level tracts, 
and there sugar and rice are the principal crops. Within 
the last few years improved varieties of sugar-cane have 
been introduced by the Government and are proving a success. 
Since the British occupation pineapple cultivation has greatly 
extended on the southern slopes of Tai-mo-shan and on the 
island of Cheung I. Experimental cotton-growing has been takeu 
up within the last year, but I am not in a position to state with 
what result.
