456 FOREST CULTURE AND 
The first installment of these additions is now sub- 
mitted to the Society’s supporters, and further sup- 
plemental notes may find their way perhaps also to 
publicity through the volumes of the Acclimatization 
Society, so far as the scope of its publications affords 
space for such purposes. Some difficuity was again 
experienced on this occasion, not only in the selection 
of the plants to be recommended, but also in the limi- 
tation of the notes on any particular species. But not 
every plant placed here is actually to be regarded as 
of proved, extensive, industrial value ; or as of estab- 
lished remunerative cultural yield; on the contrary, 
in the majority of instances they are only brought for- 
ward as recommendable for unbiased, new, and local 
tests by enlightened culturists. In reference to the 
narrow boundaries within which this and the two 
former treatises have been held, it may be observed 
that, until more voluminous writings of these kinds 
can appear through special public provision, the very 
brief data now additionally brought together may 
helpingly tend to the extension of cultural experi- 
ments, to the augmentation of our foreign intercourse 
for scientific, industrial, and mercantile purposes, and 
to the increase of our rural wealth.
