therein mentioned were being endangered by the publicity given to 
their haunts. We are glad to say, however, that the advertisement 
was cautiously drawn and, while giving an excellent idea of the rich- 
ness of the Aroostook flora, assigns stations to no plant which is not 
to be found in quantities to supply the herbaria of the world without 
the smallest danger of extermination. To illustrate it may be said 
that the elsewhere infrequent Aster Lznd/eyanus is the prevalent Aster 
in some parts of northern Maine where it is actually fought as a weed 
by farmers. Halenia deflexa, known from but one station in Vermont 
and not yet collected in New Hampshire, is common and abundant 
through much of Aroostook County. The interesting Oxytropis cam- 
pestris, var. johannensis covers the gravelly banks and shoals of the 
St. John river for many miles. "The dwarf mistletoe, one of very few 
plants to which the advertisement assigns a precise station, is, not- 
withstanding its botanical interest, a timber pest, present in all too 
great abundance. Drosera linearis, elsewhere unknown east of 
Lake Superior, is widely distributed on * Caribou Bog" which is 
thirty miles long and ten miles wide. Did space permit, the other 
species mentioned in the advertisement could likewise be shown, 
through their abundance or wide diffusion in northern Maine, to be 
in no danger whatever. From the examples already given it will be 
clear that any comparison between such lingering survivals as Camp- 
tosorus in densely settled regions or near popular resorts on the one 
hand, and these plants luxuriating in 10,000 square miles of fertile 
plains, wide-reaching bogs, and pathless forests of sparsely settled 
northern Maine on the other, is purely specious — a matter of words 
not facts. 
Considering the narrow limits within which the summer visitor now 
botanizes in certain classical collecting grounds on the White and 
Green Mountains, we can only express the hope that some part of 
the amateur collectors, who yearly visit these relatively restricted 
tracts of boreal and alpine flora, may through the influence of the 
advertisement be deflected to northern Maine, where, with a far 
greater opportunity to be of service to science, their collecting could 
have no serious influence upon the vegetation. Indeed, the flora of 
no other area east of the Rocky Mountains and south of British 
America seems to us less in need of concealment or special protection.
