articles of our wants. Thus, notes for instance on 
camphor, vegetable tallow, real manna, maple-sugar, 
hickory-nuts, sandarac, turpentine, kauri, etc., must 
be sought among the timber-trees. Simultaneously, 
then, a geographic grouping of all these indicated 
plants will be effected, in order that at a glance may 
be indicated what from each particular country in 
various parts of the globe may be secured. The 
range of each recorded species is now already given 
with a view of affording a clearer insight into the 
adaptability of different climatic tracts and altitudes 
of this colony, or countries within the same isother- 
mal lines for special plants. Furthermore, to give to 
benefactors abroad, who may wish to let us partici- 
pate in their treasures of plants a more exact indica- 
tion of our varied climatic zones, it was found ex- 
pedient to append to this record a very succinet 
meteorologic schedule. Space did not admit of an 
enumeration of the many works of different nations, 
which may be consulted with advantage for follow- 
ing up the indications now given, but a list of the 
principal publications will be prepared for the supple- 
ment promised. It should, however, be stated, and 
this with regret, that the new work on vegetable in- 
dustrial productions, published very recently by Mr. 
J. Smith of Kew, and resting largely on the notes of 
the late Alexander Smith, derived from the collec- 
tions of Hooker’s Museum, did not yet reach this 
country. Notes may hereafter also be added, distin- 
guishing those plants which give an immediate re- 
~- turn in one season, and those which produce their 
yield only in variously-extended periods. Likewise 
‘might be discriminated between those plants from
