extensively accessible for original observations and 
careful records. By these means, not only the knowl- 
edge of plants in all its branches is to be advanced 
through local independent researches, conducted in a 
real spirit of science, but also phytologic instruction 
is to be diffused to the widest extent; while simul- 
taneously, by the introduction of novel utilitarian 
species, local industries are to be extended, or new 
resources to be originated ; and, further, it is an aim 
to excite thereby a due interest in the general study 
and ample utilization of any living forms of vegeta- 
tion, or of important substances derived therefrom. 
All other objects are secondary, or the institution 
ceases to be a real garden of science. But the detail 
interpretation of these fundamental rules may be 
more or less rigorous, as the extent of the operations 
thus designed must very largely depend on the natu- 
ral facilities and monetary means which are at com- 
mand for the purpose. Moreover, the early attain- 
ment of any of these varied objects must evidently be 
all the more difficult in a new country, where, in the 
first generation, we are passing yet through the labo- 
rious and expensive process of founding all those in- 
stitutions from which, in the natural course of events, 
a later time can only derive the fullest benefit. But 
in all these planting operations, indicated for scientific 
demonstration, we can still find full scope for the dis- 
play of tasteful ornamentation and picturesque grand- 
eur. 
A real botanie garden, then, ought to display the 
living vegetation in its multifarious forms, as far as 
ever local circumstances will permit. All the plants 
of the globe build up together a great harmonious sys-
