Sargent makes statement OF the CONSIDERATIONS
which guided him IN Its preparation.
Evon in the inhospltable climate of Eastern
Massachusetts, a complete collection of all the
luovn natural and artificial varieties that could
be induced to live would occupy a
thousand acres of land and the number
of arborescent forms will no doubt considerably
increase. selection must therefore be made ana
the pIan ia TO establish two distinct collections
The first or exhibition collection VIII comprise lh-
diyiduas of selected species. and space Will be

he an experimenta or working collection, in which
snecies of doubtful hardness forms OF h0rtlcult-
ural rather than industrial or botanical value
new mtroductions and tho like can be crowded INTO
more narrow limits. The selection OF IN
diyiduals for tho permanent or repre-
sentative collection has proved the most DIM
cult task While containing types OF all
genera hardy in that region, no variety which Is
not fixed by time or long cultivation will be ad-
mtted American trees, and especially Now-Eng-
land trees, will be gwen the preference because
they can be trusted TO grow To maturity. Anu
whether the collection il considered from an Geo.
nomic scientific or decorative point of Wow, those
native trees that will grow under most favorable
conditions will be the most satisfactory III the END
Besides single trees for maximum development
group of each species will be added to show varia-
ton of individual character and to give their ex-
preston in mass and under something like natural
forest conditions. This group will not be added III
the case of the exotic species, except IN tew l-
stances where their peculiar value OF marked Mt
ness for our climate has been established.
Last year the provisional shrub plantation was
completed and 1 100 species and varieties are al
ready arranged in botanical sequence WIN room
