may be reliable as to what may and what may not be 
planted. 
We have individuals enough in this country who are 
willing to spend money liberally for trees if they could 
find out what to buy, and how and where to plant. 
The early edition of this work, though quite up to the 
time when it was published, is now singularly meagre 
in its chapters on Evergreens, and there are probably at 
this moment in this country, collections, in extent and 
variety (though not in size of trees), greater than was 
the Pinetum at Dropmore, in England, which Mr. 
Downing refers to, in 1841. We are quite sure there 
are over ninety varieties of evergreens, nearly all quite 
hardy in this middle portion of the Hudson, which are 
not mentioned in the first edition, and there are several 
distinct, beautiful, and hardy genera not even alluded 
to, such as the piceas , of which there are at present 
known twelve distinct species, all, we believe, hardy 
here. Mr. Downing mentions seven abies, and we now 
have in cultivation, more or less general, twenty-three 
more. We have growing in the different collections in 
this country, principally between Washington and 
Boston, twenty more pines, in addition to the fifteen 
he enumerates, twenty-five junipers, against one in the 
first edition ; ten new ( Thujce ) arbor vitae, and seven 
yews. 
It may be objected that these are not all hardy. 
They may not be in one particular locality, but throughout 
the length and breath of our land, we have a sufficient 
variety of climate for e\ ery thing, and if one cannot grow 
a tree on the shores of Lake Erie, one can, perhaps, in 
Pennsylvania or Virginia, or the Carolinas, or Florida. 
Besides, as we shall hope to show, a great deal more may 
be done in planting doubtful trees (than is done) by a ju- 
dicious selection of site and soil. We further hope to 
show that in our best places where there is the desire 
and means to make large collections, that one should
