234 
months were becoming fewer, and that a sustained residence 
was required to achieve valuable work. The more obvious 
problems have been worked out. What is wanted now is to 
have good men, capable of seeing the most promising lines 
for research, attached to the staff of a tropical botanic garden, 
and to give to such men every opportunity for pursuing re- 
search. The visits of foreign students must of course be encou- 
raged just as before, but their investigations will be on the 
whole of decreésing importance in the work turned out by 
such a modern botanic garden. 
In conclusion, a very important line of work in a botanic 
garden is horticulture, with the concomitant feature of lands- 
cape-gardening, and this has in recent years become a very 
important direction in which tropical gardens have worked. 
They have wonderfully improved as picturesque and beautiful 
places of resort within the last twenty years, and now afford 
good schools of horticulture and landscape-gardening, besides 
doing much to introduce new and valuable ornamental plants. 
This is a line of work in which finality is not likely to be so 
soon reached as in introducing useful plants for agriculture, 
since new horticultural varieties are almost daily being produced. 
It will thus be seen, from this very brief sketch, that a 
botanic garden upon modern lines has an almost unlimited 
field of usefulness open to it, and in opening this field to- 
labour, Dr. Trrvs and the famous gardens under his direction 
have led the way.
