28 AMERICAN FERN JOURNAL 
sensibilis, called the sensitive fern, is said to wither 
on being touched by the human hand, though the touch 
of other substances does not produce any similar ap- 
pearances.” 
American Fern Society 
Members of the Society will hardly need to be re 
minded that Carl Christensen’s Index Filicum is indis- 
pensable to students of fern classification and useful 
in any line of fern study. Having noted an inquiry 
for this work in the JouRNAL, Mr. Christensen now 
offers copies of it, including the Supplement, to mem- 
bers of the Fern Society only, for ten dollars each. 
This is the actual cost of the books to him. He makes 
only one condition—that the Society act as his agent 
in receiving orders and collecting payment—and asks 
that all orders, if possible, be sent to him at one time, 
in order to save trouble and expense in shipping. 
Members wishing to take advantage of this generous 
offer should send their orders, with remittance, to the 
Secretary, Mr. S. H. Burnham, R. D. 2, Hudson Falls, 
‘. Y. Deliveries will be made as soon as the books 
can be got from Denmark. Purchasers will be ex- 
pected to pay postal charges from Hudson Falls to their 
places of residence, 
ANNUAL REPORTS OF THE SOCIETY 
Reports of officers received up to the time of going 
to press are printed below. The President’s report 
is deferred until the nextsnumber in order to treat 
more fully the financial situation which the Society 
has to face owing to the greatly increased cost of pub- 
lishing the Journat. The Treasurer’s report is also, 
through no fault of his, delayed.
